Abstract
Background Despite a proven role in the characterization of liver lesions, use of the gadolinium-based contrast agent (GBCA) gadoxetate disodium at MRI is limited in children due to a lack of comparative safety data. Purpose To evaluate the safety of the GBCA gadoxetate disodium (a linear ionic hepatobiliary contrast agent [HBA]) in children and adolescents, compared with extracellular contrast agents (ECA). Materials and Methods A retrospective analysis was conducted in children and adolescents aged 18 years or younger who underwent HBA-enhanced MRI at one of three tertiary hospitals from January 2010 to December 2022. The incidence of GBCA-associated acute adverse events was compared between MRI examinations with a HBA and those with ECA. Severity was categorized according to American College of Radiology guidelines (mild, moderate, or severe). (a) Propensity score matching using multivariable logistic regression models and (b) inverse probability of treatment weighting analysis based on nine covariates (age, sex, asthma, allergic rhinitis, chronic urticaria or atopy, food allergy, drug allergy, premedication, and history of GBCA-associated adverse events) were used for confounder adjustment. Results A total of 1629 MRI examinations (ECA, n = 1256; HBA, n = 373) in 1079 patients were included (mean age, 8.6 years ± 6.5; 566 girls). The per-examination incidence of GBCA-associated acute adverse events showed no evidence of a difference, with rates of 0.9% (11 of 1256 examinations) for ECA and 1.3% (five of 373 examinations) for HBA (odds ratio [OR], 1.55 [95% CI: 0.54, 4.46]; P = .42). Acute adverse events were all mild with ECA, whereas with HBA, they were mild for four patients and moderate for one patient. There was no evidence of a difference in the incidence of acute adverse events, even in propensity score matching (OR, 1.33 [95% CI: 0.30, 5.96]; P = .71) and inverse probability of treatment weighting analysis (OR, 0.84 [95% CI: 0.25, 2.86]; P = .78). Conclusion Gadoxetate disodium showed no difference in acute adverse events compared with ECA in children and adolescents, with further large-scale pediatric studies required to confirm its safety. © RSNA, 2024 Supplemental material is available for this article.

Abstract
INTRODUCTION In infants and young children, good image quality in MRI and CT requires sedation or general anesthesia to prevent motion artefacts. This study aims to determine the safety of ambulatory sedation for children with CHD in an outpatient setting as a feasible alternative to in-hospital management. METHODS We recorded 91 consecutive MRI and CT examinations of patients with CHD younger than 6 years with ambulatory sedation. CHD diagnoses, vital signs, applied sedatives, and adverse events during or after ambulatory sedation were investigated. RESULTS We analysed 91 patients under 72 months (6 years) of age (median 26.0, range 1-70 months; 36% female). Sixty-eight per cent were classified as ASA IV, 25% as ASA III, and 7% as ASA II (American Society of Anesthesiologists Physical Status Classification). Ambulatory sedation was performed by using midazolam, propofol, and/or S-ketamine. The median sedation time for MRI was 90 minutes (range 35-235 minutes) and 65 minutes for CT (range 40-280 minutes). Two male patients (age 1.5 months, ASA II, and age 17 months, ASA IV) were admitted for in-hospital observation due to unexpected severe airway obstruction. The patients were discharged without sequelae after 1 and 3 days, respectively. All other patients were sent home on the day of examination. CONCLUSION In infants and young children with CHD, MRI or CT imaging can be performed under sedation in an outpatient setting by a well-experienced team. In-hospital backup should be available for unexpected events.

Abstract
Magnetic resonance imaging (MRI) and CT perform an important role in the evaluation of neonates with congenital heart disease (CHD) when echocardiography is not sufficient for surgical planning or postoperative follow-up. Cardiac MRI and cardiac CT have complementary applications in the evaluation of cardiovascular disease in neonates. This review focuses on the indications and technical aspects of these modalities and special considerations for imaging neonates with CHD.

