Abstract
OBJECTIVES Appendicitis poses diagnostic challenges. A correct diagnosis is important during pregnancy to avoid unnecessary surgery on the one hand and delayed surgery on the other hand, as both may negatively affect pregnancy outcomes. Clinical scores for risk-stratified management of suspected appendicitis are well established in adults but have not been validated during pregnancy. This nested case-control study evaluated the diagnostic accuracy of the Appendicitis Inflammatory Response (AIR) score and imaging during pregnancy. METHODS By cross-linking national Swedish health registries from a defined geographical area, we identified a cohort of 154 women who underwent appendectomy for suspected appendicitis during pregnancy and a matched cohort of 232 pregnant women admitted for acute abdominal pain and suspected appendicitis but with a discharge diagnosis of nonspecific abdominal pain (NSAP). All variables were extracted from medical records. The diagnostic value of AIR score and imaging was estimated for patients with a final diagnosis of appendicitis compared with patients with negative appendectomy and NSAP patients. RESULTS The final diagnoses for the operated patients were uncomplicated and complicated appendicitis in 49.4% and 26.6%, respectively, and negative appendectomy in 24.0%. Nearly half of all the patients underwent diagnostic imaging (41%), mainly by ultrasonography. The sensitivity and specificity of diagnostic imaging were 44.9% (95% CI 32.9%-57.4%) and 42.2% (95% CI 31.9%-53.1%), respectively. The area under the receiver operating characteristic curve of AIR score was 0.88 (95% CI 0.84-0.92) for all appendicitis and 0.90 (95% CI 0.84-0.95) for complicated appendicitis. The sensitivity for complicated appendicitis was 100% at a score of ≥4. The specificity for all appendicitis was 97% at a score of ≥9. CONCLUSIONS The results of this study suggest that the AIR score may be a suitable diagnostic tool for risk stratification of pregnant women with abdominal pain and suspected appendicitis but further validation among pregnant women is needed.

Abstract
OBJECTIVE Computed tomography pulmonary angiogram (CTPA) is important to evaluate suspected pulmonary embolism in pregnancy but has maternal/fetal radiation risks. The objective of this study was to estimate maternal and fetal radiation-induced cancer risk from CTPA during pregnancy. METHODS Simulation modeling via the National Cancer Institute's Radiation Risk Assessment Tool was used to estimate excess cancer risks from 17 organ doses from CTPA during pregnancy, with doses determined by a radiation dose indexing monitoring system. Organ doses were obtained from a radiation dose indexing monitoring system. Maternal and fetal cancer risks per 100,000 were calculated for male and female fetuses and several maternal ages. RESULTS The 534 CTPA examinations had top 3 maternal organ doses to the breast, lung, and stomach of 17.34, 15.53, and 9.43 mSv, respectively, with a mean uterine dose of 0.21 mSv. The total maternal excess risks of developing cancer per 100,000 were 181, 151, 121, 107, 94.5, 84, and 74.4, respectively, for a 20-, 25-, 30-, 35-, 40-, 45-, and 50-year-old woman undergoing CTPA, compared with baseline cancer risks of 41,408 for 20-year-old patients. The total fetal excess risks of developing cancer per 100,000 were 12.3 and 7.3 for female and male fetuses, respectively, when compared with baseline cancer risks of 41,227 and 48,291. DISCUSSION Excess risk of developing cancer from CTPA was small relative to baseline cancer risk for pregnant patients and fetuses, decreased for pregnant patients with increasing maternal age, and was greater for female fetuses than male fetuses.

Guidance for clinical practice using emergency and point-of-care ultrasonography. Acute Med Surg 2024; 11:e974.

Abstract
Owing to the miniaturization of diagnostic ultrasound scanners and their spread of their bedside use, ultrasonography has been actively utilized in emergency situations. Ultrasonography performed by medical personnel with focused approaches at the bedside for clinical decision-making and improving the quality of invasive procedures is now called point-of-care ultrasonography (POCUS). The concept of POCUS has spread worldwide; however, in Japan, formal clinical guidance concerning POCUS is lacking, except for the application of focused assessment with sonography for trauma (FAST) and ultrasound-guided central venous cannulation. The Committee for the Promotion of POCUS in the Japanese Association for Acute Medicine (JAAM) has often discussed improving the quality of acute care using POCUS, and the "Clinical Guidance for Emergency and Point-of-Care Ultrasonography" was finally established with the endorsement of JAAM. The background, targets for acute care physicians, rationale based on published articles, and integrated application were mentioned in this guidance. The core points include the fundamental principles of ultrasound, airway, chest, cardiac, abdominal, and deep venous ultrasound, ultrasound-guided procedures, and the usage of ultrasound based on symptoms. Additional points, which are currently being considered as potential core points in the future, have also been widely mentioned. This guidance describes the overview and future direction of ultrasonography for acute care physicians and can be utilized for emergency ultrasound education. We hope this guidance will contribute to the effective use of ultrasonography in acute care settings in Japan.

Abstract
OBJECTIVE To investigate the risk factors and the value of clinical prediction model for complicated appendicitis (CA) during pregnancy. METHODS Prospective analysis of pregnant patients who underwent appendectomy at a single tertiary care center between February 2020 and February 2023 and who ultimately had pathologically confirmed acute appendicitis (AA). According to intraoperative conditions and postoperative pathology, they were divided into the CA group and the uncomplicated appendicitis (UA) group. The two groups of patients were then compared in terms of demographic characteristics, disease features, ancillary tests and predictive models of acute appendicitis. RESULTS A total of 90 patients with AA in pregnancy were included, 21 of whom had CA in pregnancy and 69 had UA in pregnancy. Multivariate regression analysis showed that gestational week, neutrophil ratio and C-reactive protein (CRP) were independent risk factors for CA during pregnancy. Relative to the first trimester, the third trimesters had an increased risk of complicated appendicitis (OR = 12.48, 95% CI: 1.56-99.57, P = 0.017). Neutrophil ratio ≥85.30% (OR = 24.54, 95% CI: 2.59-232.72, P = 0.005) and CRP ≥34.26 mg/L (OR = 7.86, 95% CI: 2.18-28.38, P = 0.002) had a significantly increased risk of CA. The AIR and AAS score models were statistically different between the two groups, but with a lower sensitivity of 52.38% and 42.86%, respectively. CONCLUSION The third trimesters, neutrophil ratio ≥85.30% and CRP ≥34.26 mg/L may be key predictors of CA in pregnancy. The current scoring model is inadequate to identify complex appendicitis in pregnancy and further research is needed.

