Abstract
BACKGROUND Fasting before elective anesthesia care is a standardized practice worldwide. The aim is to decrease the risk of aspiration leading to pulmonary complications such as aspiration pneumonitis during anesthesia care. There are different guidelines for elective preoperative fasting in children. However, there is insufficient literature measuring gastric emptying time after breast milk or formula milk feeding in infants. OBJECTIVE This study used gastric ultrasound to determine the gastric emptying time for breast milk and formula milk in children below 6 months of age. We also compared the calculated gastric volumes among breast-fed and formula milk-fed based on Schmitz's and Spencer's formula. MATERIALS AND METHODS This prospective observational study was conducted at a tertiary care center in India between November (2017-2019). A total of 52 infants less than 6 months of age were recruited. The study population was divided into two groups (breast-fed and formula milk-fed) of 26 patients each. Ultrasound was used to measure the antral cross-sectional area of the stomach and to calculate the gastric volume using the two classical formulas (Schmitz and Spencer's). Gastric emptying was reported when the bull's eye appearance of the gastric antrum was seen or when the antral cross-sectional area was less than 3.07 cm2. RESULTS The number of breast-fed children whose antral cross-sectional was greater than 3.07 cm2 (cut-off value for aspiration risk) beyond 1 h was 14/26 (53.84%) while none (0) children went beyond 3 h. The number of formula-fed children whose antral cross-sectional was greater than 3.07 cm2 beyond 1 h was 17/26 (65.38%) while one child (3.84%) went beyond 3 h. Using Schmitz's formula, mean (SD) gastric emptying times were 0.35 ± 0.68 h (95% CI 0.35 ± 0.185, range 0.165-0.535) for breast-fed patients and 0.35 ± 0.69 h (95% CI 0.35 ± 0.188, range 0.162-0.538) for formula-fed patients, and were thus neither clinically nor statistically different (p = .73) Using Spencer's formula, the mean gastric emptying times were 0.12 ± 0.33 h (95% CI 0.12 ± 0.09, range 0.03-0.21) for breast-fed patients and 0.04 ± 0.20 h (95% CI 0.04 ± 0.05, range -0.01 to 0.09) for formula-fed patients, and were also neither clinically nor statistically different p = .13. CONCLUSION In our series, the gastric emptying times in breast-fed and formula-fed infants less than 6 months old were similar. Our results support the fasting guidelines of the European Society of Anaesthesiology and Intensive Care 2022, that is, 3 h for breastfeeding and 4 h for formula milk feeding. In addition, this shows that the Schmitz's and Spencer's formulae used to calculate the gastric volume based on ultrasound measurement of the antral cross-sectional area are not comparable in infants less than 6 months.

Abstract
BACKGROUND AND AIMS Lumbar vertebral bone attenuation, measured in Hounsfield units (HU) can indirectly indicate the bone mineral density (BMD). The aim of this study is to determine the optimal HU threshold on abdominal computed tomography (CT) scans to detect osteopathy in patients with chronic pancreatitis (CP). METHODS This cross-sectional study included patients with CP who underwent CT scans to measure HU at L1 to L4 vertebrae. The mean lumbar vertebral attenuation of female renal transplant donors, aged 20-30 years was utilized to calculate the T-scoreHU of all patients at each vertebral level. Receiver operator characteristic analysis was used to determine the HU and T-scoreHU for diagnosis of osteopathy in patients with CP. Dual-energy X-ray absorptiometry value was used to categorize osteopenia and osteoporosis. RESULTS A total of 175 patients (mean age, 34.5 ± 10.9 years; 72 % males) and 33 female renal transplant donors (mean age, 28 ± 2.4 years) were included. A threshold HU value 212 or T scoreHU of -1.80 at L1 vertebra was found to have a 78 % sensitivity and 70 % specificity for differentiating between osteoporosis and non-osteoporosis (osteopenia and normal BMD). Similarly, a threshold HU value of 254 or a T-scoreHU of -0.46 at L1 vertebra had 78 % sensitivity and 71 % specificity for distinguishing between normal and low BMD (osteoporosis and osteopenia). CONCLUSION Abdominal CT images, which are routinely performed in chronic pancreatitis, can be used for opportunistic screening of osteoporosis and osteopenia without additional cost or radiation exposure.