Abstract
Fundamento Dados sobre o uso de ressonância magnética cardíaca (RMC) em crianças no Brasil são escassos. Objetivos Buscamos oferecer informações sobre as práticas atuais de RMC pediátricas no Brasil. Métodos Um questionário foi enviado a médicos solicitantes de RMC de todo o país, cobrindo informações sobre si próprios, sobre seus serviços de RMC, contexto clínico dos pacientes e sobre os obstáculos para a realização de RMC em crianças. Para a análise estatística, um p < 0,05 bilateral foi considerado significativo. Resultados A pesquisa obteve 142 respostas. Foi relatado que a RMC está disponível para 79% dos respondentes, dos quais 52% raramente ou nunca a utilizam. As indicações mais comuns são cardiomiopatias (84%), pós-operatório de correção de tetralogia de Fallot (81%) e malformações do arco aórtico (53%). A complexidade do exame se correlacionou à relação RMC/cirurgia (Rho = 0,48, IC 95% = 0,32-0,62, p < 0,0001) e ao número de exames de RMC (Rho = 0,52, IC 95% = 0,38-0,64, p < 0,0001). A complexidade da RMC esteve associada à sua realização por cardiologistas pediátricos (RC 2,04, IC 95% 1,2-3,89, p < 0,01). Os principais obstáculos ao uso mais frequente de RMC foram o alto custo (65%), a necessidade de sedação (60%) e o número insuficiente de profissionais qualificados (55%). Conclusão A RMC pediátrica não é usada frequentemente no Brasil. A presença de um cardiologista pediátrico a frente dos exames esteve associado ao uso de RMC em pacientes mais complexos. O treinamento de especialistas em RMC pediátrica e a educação dos médicos solicitantes são passos importantes na direção de um uso mais abrangente de RMC no Brasil.

Abstract
BACKGROUND Cardiac computed tomography (CT) is increasingly used in pediatric patients with congenital heart disease (CHD). Variability of practice and of comprehensive diagnostic risk across institutions is not known. METHODS Four centers prospectively enrolled consecutive pediatric CHD patients <18 years of age undergoing cardiac CT from January 6, 2017 to 1/30/2020. Patient characteristics, cardiac CT data and comprehensive diagnostic risk were compared by age and institutions. Risk categories included sedation and anesthesia use, vascular access, contrast exposure, cardiovascular medication, adverse events (AEs), and estimated radiation dose. RESULTS Cardiac CT was performed in 1045 pediatric patients at a median (interquartile range, IQR) age of 1.7 years (0.3, 11.0). The most common indications were arterial abnormalities, suspected coronary artery anomalies, functionally single ventricle heart disease, and tetralogy of Fallot/pulmonary atresia. Sedation was used in 8% and anesthesia in 11% of patients. Peripheral vascular access was utilized for 93%. Median contrast volume was 2 ml/kg. Beta blockers were administered in 11% of cases and nitroglycerin in 2% of cases. The median (IQR) total procedural dose length product (DLP) was 20 mGy∗cm (10, 50). Sedation, vascular access, contrast exposure, use of cardiovascular medications and radiation dose estimates varied significantly by institution and age (p < 0.001). Seven minor adverse events (0.7%) and no major adverse events were reported. CONCLUSION Cardiac CT for CHD is safe in pediatric patients when appropriate CT technology and expertise are available. Scans can be acquired at relatively low radiation exposure with few minor adverse events.

Abstract
Gadolinium-based contrast agents (GBCA) used for MR imaging are a valuable imaging resource that has benefited patient management over last three decades and largely have a high safety profile. However, recently, adverse effects related to GBCA like nephrogenic systemic fibrosis (NSF) and asymptomatic gadolinium deposition in tissues including brain are concerning. While NSF has largely stopped occurring due to precautions and guidelines to not use GBCA in patients with poor renal function, the long term effects of gadolinium deposition, especially in brain, are not known at this stage. Cautious approach needs to be taken with risk-benefit analysis in each patient to avoid its administration when not necessary. In this review, authors discuss basics of gadolinium, mechanism of enhancement, agents in clinical use and safety issues, and in the end, offer some solutions for safety concerns.