Abstract
BACKGROUND Complicated appendicitis during pregnancy directly affects the clinical prognosis of both mother and fetus. However, accurate identification of complicated appendicitis in pregnancy is fraught with various challenges. The purpose of this study was to identify the risk factors and to develop a useful nomogram to predict complicated appendicitis during pregnancy. METHODS This retrospective study involved pregnant women who underwent appendectomy at the Maternal and Child Health Hospital of Hubei Provincial from May 2016 to May 2022 and who ultimately had histopathological confirmed acute appendicitis. Univariate and multivariate logistic regression were applied to analyze clinical parameters and imaging features as a way to identify risk factors. Then, nomogram and scoring systems predicting complicated appendicitis in pregnancy were constructed and evaluated. Finally, the potential non-linear association between risk factors and complicated appendicitis was analyzed using restricted cubic splines. RESULTS Three indicators were finally identified for the construction of the nomogram: gestational weeks, C-reactive protein (CRP), and neutrophil percentage (NEUT%). To improve the clinical utility, the gestational weeks were divided into three periods (first trimesters, second trimesters, and third trimesters), while the optimal cut-offs for CRP level and NEUT% were found to be 34.82 mg/L and 85.35%, respectively. Multivariate regression analysis showed that third trimesters (P = 0.013, OR = 16.81), CRP level ≥ 34.82 mg/L (P = 0.007, OR = 6.24) and NEUT% ≥85.35% (P = 0.011, OR = 18.05) were independent risk factors for complicated appendicitis. The area under the ROC curve (AUC) of the nomogram predicting complicated appendicitis in pregnancy was 0.872 (95% CI: 0.803-0.942). In addition, the model was shown to have excellent predictive performance by plotting calibration plots, Decision Curve Analysis (DCA), and clinical impact curves. When the optimal cut-off point of the scoring system was set at 12, the corresponding AUC, sensitivity, specificity, Positive Likelihood Ratio (PLR), Negative Likelihood Ratio (NLR), Positive Predictive Value (PPV), and Negative Predictive Value (NPV) values were AUC: 0.869(95% CI: 0.799-0.939),100%, 58.60%, 2.41, 0, 42%, and 100%, respectively. The restricted cubic splines revealed a linear relationship between these predictors and complicated appendicitis during pregnancy. CONCLUSIONS The nomogram utilizes a minimum number of variables to develop an optimal predictive model. Using this model, the risk of developing complicated appendicitis in individual patients can be determined so that reasonable treatment choices can be made.

Abstract
The review is devoted to the role of laparoscopic appendectomy in surgical management of acute appendicitis in pregnancy. We analyzed reviews, prospective and retrospective studies in the PubMed, Google, the Springer Link online library, the Cochrane Systematic Review databases. The results of laparoscopic and traditional treatment of acute appendicitis in pregnant women were assessed. We analyzed clinical, epidemiological features in these patients, differential diagnosis of acute appendicitis in pregnant women, indications and contraindications for endoscopic treatment, features of laparoscopic procedures. Comparative assessment of laparoscopic and open surgeries for acute appendicitis in pregnant women was carried out. We also estimated the influence of surgical treatment of acute appendicitis on subsequent course of pregnancy.

Abstract
Many clinical conditions require radiological diagnostic exams based on the emission of different kinds of energy and the use of contrast agents, such as computerized tomography (CT), positron emission tomography (PET), magnetic resonance (MR), ultrasound (US), and X-ray imaging. Pregnant patients who should be submitted for diagnostic examinations with contrast agents represent a group of patients with whom it is necessary to consider both maternal and fetal effects. Radiological examinations use different types of contrast media, the most used and studied are represented by iodinate contrast agents, gadolinium, fluorodeoxyglucose, gastrographin, bariumsulfate, and nanobubbles used in contrast-enhanced ultrasound (CEUS). The present paper reports the available data about each contrast agent and its effect related to the mother and fetus. This review aims to clarify the clinical practices to follow in cases where a radiodiagnostic examination with a contrast medium is indicated to be performed on a pregnant patient.

Abstract
Although hormonal and anatomical changes that occur during pregnancy have been well documented, how these changes affect foot and ankle function are less understood. Changes during pregnancy in body mass, body-mass distribution, joint laxity, and muscle strength can all contribute to alterations in gait pattern that can lead to pain or injury to the foot and ankle. This review provides an overview of the various foot and ankle anatomic, biomechanic, and kinematic changes that occur during pregnancy. In addition, this article presents the most common causes of foot and ankle symptoms expressed by the pregnant patient population and discuss the management and treatment of each condition.

Abstract
Abdominal pain in pregnancy is a diagnostic challenge with many potential aetiologies. Diagnostic imaging is a valuable tool in the assessment of these patients, with ultrasound commonly employed first line. MRI is an excellent problem-solving adjunct to ultrasound and has many advantages in terms of improved spatial resolution and soft tissue characterisation. This pictorial review aims to outline the role of MRI in the work up of acute abdominal pain in pregnancy and provide imaging examples of pathologies which may be encountered.