Abstract
BACKGROUND/PURPOSE Late hemorrhage following pancreatic surgery is associated with significant morbidity and mortality. Pseudoaneurysm (PSA) is an important source of late hemorrhage, which is effectively and safely managed by embolization. We aim to retrospectively review the outcomes of embolization for pseudoaneurysms causing late post-pancreatectomy hemorrhage over a period of six-years at our tertiary care center. METHODS Between 2014 and 2020, 616 pancreatic surgeries were performed and 25 patients had late hemorrhage (occurring > 24 hours post-operatively). The clinical parameters related to late hemorrhage, associated complications, embolization details, treatment success and their short-and long-term outcomes were analyzed. RESULTS Sixteen of 25 patients had PSA on digital subtraction angiography. Embolization was performed in these patients with technical and clinical success rates of 94.1% and 100%, respectively. Compared to patients without PSA, patients with PSA had significant hemoglobin drop (2.5 g/dL vs. 1.5 g/dL, p = 0.01), higher incidence of sentinel bleed (50% vs. 11.1%, p = 0.05) and lower requirement for surgery for bleeding (0% vs. 44.4%, p = 0.02). Clincally relevant postoperative pancreatic fistula and bile leak were seen in 72% and 52% of patients, respectively. Eight of these embolized patients died due to sepsis. The long-term outcome was good, once the patients were discharged. CONCLUSION Late hemorrhage after pancreatic surgery was associated with high mortality due to complications such as pancreatic fistula and bile leak. Sentinel bleeding was an important clinical indicator of PSA. Angiographic embolization is safe and effective without any adverse short or long-term outcomes.

Abstract
PURPOSE To evaluate the utility of dual energy CT angiography (DECTA) in acute non-variceal gastrointestinal hemorrhage (ANVGIH) compared to digital subtraction angiography (DSA) as gold standard. MATERIALS AND METHODS 111 Patients (mean age: 39.2 years; 94 males) of ANVGIH who underwent both DECTA and DSA between January 2016 and September 2021 were included. Virtual monochromatic (VM) images at 10 keV increments from 40 to 70 keV and blended (120kVp equivalent) images of arterial phase of DECTA were evaluated independently by two readers blinded to DSA information. Quantitative analysis included measurement of attenuation in the major arteries (abdominal aorta, celiac artery, superior mesenteric artery), suspected vascular lesion, and lesion feeding artery to calculate contrast-to-noise ratios (CNRs) and signal-to-noise ratios (SNRs). Qualitative analysis assessed the image quality of each data set using a 3-point Likert scale. Findings on DSA were evaluated by a third reader and both DECTA and DSA were compared. RESULTS On linear blended images, vascular lesion was identified by reader 1 in 88 (79.3%) and by reader 2 in 87 (78.4%) patients and DSA showed lesion in 92 (82.9%) patients. The sensitivity and specificity of blended images and VM images of DECTA for lesion detection were not significantly different from each other. The CNR and SNR of arteries, vascular lesion and feeding artery were significantly higher at 70 keV (p < 0.005) compared to blended and other VM images. Although subjective scores for image quality were higher for 60 keV images by both readers, the difference was not statistically significant (p = 0.3). The interobserver agreement was mostly good. CONCLUSION In the assessment of ANVGIH, the 60 keV and 70 keV VM images improved the image quality and contrast, respectively, but there was no increase in diagnostic accuracy of VM image datasets compared to linearly blended images. Hence, the diagnostic utility of DECTA in ANVGIH is still uncertain.

Abstract
The portal vein is the largest vessel supplying the liver. A number of radiological interventions are performed through the portal vein, namely for primary pathologies of the portal vein, for inducing liver hypertrophy or to treat the sequelae of portal hypertension among others. The routes used include direct transhepatic, transjugular, and, uncommonly, trans-splenic and through subcutaneous varices. Portal vein embolization and transjugular intrahepatic portosystemic shunt are among the most common portal vein interventions that are performed to induce hypertrophy of the future liver remnant and to treat complications of portal hypertension, respectively. Other interventions include transhepatic obliteration of varices and shunts, portal vein thrombolysis, portal vein recanalization, pancreatic islet cell transplantation, and embolization of portal vein injuries. We present a detailed illustrative review of the various radiological portal vein interventions.

Abstract
Mesenchymal tumors are the most common benign neoplasms of the esophagus. Owing to the rarity of these neoplasms, there is a dearth of literature regarding their diagnosis and management. Our 2-decade-long experience in managing these neoplasms surgically is presented. Relevant clinical data of all patients with esophageal mesenchymal neoplasms (EMNs) managed between January 2000 and May 2020 were retrospectively collected from a prospectively maintained esophageal diseases database in the Department of GI Surgery, AIIMS, New Delhi (India). Special emphasis was given to data pertaining to diagnostic evaluation of patients, type of surgery done (enucleation vs. resection), postoperative outcomes, histopathology and long-term follow-up. Nineteen patients (12 females; age 15-66 years) underwent surgery for EMN (mean tumor size 7.6 cm; enucleation 10; resection 9). On histopathological examination, 17 cases were noted to be benign esophageal leiomyomas and 2 were identified as gastrointestinal stromal tumors. There was no perioperative mortality. All cases were followed up for a median duration of 6 years (range 1-19 years) with no evidence of recurrence in any case. Though EMNs are uncommon, they are mostly benign, and the long-term outcomes after surgical excision are gratifying.