Abstract
BACKGROUND Ferumoxytol, an "off-label" contrast agent, allows for better cardiac MRI quality as compared with gadolinium-based contrast agents. However, hypotension has been reported with the use of ferumoxytol for indications other than cardiac MRI. The purpose of our investigation was to evaluate the safety of ferumoxytol in children undergoing general anaesthesia for cardiac MRI. METHODS Medical records of children undergoing general anaesthesia for cardiac MRI were reviewed. Baseline demographic and medical characteristics, as well as imaging and anaesthetic duration and technique, were collected. The incidence of hypotension or other adverse events', need for vasoactive support, or airway intervention throughout the anaesthetic, was recorded. RESULTS A total of 95 patients were identified, 61 received ferumoxytol and 34 received gadolinium. There were no significant differences between groups with respect to age, weight, or baseline blood pressure. The incidence of low blood pressure - systolic or mean - after contrast administration did not differ between groups, and there was no difference in sustained hypotension or use of vasopressors between groups. One patient who received ferumoxytol had possible anaphylaxis. The image acquisition time (45 versus 68 min, p=0.002) and anaesthesia duration (100 versus 132 min, p=0.02) were shorter in the ferumoxytol group. CONCLUSION Transient low blood pressure was common in children undergoing cardiac MRI with anaesthesia, but the incidence of hypotension did not differ between ferumoxytol and gadolinium groups. The use of ferumoxytol was associated with significantly shorter scan time and anaesthesia duration, as well as a decreased need for airway intervention.

Abstract
UNLABELLED IntroductionThe right ventricular adaptations early after surgery in infants with tetralogy of Fallot are important to understand the changes that occur later on in life; this physiology has not been fully delineated. We sought to assess early postoperative right ventricular remodelling in patients with tetralogy of Fallot by cardiac MRI.Materials and methodSubjects with tetralogy of Fallot under 1 year of age were recruited following complete surgical repair for tetralogy of Fallot. Protocol-based cardiac MRI to assess anatomy, function, and flows was performed before hospital discharge using the feed and sleep technique, an unsedated imaging technique. RESULTS MRI was completed in 16 subjects at a median age of 77 days (interquartile range 114). There was normal ventricular ejection fraction and indexed right ventricular end-diastolic volume (48±13 cc/m2), but elevated right ventricular mass (z score 6.2±2.4). Subjects requiring a transannular patch or right ventricle to pulmonary artery conduit had moderate pulmonary insufficiency (regurgitant fraction 27±16%).DiscussionEarly right ventricular remodelling after surgical repair for tetralogy of Fallot is characterised by significant pulmonary regurgitation, right ventricular hypertrophy, and lack of dilation. Performing cardiac MRI using the feed and sleep technique is feasible in infants younger than 5 months. These results might open new avenues to study longitudinal right ventricular changes in tetralogy of Fallot and to further explore the utility of unsedated MRI in patients with other types of CHDs.