International diagnostic guidelines vary significantly in their recommendations, making it difficult to determine an optimal policy for evaluation. RESEARCH QUESTION Which societal-level diagnostic guideline for evaluation of suspected PE in pregnancy is an optimal policy in terms of its cost-effectiveness? STUDY DESIGN AND METHODS We constructed a complex Markov decision model to evaluate the cost-effectiveness of each identified societal guideline for diagnosis of PE in pregnancy. Our model accounted for risk stratification, empiric treatment, diagnostic testing strategies, as well as short- and long-term effects from PE, treatment with low-molecular weight heparin, and radiation exposure from advanced imaging. We considered clinical and cost outcomes of each guideline from a U.S. health care system perspective with a lifetime horizon. Clinical effectiveness and costs were measured in time-discounted quality-adjusted life years (QALYs) and U.S. dollars respectively. Strategies were compared using the incremental cost-effectiveness ratio (ICER) with a willingness-to-pay threshold of $100,000 per QALY. One-way, multi-way, and probabilistic sensitivity analyses were performed. RESULTS We identified six international societal-level guidelines. Base-case analysis showed the guideline proposed by the American Thoracic Society-Society of Thoracic Radiology (ATS-STR) yielded the highest health benefits (22.90 QALYs) and was cost-effective, with an ICER of $7,808 over the guideline proposed by the Australian Society of Thrombosis and Haemostasis and the Society of Obstetric Medicine of Australia and New Zealand (ASTH-SOMANZ). All remaining guidelines were dominated. The ATS-STR guideline-recommended strategy yielded an expected additional 2.7 QALYs per 100 patients evaluated over the ASTH-SOMANZ. Conclusions were robust to sensitivity analyses, with the ATS-STR guideline optimal in 86% of probabilistic sensitivity analysis scenarios. INTERPRETATION The ATS-STR guideline for diagnosis of suspected PE in pregnancy is cost-effective and generates better expected health outcomes than guidelines proposed by other medical societies.

Predictive value of D-dimer and analysis of risk factors in pregnant women with suspected pulmonary embolism after cesarean section. BMC Pulm Med 2021; 21:391. [PMID: 34852800 PMCID: PMC8638256 DOI: 10.1186/s12890-021-01757-3] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2021] [Accepted: 11/17/2021] [Indexed: 12/11/2022] Open
Abstract
Background Acute pulmonary embolism (PE) is one of the leading causes of maternal mortality, and cesarean section is an established independent risk factor for PE. The diagnostic utility of D-dimer for PE in non-pregnant women has been well-established, but its role in women with suspected PE after cesarean section is unclear. Furthermore, the optimal threshold level in this patient population is unknown. Traditional D-dimer levels have low diagnostic specificity, resulting in many pregnant women being exposed to potentially harmful radiation despite negative diagnostic imaging results. This research aimed to optimize the clinical threshold for D-dimer to improve specificity while ensuring high sensitivity and to identify risk factors for PE after cesarean section. Methods This retrospective study of 289 women who underwent diagnostic imaging (ventilation/perfusion [V/Q] or computed tomographic pulmonary angiography [CTPA]) for suspected acute PE after cesarean delivery from 2010 to 2021 was conducted. Clinical data and laboratory indicators within 24 h postpartum including D-dimer levels were collected for analyses. Results The final analysis included 125 patients, among whom 33 were diagnosed with acute PE (incidence of 11.42%, 95% confidence interval 7.7–15.1). The receiver operating characteristic curve analysis suggested that a D-dimer cut-off value of 800 ng/mL had specificity of 25.26% and sensitivity of 100% for detecting PE. The cut-off value was adjusted to 1000 ng/mL with a specificity of 34.74% and a sensitivity of 96.67%. Using a D-dimer cut-off value of 800 ng/mL (instead of the conventional value of 500 ng/mL) increased the number of patients excluded from suspected PE from 9.6 to 18.4% without additional false-negative results. Of note, a history of known thrombophilia was significantly more common in patients with PE than in those without (P < 0.05). No other independent risk factors were noted in our study. Conclusions The D-dimer cut-off value of 800 ng/mL ensures high sensitivity and increases specificity compared to the conventional threshold of 500 ng/mL. Utilizing this higher threshold can reduce the number of unnecessary CT and subsequently unnecessary radiation exposure, in women after cesarean delivery. Prospective studies should also be conducted to verify these results. Supplementary Information The online version contains supplementary material available at 10.1186/s12890-021-01757-3.

Abstract
Some of the ethically most sensitive issues in radiation protection arise at imaging of pregnant-and potentially pregnant-patients and of newborn. This article reviews the current literature and recommendations on imaging during pregnancy and breastfeeding. Risks related to alternative non-ionizing radiation methods are also considered. With few exceptions, exposure of the fetus through radiography, computed tomography (CT) and nuclear medicine imaging can be limited to safe levels, although studies such as abdominal-pelvic CT cannot avoid significant exposure to fetuses. Eight to 10 weeks post-conception, the fetus has a thyroid which starts to concentrate iodide having crossed the placenta barrier resulting in unacceptably high doses to the fetal thyroid after administration of 131I- and even 123I-iodide and other radiopharmaceuticals with a high content of free radioiodine. Many radiopharmaceuticals are excreted through breast milk. Breastfeeding interruption recommendations should be followed to keep the effective dose to the infant below 1 mSv.

Abstract
During the last decades, there has been a growing demand for medical imaging in gravid women. Imaging of the pregnant woman is challenging as it involves both the mother and the fetus and, consequently, several medical, ethical, or legal considerations are likely to be raised. Theoretically, all currently available imaging modalities may be used for the evaluation of the pregnant woman; however, in practice, confusion regarding the safety of the fetus often results in unnecessary avoidance of useful diagnostic tests, especially those involving ionizing radiation. This review article is focused on the current safety guidelines and considerations regarding the use of different imaging modalities in the pregnant population; also presented is an imaging work-up for the most common medical conditions of pregnant women, with emphasis on fetal and maternal safety.

Abstract
Advanced imaging techniques are enhancing research capacity focussed on the developmental origins of adult health and disease (DOHaD) hypothesis, and consequently increasing awareness of future health risks across various subareas of DOHaD research themes. Understanding how these advanced imaging techniques in animal models and human population studies can be both additively and synergistically used alongside traditional techniques in DOHaD-focussed laboratories is therefore of great interest. Global experts in advanced imaging techniques congregated at the advanced imaging workshop at the 2019 DOHaD World Congress in Melbourne, Australia. This review summarizes the presentations of new imaging modalities and novel applications to DOHaD research and discussions had by DOHaD researchers that are currently utilizing advanced imaging techniques including MRI, hyperpolarized MRI, ultrasound, and synchrotron-based techniques to aid their DOHaD research focus.