Abstract
Objective To study the use of serial ultrasound gastric residual volume (GRV) measurements in predicting feed intolerance in critically ill patients. Patients and methods This study was conducted in various intensive care units (ICUs) of All India Institute of Medical Sciences, New Delhi. Forty-three critically ill patients aged more than 18 years were studied for a total of 130 enteral feeding days. Gastric residual volume was obtained by calculating the antral cross-sectional area (CSA), which is the product of anteroposterior (AP) and craniocaudal (CC) diameters of gastric antrum obtained using ultrasound in the right lateral decubitus position. A baseline measurement was done before the initiation of the enteral feed and termed GRV0, the ultrasound scanning was repeated every 1 hour for the first 4 hours and termed GRV1, GRV2, GRV3, and GRV4, respectively, and the patients were watched for feed intolerance. The receiver operating characteristic (ROC) curves were constructed to correlate the GRV at each time with feed intolerance. Results The data from 43 medical and surgical critically ill patients were analyzed. Out of 130 feeding days, 13 were noted to be feed intolerant. Gastric residual volume at the end of the fourth hour of feed, that is, GRV4 was the best predictor of feed intolerance with 99.3% area under the curve (AUROC), sensitivity of 99%, specificity of 99.3%, and 95% CI, 0.89–0.98 followed by GRV3, with AUROC of 96% and sensitivity and specificity of 92.3 and 96%, respectively, with 95% CI, 0.92–0.99.

Abstract
Gastroenteropancreatic neuroendocrine neoplasms comprise a heterogeneous group of tumors that differ in their pathogenesis, hormonal syndromes produced, biological behavior and consequently, in their requirement for and/or response to specific chemotherapeutic agents and molecular targeted therapies. Various imaging techniques are available for functional and morphological evaluation of these neoplasms and the selection of investigations performed in each patient should be customized to the clinical question. Also, with the increased availability of cross sectional imaging, these neoplasms are increasingly being detected incidentally in routine radiology practice. This article is a review of the various imaging modalities currently used in the evaluation of neuroendocrine neoplasms, along with a discussion of the role of advanced imaging techniques and a glimpse into the newer imaging horizons, mostly in the research stage.

Abstract
Aggressive angiomyxoma (AA) is a rare neoplasm of mesenchymal origin. It most commonly occurs in young women, predominantly in the pelvi-perineal region. We describe a case of AA arising from the lesser curvature of the stomach in a young woman who presented with a lump in the abdomen for 6 months. The patient subsequently underwent en bloc resection of the tumour and the diagnosis was confirmed on histology. This is the first reported case of gastric origin of AA to the best of our knowledge.

Abstract
RATIONALE AND OBJECTIVES To compare dual energy CT (DECT) quantitative metrics and radiomics for differentiating benign and malignant pancreatic lesions on contrast enhanced abdomen CT. MATERIALS AND METHODS Our study included 103 patients who underwent contrast-enhanced DECT for assessing focal pancreatic lesions at one of the two hospitals (Site A: age 68 ± 12 yrs; malignant = 41, benign = 18; Site B: age 46 ± 2 yrs; malignant = 23, benign = 21). All malignant lesions had histologic confirmation, and benign lesions were stable on follow up CT (>12 months) or had characteristic benign features on MRI. Arterial-phase, low- and high-kV DICOM images were processed with the DECT Tumor Analysis (DETA) to obtain DECT quantitative metrics such as HU, iodine and water content from a region of interest (ROI) over focal pancreatic lesions. Separately, we obtained DECT radiomics from the same ROI. Data were analyzed with multiple logistic regression and receiver operating characteristics to generate area under the curve (AUC) for best predictive variables. RESULTS DECT quantitative metrics and radiomics had AUCs of 0.98-0.99 at site A and 0.89-0.94 at site B data for classifying benign and malignant pancreatic lesions. There was no significant difference in the AUCs and accuracies of DECT quantitative metrics and radiomics from lesion rims and volumes among patients at both sites (p > 0.05). Supervised learning-based model with data from the two sites demonstrated best AUCs of 0.94 (DECT radiomics) and 0.90 (DECT quantitative metrics) for characterizing pancreatic lesions as benign or malignant. CONCLUSION Compared to complex DECT radiomics, quantitative DECT information provide a simpler but accurate method of differentiating benign and malignant pancreatic lesions.