Abstract
Gadolinium is a toxic rare earth element that is used as a contrast enhancement agent for diagnostic medical imaging. However, because of safety concerns to the developing fetus derived from preclinical studies, gadolinium can only be used during pregnancy if the potential benefits justify the potential risks to a fetus. Because there are no previous well designed safety studies on the developing fetus, we aimed to evaluate the potential adverse effects of in utero gadolinium exposure in high-risk premature infants. We performed a prospective dose (cord blood gadolinium concentration) - response (outcomes) study involving 104, 24-33 weeks gestational age (GA) infants. The mean (range) cord blood gadolinium concentration of infants measured using Inductively Coupled Plasma Mass Spectrometry was 191 (3.4-3729.6) pg/ml. The association between cord blood gadolinium concentration and each neonatal outcome was evaluated using linear or logistic regression analysis. The GA, race, gender, and antenatal steroid exposure were considered priori confounders. Recent adult human studies have shown that gadolinium exposure may be associated with nephrotoxicity. However, we found no adverse effects on renal function or other common outcomes including degree of prematurity, small for GA, respiratory distress syndrome, hyperbilirubinemia, intraventricular hemorrhage, necrotizing enterocolitis, patent ductus arteriosus, chronic lung disease, retinopathy of prematurity, and osteopenia of prematurity during the neonatal period with an increase in cord blood gadolinium concentration. None of the infants had clinically evident congenital malformations. In conclusion, gadolinium use during pregnancy is unlikely to be associated with adverse effects in infants during the neonatal period.

Abstract
BACKGROUND Analysis of safety reports has been utilized to guide practice improvement efforts in adult magnetic resonance imaging (MRI). Data specific to pediatric MRI could help target areas of improvement in this population. OBJECTIVE To estimate the incidence of safety reports in pediatric MRI and to determine associated risk factors. MATERIALS AND METHODS In a retrospective HIPAA-compliant, institutional review board-approved study, a single-institution Radiology Information System was queried to identify MRI studies performed in pediatric patients (0-18 years old) from 1/1/2010 to 12/31/2015. The safety report database was queried for events matching the same demographic and dates. Data on patient age, gender, location (inpatient, outpatient, emergency room [ER]), and the use of sedation/general anesthesia were recorded. Safety reports were grouped into categories based on the cause and their severity. Descriptive statistics were used to summarize continuous variables. Chi-square analyses were performed for univariate determination of statistical significance of variables associated with safety report rates. A multivariate logistic regression was used to control for possible confounding effects. RESULTS A total of 16,749 pediatric MRI studies and 88 safety reports were analyzed, yielding a rate of 0.52%. There were significant differences in the rate of safety reports between patients younger than 6 years (0.89%) and those older (0.41%) (P<0.01), sedated (0.8%) and awake children (0.45%) (P<0.01), and inpatients (1.1%) and outpatients (0.4%) (P<0.01). The use of sedation/general anesthesia is an independent risk factor for a safety report (P=0.02). The most common causes for safety reports were service coordination (34%), drug reactions (19%), and diagnostic test and ordering errors (11%). CONCLUSION The overall rate of safety reports in pediatric MRI is 0.52%. Interventions should focus on vulnerable populations, such as younger patients, those requiring sedation, and those in need of acute medical attention.

Abstract
PURPOSE OF REVIEW Spurred by numerous recent technological advances, cardiac MRI (CMR) is now the gold standard for anatomic evaluation, quantitative assessment of chamber size and function, flow quantification, and tissue characterization. This review focuses on recent advances in pediatric and congenital CMR, highlighting recent safety data, and discussing future directions. RECENT FINDINGS CMR has become an important component of risk stratification and procedural planning in numerous congenital and pediatric heart diseases. Innovative approaches to image acquisition and reconstruction are leading the way toward fast, high-resolution, three- and four-dimensional datasets for delineation of cardiac anatomy, function, and flow. In addition, techniques for assessing the composition of the myocardium may help elucidate the pathophysiology of late complications, identify patients at risk for heart failure, and assist in the evaluation of therapeutic strategies. SUMMARY CMR provides invaluable morphologic, hemodynamic, and functional data that help guide diagnosis, assessment, and management of pediatric and adult congenital heart disease. As imaging techniques advance and data accumulate on the relative and additive value of CMR in patient care, its role in a multimodality approach to the care of this population of patients is becoming clear and is likely to continue to evolve.