Abstract
Trauma is one of the leading causes of mortality in pregnant women and significantly increases the likelihood of an unwanted termination of pregnancy. Particularly in severe trauma with an increased risk of significant maternal injuries, computed tomography (CT) remains the imaging modality of choice as it is comprehensively available, quick to carry out and has a high diagnostic accuracy in the detection and classification of life-threatening trauma-associated pathologies compared to other imaging techniques. Considering the radiation-associated risks, it is unlikely that a single, monophasic CT in the emergency trauma room will exceed the threshold of deterministic radiation damage; therefore, fetal malformations or fetal loss are not to be expected; however, there is a low stochastic risk for the delayed occurrence of radiation-induced cancer both for the child and the mother that can be considered small in comparison to missed or delayed diagnoses after severe trauma. Intravenous, nonionic iodinated contrast agents are not contraindicated during pregnancy and should be administered whenever their use would also be considered appropriate in a nonpregnant patient; however, unnecessary scans and, if possible, multiple contrast agent phases should be avoided in order to reduce radiation. Magnetic resonance imaging (MRI) has a major role in the subacute setting and constitutes an excellent problem solver for specific questions, such as the evaluation of discoligamentous injuries of the spine. Its use is deemed acceptable at any stage of pregnancy when the required information is considered important for the management of further treatment. Due to potential teratogenic effects of MRI contrast media containing gadolinium on the fetus, including an increased likelihood of fetal loss, they should only be administered with great caution and under strictly defined indications.

Abstract
PURPOSE OF REVIEW Pregnancy-associated lymphoma (PAL) is an uncommon entity that lacks detailed prospective data. It poses significant management challenges that incorporate maternal and fetal risks associated with treatment or delayed intervention. Herein, we review the current literature for the diagnosis, management, and supportive care strategies for PAL. RECENT FINDINGS Establishment of a multidisciplinary team, including hematology-oncology, maternal-fetal medicine, and neonatology, is critical in the management of PAL. For staging, ultrasound and MRI are preferred modalities with use of computerized tomography in select situations. Data for the safety and effectiveness of therapy for PAL is largely based on retrospective studies. The timing of lymphoma-directed antenatal systemic therapy depends on the trimester, gestational age, lymphoma subtype and aggressiveness, and patient wishes. Therapy in the first trimester is usually not advocated, while treatment in the second and third trimesters appears to result in similar outcomes for PAL compared with non-pregnant patients with lymphoma. An overarching goal in most PAL cases should be to plan for delivery at term (i.e., gestational age > 37 weeks). For supportive care, most antiemetics, including agents such as neurokinin-1 receptor antagonists, have been used safely during pregnancy. For prevention or treatment of infections, particular antibiotics (i.e., macrolides, cephalosporins, penicillins, metronidazole), antivirals (i.e., acyclovir, valacyclovir, famciclovir), and antifungals (amphotericin B) have demonstrated safety and with use of growth factors reserved for treatment of neutropenia (vs. primary prophylaxis). Therapy for PAL should be individualized with goals of care that balance maternal and fetal well-being, which should include a multidisciplinary care team and overall intent for term delivery in most cases.

Abstract
PURPOSE Pregnancy-associated breast cancer (PABC) is a rare disease. However, its expected incidence tends to be increased because of delayed maternal age. The purpose of this study was to describe the clinical, radiological, and histopathological characteristics of PABC cases diagnosed in our center. METHODS The clinical-radiological findings and histopathological characteristics of patients diagnosed and treated with PABC at our institution between January 2011 and January 2017 were retrospectively evaluated. RESULTS Mammography and ultrasonography were performed in all patients. MRI examination was performed in 18 patients. Nine (19.1%) out of 47 patients were diagnosed with breast cancer during pregnancy, and 38 (80.9%) were in their first year after delivery. The most frequent finding (95.7%) during imaging was one or more masses. Mammography-detected pure or accompanying microcalcifications were found in 12 (25.5%) patients. MRI detected additional multifocal and multicentric disease in 14 (29.8%) patients and contralateral cancer in one (2.1%) patient. CONCLUSIONS Pregnancy-related breast cancer tends to be diagnosed in an advanced stage with poor prognosis. Any breast abnormalities observed in this period should alert clinicians, and a meticulous radiological evaluation is mandatory. The early diagnosis of this disease would increase the chances of successful treatment.

Abstract
Abnormally invasive placenta (AIP) is used to describe a placenta that does not separate naturally after delivery and cannot be extirpated without causing abnormally high blood loss. Recently, the use of a standardized terminology for descriptors of AIP signs seen on ultrasound has been prosed but to date no such unified descriptors have been developed for magnetic resonance imaging (MRI). The purpose of this paper is to propose a unified terminology based on a consensus opinion from the members of the International Society for AIP (IS-AIP) that include obstetricians, gynecologists, radiologists, pathologists, anesthesiologists and basic science researchers. We assume that using these standardized MRI descriptors for AIP will be useful for clinical use, education, teaching and future research projects, thus assumably improving care of patients with this condition. In addition, using a uniform terminology for AIP should become the first step of a standardized MRI report.

Abstract
Fetal growth restriction (FGR) is often the result of placental insufficiency and is characterized by insufficient transplacental transport of nutrients and oxygen. The main underlying entities of placental insufficiency, the pathophysiologic mechanism, can broadly be divided into impairments in blood flow and exchange capacity over the syncytiovascular membranes of the fetal placenta villi. Fetal growth restriction is not synonymous with small for gestational age and techniques to distinguish between both are needed. Placental insufficiency has significant associations with adverse pregnancy outcomes (perinatal mortality and morbidity). Even in apparently healthy survivors, altered fetal programming may lead to long-term neurodevelopmental and metabolic effects. Although the concept of fetal growth restriction is well appreciated in contemporary obstetrics, the appropriate detection of FGR remains an issue in clinical practice. Several approaches have aimed to improve detection, e.g., uniform definition of FGR, use of Doppler ultrasound profiles and use of growth trajectories by ultrasound fetal biometry. However, the role of placental morphometry (placental dimensions/shape and weight) deserves further exploration. This review article covers the clinical relevance of placental morphometry during pregnancy and at birth to help recognize fetuses who are growth restricted. The assessment has wide intra- and interindividual variability with various consequences. Previous studies have shown that a small placental surface area and low placental weight are associated with a slower growth of the fetus. Parameters such as placental surface area, placental volume and placental weight in relation to birth weight can help to identify FGR. In the future, a model including sophisticated antenatal placental morphometry may prove to be a clinically useful method for screening or diagnosing growth restricted fetuses, in order to provide optimal monitoring.