Abstract
OBJECTIVES The frequency, risk factors, and impact on survival of hemorrhage into (peri)pancreatic collections in patients with acute pancreatitis (AP) has not been well studied. The study was designed to evaluate the risk factors for hemorrhage, successful hemostasis and its effect on in-hospital mortality. METHODS In a prospective cohort study for prediction of severity of AP, the incidence, risk factors, and outcomes of pancreatic hemorrhage were analyzed. Patients with significant hemorrhage were managed according to a predefined protocol including endovascular intervention. RESULTS Out of 363 patients hospitalized during the study-period, 33(9%) patients developed hemorrhage. Median time from onset of AP to hemorrhage was 59(45-68) days. The cause of hemorrhage was arterial in 19(57.5%) patients and unlocalized in 14(42.5%) patients. Hemorrhage was managed by conservative approach in 7 (21.2%), radiographic angioembolisation in 16 (48.5%), radiographic angioembolisation followed by surgery in 3 (9.1%), and surgery in 7 (21.2%) patients. Persistent organ failure [aHR 2.3 (1.1-5.1), p = 0.03], use of large bore (>20 Fr) catheter for initial drainage [aHR 3.9 (1.7-9.1), p = 0.001] and extensive (>50%) necrosis [aHR 3.1 (1.4-6.9), p = 0.005] were significant risk factors for hemorrhage. Hemorrhage was an independent predictor of mortality [aHR 2.0 (1.2-3.4), p = 0.008] in addition to persistent organ failure (aHR 12.1 (5.7-25.8), p < 0.001). In-hospital mortality in patients with hemorrhage was 22/33 (66.7%) vs. 81/330 (25%) in no hemorrhage group [p <0.001]. CONCLUSION Pancreatic hemorrhage occurs later in the course of acute pancreatitis in relatively sicker group of patients with organ failure and extensive necrosis, and is independently associated with a higher risk of in-hospital mortality.

Abstract
AbstractDual-energy computed tomography (DECT) is an advancement in the field of CT, where images are acquired at two energies. Materials are identified and quantified based on their attenuation pattern at two different energy beams using various material decomposition algorithms. With its ability to identify and quantify materials such as fat, calcium, iron, and iodine, DECT adds great value to conventional CT and has innumerable applications in body imaging. Continuous technological advances in CT scanner hardware, material decomposition algorithms, and image reconstruction software have led to considerable growth of these applications. Among all organs, the liver is the most widely investigated by DECT, and DECT has shown promising results in most liver applications. In this article, we aim to provide an overview of the role of DECT in the assessment of diffuse liver diseases, mainly the deposition of fat, fibrosis, and iron and review the most relevant literature.

Abstract
AbstractCronkhite–Canada syndrome is a rare non-hereditary disease characterized by gastrointestinal hamartomatous polyposis and protein-losing enteropathy. The presenting symptoms are onychodystrophy, skin pigmentation, alopecia, weight loss, and diarrhea. Diagnosis is suggested by a combination of clinical, imaging, and endoscopy findings, and histology is necessary for confirmation. Here we describe a case of a 54-year-old man presenting with watery diarrhea, colicky abdominal pain, nasal obstruction, and weight loss for 6 months. Endoscopy showed multiple polyps in the stomach, duodenum, and colon. These were seen on computed tomography (CT) enterography along with polyps in the small bowel. A final diagnosis was made after the biopsy.

Abstract
Percutaneous biliary interventions are among the commonly performed nonvascular radiological interventions. Most common of these interventions is the percutaneous transhepatic biliary drainage for malignant biliary obstruction. Other biliary procedures performed include percutaneous cholecystostomy, biliary stenting, drainage for bile leaks, and various procedures like balloon dilatation, stenting, and large-bore catheter drainage for bilioenteric or post-transplant anastomotic strictures. Although these procedures are being performed for ages, no standard guidelines have been formulated. This article attempts at preparing guidelines for performing various percutaneous image-guided biliary procedures along with discussion on the published evidence in this field.

Abstract
PURPOSE To evaluate and compare the immediate and long-term outcomes of radiological interventions for hemorrhagic complications in patients with acute and chronic pancreatitis. MATERIALS AND METHODS This retrospective study, conducted between January 2014 and June 2020, included all patients with acute and chronic pancreatitis presenting with hemorrhagic complications who underwent angiography and/or embolization. Their clinical, angiographic, and embolization details were evaluated and correlated with procedure success, complications, recurrence, and mortality. The patients were subgrouped into groups A (acute pancreatitis) and C (chronic pancreatitis), and comparisons were made. RESULTS The study included 141 patients (mean age, 36.3 ± 11.2 years; 124 men), of whom 106 patients had abnormal angiography findings and underwent embolization. Of them, group A had 50 patients (56 lesions) and group C had 56 patients (61 lesions). All the patients in group A had severe acute pancreatitis, with a mean computed tomography severity index of 7.6. The technical and clinical success rates of embolization, complications, recurrence, and long-term outcomes were not significantly different between the groups. Group A had significantly higher mortality due to sepsis and organ failure. Embolic agents did not have any significant association with complications, recurrence, and mortality. After a mean follow-up of 2 years, 72.5% of the patients were asymptomatic, and none had symptoms attributable to embolization. CONCLUSIONS Success, complications, and recurrence after embolization for hemorrhagic complications were comparable between acute and chronic pancreatitis. Acute pancreatitis was associated with significantly higher mortality. Embolic agents did not significantly influence the outcomes. None had long-term adverse effects attributable to embolization.