Abstract
PURPOSE To assess the feasibility of ferumoxytol-enhanced anesthesia-free cardiac MRI in neonates and young infants for complex congenital heart disease (CHD). MATERIALS AND METHODS With Institutional Review Board approval, 21 consecutive neonates and young infants (1 day to 11 weeks old; median age of 3 days) who underwent a rapid two-sequence (MR angiography [MRA] and four-dimensional [4D] flow) MRI protocol with intravenous ferumoxytol without sedation (n = 17) or light sedation (n = 4) at 3 Tesla (T) (except one case at 1.5T) between June 2014 and February 2016 were retrospectively identified. Medical records were reviewed for indication, any complications, if further diagnostic imaging was performed after MRI, and surgical findings. Two radiologists scored the images in two sessions on a 5-point scale for overall image quality and delineation of various anatomical structures. Confidence interval of proportions for likelihood of requiring additional diagnostic imaging after MRI was determined. For the possibility of reducing the protocol to a single rapid sequence, Wilcoxon-rank sum test was used to assess whether 4D flow and MRA significantly differed in anatomical delineation. RESULTS One of 21 patients (4.8%, 80% confidence interval 0-11%) required additional imaging, a computed tomography angiography to assess lung parenchyma and peripheral pulmonary arteries. Only 1 of 13 patients (7.7%) with operative confirmation had a minor discrepancy between radiology and operative reports (80% confidence interval 0-17%). 4D flow was significantly superior to MRA (P < 0.05) for the evaluation of systemic arteries, valves, ventricular trabeculae, and overall quality. Using Cohen's kappa coefficient, there was good interobserver agreement for the evaluation of systemic arteries by 4D flow (κ = 0.782), and systemic veins and pulmonary arteries by MRA (κ > 0.6). Overall 4D flow measurements (mean κ = 0.64-0.74) had better internal agreement compared with MRA (mean κ = 0.30-0.64). CONCLUSION Ferumoxytol-enhanced cardiac MRI, without anesthesia, is feasible for the evaluation of complex CHD in neonates and young infants, with a low likelihood of need for additional diagnostic studies. The decreased risk by avoiding anesthesia must be balanced against the potential for adverse reactions with ferumoxytol. LEVEL OF EVIDENCE 2 J. MAGN. RESON. IMAGING 2017;45:1407-1418.

Free-breathing motion-corrected late-gadolinium-enhancement imaging improves image quality in children. Pediatr Radiol 2016; 46:983-90. [PMID: 26886912 DOI: 10.1007/s00247-016-3553-7] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/26/2015] [Revised: 12/16/2015] [Accepted: 01/21/2016] [Indexed: 10/22/2022]
Abstract
BACKGROUND The value of late-gadolinium-enhancement (LGE) imaging in the diagnosis and management of pediatric and congenital heart disease is clear; however current acquisition techniques are susceptible to error and artifacts when performed in children because of children's higher heart rates, higher prevalence of sinus arrhythmia, and inability to breath-hold. Commonly used techniques in pediatric LGE imaging include breath-held segmented FLASH (segFLASH) and steady-state free precession-based (segSSFP) imaging. More recently, single-shot SSFP techniques with respiratory motion-corrected averaging have emerged. OBJECTIVE This study tested and compared single-shot free-breathing LGE techniques with standard segmented breath-held techniques in children undergoing LGE imaging. MATERIALS AND METHODS Thirty-two consecutive children underwent clinically indicated late-enhancement imaging using intravenous gadobutrol 0.15 mmol/kg. Breath-held segSSFP, breath-held segFLASH, and free-breathing single-shot SSFP LGE sequences were performed in consecutive series in each child. Two blinded reviewers evaluated the quality of the images and rated them on a scale of 1-5 (1 = poor, 5 = superior) based on blood pool-myocardial definition, presence of cardiac motion, presence of respiratory motion artifacts, and image acquisition artifact. We used analysis of variance (ANOVA) to compare groups. RESULTS Patients ranged in age from 9 months to 18 years, with a mean +/- standard deviation (SD) of 13.3 +/- 4.8 years. R-R interval at the time of acquisition ranged 366-1,265 milliseconds (ms) (47-164 beats per minute [bpm]), mean +/- SD of 843+/-231 ms (72+/-21 bpm). Mean +/- SD quality ratings for long-axis imaging for segFLASH, segSSFP and single-shot SSFP were 3.1+/-0.9, 3.4+/-0.9 and 4.0+/-0.9, respectively (P < 0.01 by ANOVA). Mean +/- SD quality ratings for short-axis imaging for segFLASH, segSSFP and single-shot SSFP were 3.4+/-1, 3.8+/-0.9 and 4.3+/-0.7, respectively (P < 0.01 by ANOVA). CONCLUSION Single-shot late-enhancement imaging with motion-corrected averaging is feasible in children, robust at high heart rates and with variable R-R intervals, and can be performed without breath-holding with higher image quality ratings than standard breath-held techniques. Use of free-breathing single-shot motion-corrected technique does not compromise LGE image quality in children who can hold their breath, and it can significantly improve image quality in children who cannot hold their breath or who have significant arrhythmia.