Abstract
The incidence of cancer in pregnancy is increasing. The most frequent malignancies include breast and cervical cancers. Diagnosis may be complicated by late presentation. Imaging during pregnancy should consider risks to the fetus. Diagnostic work-up, including tumor markers, can be influenced by the physiology of pregnancy. Treatment of cancer can often be safely administered with good maternal and fetal outcomes. Chemotherapy, radiotherapy, and surgery must be adapted to the pregnancy state. Counselling and emotional support are an essential part of management.

Abstract
Health impacts of low-dose ionizing radiation are significant in important fields such as X-ray imaging, radiation therapy, nuclear power, and others. However, all existing and potential applications are currently challenged by public concerns and regulatory restrictions. We aimed to assess the validity of the linear no-threshold (LNT) model of radiation damage, which is the basis of current regulation, and to assess the justification for this regulation. We have conducted an extensive search in PubMed. Special attention has been given to papers cited in comprehensive reviews of the United States (2006) and French (2005) Academies of Sciences and in the United Nations Scientific Committee on Atomic Radiation 2016 report. Epidemiological data provide essentially no evidence for detrimental health effects below 100 mSv, and several studies suggest beneficial (hormetic) effects. Equally significant, many studies with in vitro and in animal models demonstrate that several mechanisms initiated by low-dose radiation have beneficial effects. Overall, although probably not yet proven to be untrue, LNT has certainly not been proven to be true. At this point, taking into account the high price tag (in both economic and human terms) borne by the LNT-inspired regulation, there is little doubt that the present regulatory burden should be reduced.

Abstract
OPINION STATEMENT Cardiovascular disease is an important cause of morbidity and mortality during pregnancy and the postpartum period. During pregnancy, the cardiovascular system undergoes extensive hemodynamic, hormonal, and microstructural changes which may exacerbate a preexisting underlying cardiovascular condition or predispose to cardiovascular complications not typically seen in young healthy women. Such conditions include spontaneous coronary artery dissection, atherosclerotic coronary artery disease, and peripartum cardiomyopathy. When evaluating this patient population, the diagnostic strategy should be tailored to specifically assess this distinct disease spectrum. The choice of imaging techniques must also consider potential risks to both the mother and child; a unique challenge of diagnostic imaging during pregnancy. The risk of radiation from radiography, computed tomography, and nuclear medicine imaging; iodinated and gadolinium-based contrast media for computed tomography and magnetic resonance imaging respectively; and heat deposition from sonography are of special importance during pregnancy. A thorough understanding of pregnancy-specific cardiovascular complications and the capabilities and risks of available diagnostic imaging modalities is crucial to appropriately manage the pregnant patient.

Abstract
BACKGROUND Acute appendicitis is the most common nonobstetric indication for surgical intervention during pregnancy. However, the current literature is scarce and composed of relatively small case series. We aimed to compare the presentation, management, and surgical outcomes of presumed acute appendicitis between a contemporary cohort of pregnant women and nonpregnant women of reproductive age. METHODS The study group included 92 pregnant patients who underwent appendectomy for presumed acute appendicitis at a single tertiary medical center in 2000-2014. Preoperative, operative, and postoperative clinical data were derived from medical records and compared to data for 494 nonpregnant patients of reproductive age who underwent appendectomy in 2004-2007 at the same institution. RESULTS Median age was 28 years (range 25-33) in the study group and 26 years (range 20-34) in the control group (P = 0.1). There were no between-group differences in mean white blood cell count, patient interval, hospital interval, or operative time. Preoperative abdominal ultrasound was used in a significantly higher proportion of patients in the pregnant group than in the nonpregnant group (73 and 27 %, respectively, P < 0.001) and computed tomography, in a significantly lower proportion of patients (1 vs. 16 %, respectively, P < 0.001) . The two groups had similar rates of negative appendectomy (23 and 22 %, P = 0.9), complicated appendicitis (12 and 11 %, P = 0.9), and overall postoperative complications (15 and 12 %, P = 0.3). CONCLUSIONS The clinical presentation and outcome of presumed acute appendicitis are similar in pregnant women and nonpregnant women of reproductive age. Therefore, similar perioperative management algorithms may be applied in both patient populations.

Abstract
PURPOSE The objective of the study was to evaluate the performance of magnetic resonance imaging (MRI) for the diagnosis of appendicitis during pregnancy. METHODS We conducted a retrospective review of all MRI scans performed at our institution, between 2006 and 2012, for the evaluation of suspected appendicitis in pregnant women. Details of the MRI scans performed were obtained from the radiology information system as well as details of any ultrasounds carried out for the same indication. Clinical and pathological data were obtained by retrospective chart review. RESULTS The study population comprised 63 patients, and 8 patients underwent a second MRI scan during the same pregnancy. A total of 71 MRI scans were reviewed. The appendix was identified on 40 scans (56.3%). Sensitivity of MRI was 75% and specificity was 100% for the diagnosis of appendicitis in pregnant women. When cases with right lower quadrant inflammatory fat stranding or focal fluid, without appendix visualization, were classified as positive for appendicitis, MRI sensitivity increased to 81.3% but specificity decreased to 96.4%. CONCLUSIONS MRI is sensitive and highly specific for the diagnosis of appendicitis during pregnancy and should be considered as a first line imaging study for this clinical presentation.

Abstract
Lymphoma is fourth most frequent malignancy diagnosed prenatally (~1:6000 cases), with Hodgkin's Lymphoma (HL) forming the major chunk. However, in recent times, there has been an increase in occurrence of Non-Hodgkin's Lymphoma (NHL) due to late child bearing age and high incidence of AIDS-related NHL in developing countries. Managing NHL in pregnancy involves intricate medical, ethical and psychological issues. Diagnostic and treatment delays may influence the prognosis for indolent cases. Seen the complexity of the management decisions associated with NHL, interdisciplinary and individualized approach becomes imperative for each woman. We present a case of 25-year-old G2P0010 at 32 weeks Period of Gestation (PoG) with right sided deep cervical lymphadenopathy, who was diagnosed as aggressive malignant NHL and was subsequently started on chemotherapy after confirmation of diagnosis and eventually had an optimal feto-maternal outcome. The critical appraisal of the accessible data, identification of controversies and unresolved issues and proposal of elucidations about varied facets of NHL in pregnancy are also provided.