Abstract
Objectives: With the increasing recognition of gastrointestinal (GI) manifestation of coronavirus disease-19 (COVID-19), various abdominal imaging findings are increasingly being noted. We scoped the existing literature on the abdominal imaging findings in COVID-19. Methods: A systematic literature search was performed on PubMed, Embase, Google scholar and World Health Organization COVID-19 database. Results: 35 studies were included in the final descriptive synthesis. Among the studies reporting positive abdominal imaging findings in patients with COVID-19, majority described imaging abnormalities of the GI tract (16 studies), of which bowel wall thickening was most frequently reported. Other findings noted were abdominal imaging manifestations of bowel ischemia with thrombosis of the splanchnic vasculature, and imaging features suggestive of pancreatitis. Imaging findings suggestive of solid organ infarction were reported in nine studies. An association between imaging evidence of hepatic steatosis and COVID-19 was noted in three studies. Incidental lung base findings on abdominal imaging were noted in 18 studies, where patients presented with predominant GI symptoms. The most common finding was bilateral ground glass opacities (90.7%) with predominant multilobar (91.1%) and peripheral (64.4%) distribution. Conclusion: This systematic review provides insight into the abdominal imaging findings in patients with COVID-19. Knowledge of these imaging manifestations will not only help in further research but also will aid in curtailing transmission of the SARS-CoV-2. Further prospective studies are needed to gain better insight into the pathophysiology of these imaging manifestations. Advances in knowledge: This review highlights the abdominal imaging findings in patients with COVID-19, to gain insight into the disease pathophysiology and gear the abdominal radiologist through the pandemic.

Abstract
AbstractRadiofrequency Ablation of subcapsular lesions poses a challenge due to the risks of tumour seeding along the track, hemorrhage and lower efficacy. “No touch ablation” is a relatively novel technique used in the ablation of subcapsular HCC with good results. This technique avoids direct puncture of the tumour by inserting more than one electrodes adjacent to and outside the tumor and activating them sequentially to perform ablation. The risk of track site seeding and haemorrhage is significantly reduced. We describe a case of a subcapsular HCC in a 65-year-old female patient which was successfully treated with this novel technique.

Abstract
Transjugular liver biopsy (TJLB) is widely used in adults when percutaneous liver biopsy (PLB) is contraindicated. The authors evaluated the safety, efficacy and utility of TJLB in pediatric patients with contraindications to PLB. Twenty-three children and adolescents (13 male) underwent 24 (one patient had two separate biopsies) consecutive biopsies (TJLB) under general anaesthesia (18) or intravenous sedation (6). PLB was contraindicated because of elevated prothrombin time (PT)/international normalized ratio (INR) (˃ 15.5/1.5) in 19 (79.2%) and thrombocytopenia (< 60,000/dL) in 15 (62.5%) procedures. Derangement in both INR and platelet count were found in 12 (50%) cases. Significant ascites was present in 10 (41.7%) procedures. Technical success rate with adequate biopsy sample was 95.8% (23/24) with no major complications. A new diagnosis was established in 9 (37.5%) cases. Another 14 (58.34%) biopsies confirmed the initial diagnoses. Four cases also revealed additional information guiding overall management and prognosis. Thus, TJLB is a safe and useful procedure in children.

Abstract
AbstractThe Coronavirus disease 2019, caused by severe acute respiratory syndrome corona virus 2 (SARS-CoV-2), has evolved into a pandemic and has affected more than 130 million people globally to date and continues to infect more. The disease primarily involves the respiratory system and manifests as fever, dry cough, dyspnea, and myalgia. Nearly half of the infected patients may be asymptomatic. The real-time reverse transcriptase polymerase chain reaction (RT-PCR) performed on the blood or respiratory samples is the diagnostic test with high accuracy. Although imaging with CT is not routinely indicated in this disease, this modality may provide a quick answer and assist in making a diagnosis in certain situations. In addition, imaging with CT also aids in evaluating the progress of the disease and in prognostication. A thorough knowledge of the common findings on the CT scan helps a radiologist in suggesting a diagnosis when it is performed in unsuspected patients. In this review, we describe the common and uncommon chest findings of COVID-19 on the CT scan.