Abstract
Pulmonary hypertension in the perinatal period can present acutely (persistent pulmonary hypertension of the newborn) or chronically. Clinical and echocardiographic diagnosis of acute pulmonary hypertension is well accepted but there are no broadly validated criteria for echocardiographic diagnosis of pulmonary hypertension later in the clinical course, although there are significant populations of infants with lung disease at risk for this diagnosis. Contributing cardiovascular comorbidities are common in infants with pulmonary hypertension and lung disease. It is not clear who should be treated without confirmation of pulmonary vascular disease by cardiac catheterization, with concurrent evaluation of any contributing cardiovascular comorbidities.

Abstract
PURPOSE OF REVIEW To summarize recent publications emphasizing the changes in the population of patients with congenital heart disease and trends in the anesthetic and perioperative care of these patients presenting for noncardiac procedures. RECENT FINDINGS It has been reported that children with congenital heart disease presenting for noncardiac surgery are at an increased anesthetic risk. This risk has become better defined. The patients at highest risk are infants with a functional single ventricle and patients with suprasystemic pulmonary hypertension, left ventricular outflow tract obstruction or dilated cardiomyopathy. Familiarity with the physiology and perioperative implications of the stages of single ventricle palliation is critical. The anesthetic approach, monitoring, conduct of surgery and postoperative care and outcomes are variable in this patient population. Recent literature reflects the growing number of children with ventricular assist devices and the management of these patients for noncardiac procedures. Cardiac imaging modalities provide diagnostic information, and strategies for reducing anesthetic risk for these procedures are of great interest. Pharmacologic trends and the application of technology are reviewed. SUMMARY The identification of high-risk patients, multidisciplinary decision-making and planning and careful anesthetic management and monitoring are critical for optimizing outcomes in children with congenital heart disease presenting for noncardiac procedures.

Abstract
Kawasaki disease (KD) is a vasculitis affecting the coronary and systemic arteries. Myocardial inflammation is also a common finding in KD post-mortem evaluation during the acute phase of the disease. Coronary artery aneurysms (CAAs) develop in 15-25% of untreated children. Although 50-70% of CAAs resolve spontaneously 1-2 years after the onset of KD, the remaining unresolved CAAs can develop stenotic lesions at either their proximal or distal end and can develop thrombus formation leading to ischemia and/or infarction. Cardiovascular magnetic resonance (CMR) has the ability to perform non-invasive and radiation-free evaluation of the coronary artery lumen. Recently tissue characterization of the coronary vessel wall was provided by CMR. It can also image myocardial inflammation, ischemia and fibrosis. Therefore CMR offers important clinical information during the acute and chronic phase of KD. In the acute phase, it can identify myocardial inflammation, microvascular disease, myocardial infarction, deterioration of left ventricular function, changes of the coronary artery lumen and changes of the coronary artery vessel wall. During the chronic phase, CMR imaging might be of value for risk stratification and to guide treatment.