Abstract
BACKGROUND Headache is one of the most common emergency department complaints with three million visits annually in the USA. This is further complicated with 30% of those emergency visits being for a hypertensive disorder of pregnancy. There is no currently well-established guideline for diagnostic imaging with a common concern being ionizing radiation exposure in pregnancy. The purpose of this study was to assess the difference in imaging studies ordered for pregnant and non-pregnant patients who reported to a tertiary care emergency department with headache. OBJECTIVE The purpose of this study was to assess the difference in imaging studies ordered for pregnant and non-pregnant patients who reported to a tertiary care emergency department with headache. STUDY DESIGN This retrospective cohort study identified all reproductive age female patients who presented to the emergency department with a chief complaint of "headache." They were then divided into cohorts based on pregnancy status. Rates and types of imaging studies utilized in patient evaluation were then compared. RESULTS Two thousand seven hundred ninety patients met our criteria for evaluation; 95 were found to be pregnant. Head CTs were ordered significantly less and MRIs were ordered significantly more in the pregnant cohort as compared to the non-pregnant cohort with a P value of <0.0001 and an odds ratio of 4.21 and a P value of 0.0127 and an odds ratio of 0.49, respectively. CONCLUSION Our data shows a difference in evaluation for pregnant patients as compared to their non-pregnant cohort. CT should not be considered contraindicated in the pregnant population and the amount of ionizing radiation to the fetus is well within the maximum safe dose, particularly with appropriate shielding. The time difference, cost, fetal exposure risk, and availability of CT compared to MRI should be taken into account when establishing a criterion for diagnostic evaluation. This difference validates the need for further research into a well-established guideline for the emergent evaluation of headache in the ED without special bias placed on pregnancy status.

Abstract
Pregnant women are most likely to have primary headaches, such as migraine and tension-type headaches, which can be diagnosed and treated without brain imaging. Primary headaches may even start de novo during pregnancy, especially in the first few months. However, when the headache occurs late in pregnancy or in the peripartum period, secondary causes of headaches need to be considered and evaluated by brain and/or vascular imaging, generally using magnetic resonance techniques. There is considerable overlap between the cerebrovascular complications of pregnancy, including preeclampsia/eclampsia, posterior reversible encephalopathy syndrome (PRES), reversible cerebral vasoconstriction syndrome (RCVS), and both hemorrhagic and ischemic strokes; although, their imaging may be distinctive. Imaging is necessary to distinguish between arterial and venous pathology causing headache in the peripartum patient, as there can be similar presenting symptoms. Mass lesions, both neoplastic and inflammatory, can enlarge and produce headaches and neurological symptoms late in pregnancy.

Abstract
OBJECTIVE The purpose of our study was to determine the current practice patterns of U.S. radiologists in imaging pregnant or potentially pregnant patients with acute abdominal and pelvic conditions. MATERIALS AND METHODS After obtaining an Institutional Review Board waiver, all members of the Association of University Radiologists, the Association of Program Directors in Radiology, and the Society of Radiologists in Ultrasound were invited via e-mail to take a 23-question online survey on radiology practices and clinical scenarios about acute abdominal and pelvic imaging of pregnant patients. RESULTS Comparisons were made with previously published surveys. A total of 225 responses were received. Areas of high consensus included pregnancy assessment (97%) and obtaining informed consent (87%) before imaging, having a written policy on imaging pregnant patients (79%), modification of computed tomography (CT) protocols (74%), avoiding gadolinium contrast in magnetic resonance imaging (MRI) (74%), using ultrasound for initial imaging in some scenarios, and using CT in trauma cases after inconclusive ultrasound. Areas of emerging consensus compared to 2007 included the use of serum or urine testing to confirm pregnancy status (59.4%; previously 14%) and the use of MRI in suspected appendicitis after an inconclusive ultrasound (73% in first trimester and 67% in third trimester; previously 46% and 29%, respectively). Areas without clear consensus included policy development, additional modifications to MRI protocols, choice of imaging modality, radiation dose, and the use of contrast agents in some scenarios. CONCLUSION In conclusion, high or increasing consensus exists in some areas of imaging pregnant patients with acute abdominal and pelvic conditions, but has yet to emerge in other areas.

Abstract
Pregnant patients can receive allergy premedication prior to a contrast-enhanced computed tomography exam if the exam is indicated. The risks and benefits of allergy premedication for pregnant patients will be discussed, as well as imaging strategies for the pregnant patient with a contrast allergy. Alternative imaging including ultrasound, noncontrast magnetic resonance imaging, or noncontrast computed tomography can be diagnostic depending on the clinical scenario and is usually preferred, allowing physicians to avoid giving allergy premedication in pregnancy, a 13 h delay, and risking a breakthrough reaction.

Abstract
BACKGROUND Ultrasonography is frequently used to diagnose acute appendicitis in women of reproductive age, but its diagnostic value in pregnant patients remains unclear. This study sought to compare the diagnostic performance of ultrasound in pregnant and young nonpregnant women with suspected acute appendicitis. METHODS The database of a single tertiary medical center was reviewed for all women of reproductive age who underwent appendectomy either during pregnancy (2000-2014) or in the nonpregnant state (2004-2007) following ultrasound evaluation. The performance of ultrasound in terms of predicting the final pathologic diagnosis was compared between the pregnant and non pregnant groups using receiver operating characteristic curve analysis. RESULTS Of 586 young women treated for appendicitis during the study periods (92 pregnant, 494 non-pregnant), 200 underwent preoperative ultrasound [67 pregnant, and 133 nonpregnant young women]. The pregnant and nonpregnant groups were comparable in age and presenting symptoms. There was no significant difference in the predictive performance of ultrasound between the two groups (AUC 0.76 and 0.73 respectively, p = 0.78) or within the pregnant group, by trimester [first (n = 23), AUC 0.73; second (n = 32), AUC 0.67; third (n = 12), AUC 0.86; p = 0.4]. Ultrasound had a positive predictive value of 0.94 in the pregnant group and 0.91 in the nonpregnant group; corresponding negative predictive values were 0.40 and 0.43. CONCLUSIONS There appears to be no difference in the ability of ultrasound to predict the diagnosis of acute appendicitis between pregnant women and nonpregnant women of reproductive age. Therefore, similar preoperative imaging algorithms may be used in both patient populations.