Abstract
Neuroendocrine neoplasms (NENs) are a group of neoplasms arising from the diffuse endocrine system (DES). The gastrointestinal tract (GIT) is the most common site of NEN. The WHO classification divides NEN into three broad categories viz. well-differentiated NENs, poorly differentiated NENs, and mixed neuroendocrine-non-neuroendocrine neoplasms. All GIT NEN have the potential to synthesize and secrete various bioactive substances which may lead to various clinical syndromes. The NEN may occur anywhere in the GIT and exhibit varying clinical presentation, prognosis, and metastatic potential. Further, some tumors show association with familial syndromes like multiple endocrine neoplasia type 1 and neurofibromatosis type 1. Ultrasonography, computed tomography (CT), magnetic resonance imaging, and positron emission tomography-CT are the imaging modalities useful in the diagnosis, localization, and staging of GIT NEN. Management depends on the site, size, grade, and stage of the tumor with interventional radiology playing a significant role in some cases. This imaging review describes the role of a radiologist in the management of GIT NEN.

Abstract
Hemorrhagic complications are uncommon after percutaneous transhepatic biliary drainage. The presenting features include bleeding through or around the drainage catheter, hematemesis or melena. Diagnosis requires cholangiography, CT angiography or conventional angiography. Minor venous hemorrhage is managed by catheter repositioning, clamping or upgrading to a larger bore catheter. Major vascular injuries require percutaneous or endovascular procedures like embolization or stenting. A complete knowledge of these complications will direct the interventional radiologist to take adequate precautions to reduce their incidence and necessary steps in their management. This review presents and discusses various hemorrhagic complications occurring after percutaneous transhepatic biliary drainage along with their treatment options and suggests a detailed algorithm.

Abstract
AIM To compare the technical difficulty, safety, radiation exposure and success rates between right-sided and left-sided percutaneous transhepatic biliary drainage (RPTBD and LPTBD) in patients with malignant biliary obstruction (MBO). MATERIALS AND METHODS Fifty patients (28 males, 22 females; mean age 51.78 years) with MBO were randomized to undergo either RPTBD or LPTBD during the study period between June 2016 and May 2018. The procedure time, fluoroscopy time, radiation doses to the operators and patients, technical success, clinical success, complications and effect on quality of life were evaluated and compared between the two groups. RESULTS Twenty-five patients were included in each group. The technical success was 100% in both groups. There was no significant difference between RPTBD and LPTBD groups in terms of major complications [4% and 12%, respectively; p = 0.297] and minor complications [40% and 32%, respectively; p = 0.597]. Further, the average procedure time (37.80 ± 13.07 min vs 41.04 ± 14.94 min), fluoroscopy time (5.88 ± 4.2 min vs 5.97 ± 3.8 min), radiation doses to the operator (136.84 ± 106.67 μSv vs 130.40 ± 106.46 μSv) and to the patient (8.23 ± 5.80 Gycm2 vs 11.74 ± 11.28 Gycm2) were not significantly different between the groups. Clinical success was achieved in 21 patients (84%) of RPTBD group and 17 patients (68%) of LPTBD group with no significant difference (p = 0.416) between them. CONCLUSION There was no significant difference between RPTBD and LPTBD with reference to the technique, safety, radiation dose, success rates and impact on quality of life suggesting no laterality advantage for biliary drainage in cases of MBO.

Abstract
Background Normalized iodine concentration (NIC) (ratio of iodine concentration of liver to that of aorta) of liver at delayed dual-energy CT (DECT) may reflect the amount of fibrosis based on the extent of iodine uptake. Purpose To stage liver fibrosis by using 5-minute delayed DECT and compare findings with those of transient elastography (TE), shear-wave elastography (SWE), and histologic examination. Materials and Methods This prospective study included patients with chronic liver disease who were scheduled to undergo multiphase abdominal CT and liver biopsy from January 2017 to September 2018. Fifty individuals being screened as renal donors comprised the control group. Study participants underwent TE, SWE, multiphasic DECT (including 5-minute delayed dual-energy scanning), and liver biopsy. Multiphasic DECT and SWE were performed in the control group. The NIC of the right lobe of the liver (RNIC) was compared with liver stiffness (LS) as measured with TE and SWE and with the METAVIR fibrosis stage (ranging from F0 to F4). Diagnostic performance was assessed by using areas under the receiver operating characteristic curve (AUCs). Results A total of 107 participants (mean age, 35 years ± 12 [standard deviation]; 57 men) and 50 control subjects (mean age, 47 years ± 11; 29 women) were evaluated. The RNIC showed strong correlation with METAVIR stage (Spearman ρ = 0.81, P < .001). The AUC for RNIC with each METAVIR stage ranged between 0.86 (95% CI: 0.76, 0.97) and 0.96 (95% CI: 0.92, 0.99). The cut-off value of RNIC was 0.24 (sensitivity: 85% [86 of 101 participants; 95% CI: 77%, 91%]; specificity: 83% [84 of 101 participants; 95% CI: 42%, 98%]) for stage F1 fibrosis and 0.29 (sensitivity: 84% [67 of 80 participants; 95% CI: 74%, 90%]; specificity: 81% [65 of 80 participants; 95% CI: 63%, 92%]) for stage F2 fibrosis. RNIC correlated well with LS as measured with TE and SWE (Spearman ρ = 0.60 and 0.64, respectively; P < .001). Conclusion Normalized iodine concentration of liver at 5-minute delayed dual-energy CT showed strong correlation with the histologic stages of liver fibrosis and good diagnostic performance in estimating liver fibrosis. © RSNA, 2020 Online supplemental material is available for this article.

Abstract
AbstractAn accidentally retained sponge inside the body of a patient (gossypiboma) is a rare and serious adverse event after a surgical procedure with serious medicolegal implications and complications. It is commonly associated with abdominal surgeries with cholecystectomy most commonly implicated. Whorl-like appearance or mottled translucencies and radiopaque marker on imaging is diagnostic. Transmural migration into a hollow viscous has been infrequently reported. The preferred approach for the removal of gossypiboma is surgery. However, in cases of complete transmural migration, endoscopic removal remains a viable option.

Abstract
Budd-Chiari syndrome is a vascular pathology of the liver, commonly seen in adults and uncommon in children. Most children with Budd-Chiari syndrome present with ascites, and an etiology is found in only about 50%. Ultrasonography (US) with color Doppler is the main modality used in the diagnosis. US imaging additionally guides radiologic interventions and follow-up after recanalization or shunt procedure. In this pictorial review, we illustrate the findings in pediatric Budd-Chiari syndrome as seen on B-mode and color Doppler US and describe the role of US in guiding percutaneous radiologic interventions, with a brief description of the role of US contrast agent and sonoelastography in this setting.

Abstract
Gallbladder cancer is the most common malignancy of the biliary tract. It is also the most aggressive biliary tumor with the shortest median survival duration. Complete surgical resection, the only potentially curative treatment, can be accomplished only in those patients who are diagnosed at an early stage of the disease. Majority (90%) of the patients present at an advanced stage and the management involves a multidisciplinary approach. The role of imaging in gallbladder cancer cannot be overemphasized. Imaging is crucial not only in detecting, staging, and planning management but also in guiding radiological interventions. This article discusses the role of a radiologist in the diagnosis and management of gallbladder cancer.

Abstract
Clear cell sarcoma-like tumor of the gastrointestinal tract (CCSGT) is a rare, aggressive tumor with many histological mimickers. Herein, we have documented our experience of three cases of CCSGT and reviewed the literature. The index cases were identified in male patients in their twenties, one in jejunum and two in the distal colon. Histomorphological examination revealed the characteristic heterogeneous histomorphology with patchy immunohistochemical positivity with S100 protein and negative melanocytic markers. The fluorescence in-situ hybridization test showed translocation of the EWSR1 (22q12) gene in >80% tumor cells. While one of our patients died after 2 years with lung metastasis, the other two patients are still alive on 1.5 years and 3 months follow up, respectively. CCSGT is a rare malignant tumor of the gastrointestinal tract. Although characteristic morphology, use of a judicial panel of immunohistochemical stains, and translocation study for EWSR1 gene can establish the diagnosis, experience in adjuvant therapy is still limited.

Abstract
Corrosive injury is a devastating injury which carries significant morbidity. The upper gastrointestinal tract is predominantly affected with severity ranging from mild inflammation to full thickness necrosis which may result in perforation and death. Among the complications, stricture formation is most common, causing dysphagia and malnutrition. Endoscopy has a pivotal role in the diagnosis and management, with a few shortcomings. Imaging has an important role to play. Besides radiography, there is an increasing role of CT scan in the emergency setting with good accuracy in identifying patients who are likely to benefit from surgery. Further, CT scan has a role in the diagnosis of complications. Oral contrast studies help in assessing the severity and extent of stricture formation and associated fistulous complications in the subacute and chronic phase. The scope of intervention radiology for this condition is increasing. Fluoroscopy-guided balloon dilatation, drainage of collections or mucoceles, endovascular embolization of point bleeders, placement of feeding jejunostomy and image-guided biopsy are among the procedures that are being performed. Through this review we aim to stress the role the radiologist plays in the diagnosis and follow-up of these patients and in performing radiological interventions. Besides this, we have also highlighted few salient points to help understand the pathophysiology and management of such injuries which is paramount to ensure a good long-term outcome.