Abstract
As use of imaging in the evaluation of pregnant and lactating patients continues to increase, misperceptions of radiation and safety risks have proliferated, which has led to often unwarranted concerns among patients and clinicians. When radiologic examinations are appropriately used, the benefits derived from the information gained usually outweigh the risks. This review describes appropriateness and safety issues, estimated doses for imaging examinations that use iodizing radiation (ie, radiography, computed tomography, nuclear scintigraphy, and fluoroscopically guided interventional radiology), radiation risks to the mother and conceptus during various stages of pregnancy, and use of iodinated or gadolinium-based contrast agents and radiotracers in pregnant and lactating women. Maternal radiation risk must be weighed with the potential consequences of missing a life-threatening diagnosis such as pulmonary embolus. Fetal risks (ie, spontaneous abortion, teratogenesis, or carcinogenesis) vary with gestational age and imaging modality and should be considered in the context of the potential benefit of medically necessary diagnostic imaging. When feasible and medically indicated, modalities that do not use ionizing radiation (eg, magnetic resonance imaging) are preferred in pregnant and lactating patients. Radiologists should strive to minimize risks of radiation to the mother and fetus, counsel patients effectively, and promote a realistic understanding of risks related to imaging during pregnancy and lactation.

Abstract
Pregnant women with an acute abdomen present a critical issue due to the necessity for an immediate diagnosis and treatment; in fact, a diagnostic delay could worsen the outcome for both the mother and the fetus. There is evidence that emergencies during pregnancy are subject to mismanagement; however, the percentage of errors in the diagnosis of emergencies in pregnancy has not been studied in depth. The purpose of this article is to review the most common imaging error emergencies. The topics covered are divided into gynecological and non-gynecological entities and, for each pathology, possible errors have been dealt with in the diagnostic pathway, the possible technical errors in the exam execution, and finally the possible errors in the interpretation of the images. These last two entities are often connected owing to a substandard examination, which can cause errors in the interpretation. Consequently, the systemization of errors reduces the possibility of reoccurrences in the future by providing a valid approach in helping to learn from these errors.

Abstract
INTRODUCTION suspected appendicitis is the most common indication for surgery in non-obstetric conditions during pregnancy and occurs in about one in 500 to one in 635 pregnancies per year. This occurs more often in the second trimester of pregnancy. Acute appendicitis is the most common general surgical problem encountered during pregnancy. METHODS a literature review on research of scientific articles, under the terms "acute appendicitis" and "pregnancy", in PubMed, Lilacs/SciELO, Scopus, Cochrane Library and Uptodate databases. RESULTS the clinical manifestations of appendicitis are similar to non-pregnant women, however, without a classic presentation, which often occurs, diagnosis is difficult and must be supported by imaging. DISCUSSION clinical diagnosis should be strongly suspected in pregnant women with classic findings such as abdominal pain that migrates to the right lower quadrant. The main purpose of imaging is to reduce delays in surgical intervention due to diagnostic uncertainty. A secondary objective is to reduce, but not eliminate, the negative appendectomy rate. Differential diagnosis of suspected acute appendicitis usually includes pathologies considered in non-pregnant people. CONCLUSION the imaging study of choice is ultrasound, MRI may be used when the former is not conclusive and, as a last resort, a CT scan can be performed. The treatment remains appendectomy by laparotomy, since the feasibility of video- assisted surgery in these cases remains controversial.

Abstract
OBJECTIVE The purpose of this study was to determine the diagnostic performance of magnetic resonance imaging (MRI) in the diagnosis of acute appendicitis during pregnancy in a multiinstitutional study. STUDY DESIGN In this multicenter retrospective study, the cases of pregnant women who underwent MRI evaluation of abdominal or pelvic pain and who had clinical suspicion of acute appendicitis between June 1, 2009, and July 31, 2014, were reviewed. All MRI examinations with positive findings for acute appendicitis were confirmed with surgical pathologic information. Sensitivity, specificity, negative predictive values, and positive predictive values were calculated. Receiver operating characteristic curves were generated, and area under the curve analysis was performed for each participating institution. RESULTS Of the cases that were evaluated, 9.3% (66/709) had MRI findings of acute appendicitis. Sensitivity, specificity, accuracy, positive predictive value, and negative predictive values were 96.8%, 99.2%, 99.0%, 92.4%, and 99.7%, respectively. There was no statistically significant difference between centers that were included in the study (pair-wise probability values ranged from 0.12-0.99). CONCLUSION MRI is useful and reproducible in the diagnosis of suspected acute appendicitis during pregnancy.

Abstract
Abnormal placentation is responsible for most failures in pregnancy; however, an understanding of placental functions remains largely concealed from noninvasive, in vivo investigations. Magnetic resonance imaging (MRI) is safe in pregnancy for magnetic fields of up to 3 Tesla and is being used increasingly to improve the accuracy of prenatal imaging. Functional MRI (fMRI) of the placenta has not yet been validated in a clinical setting, and most data are derived from animal studies. FMRI could be used to further explore placental functions that are related to vascularization, oxygenation, and metabolism in human pregnancies by the use of various enhancement processes. Dynamic contrast-enhanced MRI is best able to quantify placental perfusion, permeability, and blood volume fractions. However, the transplacental passage of Gadolinium-based contrast agents represents a significant safety concern for this procedure in humans. There are alternative contrast agents that may be safer in pregnancy or that do not cross the placenta. Arterial spin labeling MRI relies on magnetically labeled water to quantify the blood flows within the placenta. A disadvantage of this technique is a poorer signal-to-noise ratio. Based on arterial spin labeling, placental perfusion in normal pregnancy is 176 ± 91 mL × min(-1) × 100 g(-1) and decreases in cases with intrauterine growth restriction. Blood oxygen level-dependent and oxygen-enhanced MRIs do not assess perfusion but measure the response of the placenta to changes in oxygen levels with the use of hemoglobin as an endogenous contrast agent. Diffusion-weighted imaging and intravoxel incoherent motion MRI do not require exogenous contrast agents, instead they use the movement of water molecules within tissues. The apparent diffusion coefficient and perfusion fraction are significantly lower in placentas of growth-restricted fetuses when compared with normal pregnancies. Magnetic resonance spectroscopy has the ability to extract information regarding metabolites from the placenta noninvasively and in vivo. There are marked differences in all 3 metabolites N-acetyl aspartate/choline levels, inositol/choline ratio between small, and adequately grown fetuses. Current research is focused on the ability of each fMRI technique to make a timely diagnosis of abnormal placentation that would allow for appropriate planning of follow-up examinations and optimal scheduling of delivery. These research programs will benefit from the use of well-defined sequences, standardized imaging protocols, and robust computational methods.

Abstract
Radiographic imaging of the pregnant patient represents a diagnostic and management dilemma for the orthopaedic surgeon. Imaging is often necessary in the setting of trauma; however, in utero radiation exposure can result in deleterious developmental effects in the embryo and fetus. The likelihood of a negative effect is proportional to the radiation dose and the gestational age of the embryo or fetus at the time of exposure. Ionizing radiation doses >100 mGy in the first trimester of pregnancy may lead to spontaneous abortion, malformation, and mental retardation. Whereas plain radiographs of the extremities and cervical spine expose the fetus to minimal doses of radiation of <10 mGy, other commonly performed orthopaedic diagnostic studies, such as CT of the pelvis, emit significantly higher exposure doses of approximately 35 mGy. Non-emitting modalities, such as ultrasonography and MRI, are alternatives for evaluation in the clinical setting.

Abstract
Evaluation of acute abdominal and pelvic pain in pregnancy presents a diagnostic challenge for clinicians and radiologists alike. The differential diagnosis includes obstetric and nonobstetric conditions unique to pregnancy, in addition to causes of acute abdominal and pelvic pain unrelated to the pregnancy. The clinical presentation and course of disease may be altered in pregnancy, and several pathologies are exacerbated by pregnancy. Discriminating clinical features in the diagnosis of abdominal and pelvic pain are often confounded by expected anatomic and physiologic changes in pregnancy. Moreover, while diagnostic pathways may be altered in pregnancy, the necessity for a timely and accurate diagnosis must be underscored, as delay in treatment may result in an undesirable increase in morbidity and/or mortality for both the patient and fetus. Advances in magnetic resonance imaging (MRI) through faster acquisition and motion-insensitive techniques, coupled with increased awareness and education regarding the value of MRI in diagnosing a wide range of pathology, have established MRI as a valuable strategy in the investigation of acute abdominal and pelvic pain in the pregnant patient. This review presents a practical approach to common obstetric and nonobstetric causes of acute abdominal and pelvic pain during pregnancy, as well as safety considerations for performing MRI in this patient population.

Abstract
Dynamic physiological and anatomical changes for delivery may adversely induce various specific non-obstetric complications during pregnancy and puerperal period. These complications can be fatal to both the mother and the fetus, thus a precise and early diagnosis ensued by an early treatment is essential. Along with ultrasonography, computed tomography (CT) and magnetic resonance imaging (MRI) have assumed an increasing role in the diagnosis. This article aims to discuss the pathophysiology of these complications, the indications for CT and MRI, and the imaging findings.

Abstract
There are multiple imaging modalities available for the assessment of pregnant women with known or suspected cardiac disease. Because of its safety and general availability, echocardiography is the preferred study of choice for the evaluation of ventricular function, valvular heart disease, congenital heart disease, evaluation of the aorta, and the estimation of cardiac hemodynamics in a pregnant patient. Cardiac MRI can be performed, especially for diseases of the aorta and complex congenital heart disease. Radiation exposure for the fetus and the mother will be discussed in the use of CT angiography, nuclear imaging, and left-heart catheterization including coronary angiography for specific indications in the pregnant woman. The use of exercise testing during pregnancy for functional assessment will be presented.

Abstract
Our attempts to systematically improve accuracy in the evaluation of patients with suspected appendicitis are, in some ways, hindered by the fact that the condition is so frequently straightforward to diagnose. Careful history-taking and physical examination are reliable in most patients. However, establishing the diagnosis with these skills alone remains vulnerable to conditions that masquerade as acute appendicitis. A substantial body of clinical research over the last quarter-century has shown that improved accuracy is possible. Strategies for improvement include the use of diagnostic scoring systems, laboratory makers such as CRP, diagnostic laparoscopy, and advanced imaging modalities such as CT, MRI, and US. How clinicians use these strategies depends on many factors related to practice setting, the population served, and clinical goals. In children, for instance, the desire to limit exposure to ionizing radiation competes with the greater anatomic detail that a CT scan can provide; at the same time, many hospitals that treat children do not have the resources to maintain the sort of full-time, highly sophisticated abdominal US programs that achieve the highest rates of diagnostic accuracy in clinical studies. Trade-offs have to be made, but improvement is possible in almost all groups of patients: the clinical community should no longer settle for a 15% NA rate when 5% is clearly possible without adverse consequences. Many clinicians will be faced with the task of evaluating patients suspected of having acute appendicitis. A deliberate, proactive, and, ideally, benchmarked strategy for improving diagnosis should be the standard to which we hold ourselves and the promise we deliver to our patients.

Abstract
Coronary artery disease complicates only 0.01% of all pregnancies. For this reason, more exhaustive data on the management of such cases is lacking. Even guidelines on management of cardiovascular disease in pregnant women are scarce focusing mainly on acute myocardial infarction. This is a complex issue involving thorough evaluation of cardiovascular status in each pregnant woman, assessment of risk for developing coronary complications, and close cooperation with obstetric teams. Safety data on typical cardiac drugs such as statins, angiotensin converting enzyme inhibitors, angiotensin receptor blockers, or novel antiplatelet drugs are also scarce and their effect on the developing human fetus is not well understood. We present a review on the management of such patients.