Abstract
INTRODUCTION Vascular complications such as venous thrombosis (VT) and pseudoaneurysm are not uncommon in patients with chronic pancreatitis (CP). The aim of this study to was to evaluate the prevalence and risk factors for vascular complications in patients with CP. METHODS A retrospective analysis of a prospectively maintained database of patients with CP presenting from January 2002 to August 2019 was performed. Venous thrombosis and pseudoaneurysm were identified using radiological imaging, and their risk factors were identified using multivariate Cox-proportional hazards. RESULTS Of 1363 patients with CP, 166 (12.2%) had vascular complications. Isolated VT was present in 132, pseudoaneurysm in 17, and both in 17 patients. They were more commonly seen in males and alcoholic CP (ACP), and less commonly in patients with pancreatic atrophy and calcification. It involved the vessels in the closest proximity to the pancreas, VT most commonly involving the splenic vein whereas pseudoaneurysm most commonly involved the splenic artery. Alcoholic CP [odds ratio (OR) 2.1, p = 0.002], pseudocyst (OR 4.6, p < 0.001) and inflammatory head mass (OR 3.1, p = 0.006) were independent risk factors for VT, whereas ACP (OR 3.49, p = 0.006) and pseudocyst (OR 3.2, p = 0.002) were independent risk factors for pseudoaneurysm. Gastrointestinal bleed occurred in 3.5% patients, and more commonly in patients with pseudoaneurysm than VT (64.7% vs 15.9%), and in patients with ACP in comparison to other etiologies (p < 0.001). CONCLUSION Vascular complications are a common complication of CP, VT being more frequent than pseudoaneurysm. Pseudocyst and ACP are independent risk factors for the development of vascular complications.

Abstract
BACKGROUND Hepatic derangements and liver injury following the Fontan operation (FO) may progress in some cases to hepatic fibrosis (HF) and cirrhosis. The respective roles of transient elastography (TE) or FibroScan, shear wave elastography (SWE), and aspartate transaminase to platelet ratio index (APRI) in assessing liver stiffness (LS) and possible liver injury in these patients are unclear. METHODS Thirty-nine patients (31 males), mean age 11.8 ± 5.7 years, median 11 years (interquartile range: 7-14.7 years), undergoing the FO between November 2017 and December 2018 were included. Liver stiffness and HF assessment was done with TE, SWE, and APRI in the preoperative period and postoperatively at 3-, 6-, and 12-month interval. RESULTS The LS values increased over time (postoperative values at 3, 6, and 12 months) as compared to preoperative values by both FibroScan and SWE. The change in liver stiffness measurement (LSM) was statistically significant: LSM0 to LSM3 (P ≤ .0001), LSM0 to LSM6 (P ≤ .0001), and LSM0 to LSM12 (P = .001). Similarly, significant changes were observed on SWE: SWE0 to SWE3 (P ≤ .0001), SWE0 to SWE6 (P ≤ .0001), and SWE0 to SWE12 (P = .001). There was no significant change in the APRI values over time. CONCLUSION Noninvasive methods such as FibroScan and SWE may be of use to assess LS in follow-up of patients undergoing the FO for early recognition of hepatic changes.

Abstract
AbstarctThe novel coronavirus disease, known as severe acute respiratory syndrome coronavirus 2 (SARS-CoV2), has developed into a pandemic affecting more than three million people worldwide. It predominantly affects the respiratory system and patients present with fever, dry cough, dyspnea, and myalgia. The confirmatory diagnostic test is real-time reverse transcriptase polymerase chain reaction on blood or respiratory samples. Imaging with computed tomography, although not routinely recommended, may not only assist in making a diagnosis but also in assessing disease progression, assessing complications, and in prognostication. This review describes the objectives, techniques, imaging features, and reporting of computed tomography findings of SARS-CoV2 pneumonia.

Abstract
Pancake kidney is a rare renal fusion anomaly with increased risk of complications, such as stone disease and infections, due to altered urodynamics. Image-guided (ultrasonography and fluoroscopy) percutaneous nephrostomy (PCN) is performed to decompress an obstructed pancake kidney. However, routine image guidance may be unable to provide a suitable access in complex clinical scenarios. The approach for PCN in a low-lying fused kidney is difficult due to a limited safe posterior retroperitoneal paraspinal route, and anterior transperitoneal approach poses risks of urine leak and peritonitis. We report a case of an obstructed pancake kidney managed by CT-guided PCN through a transiliopsoas approach.

Abstract
Endoscopic retrograde cholangiopancreatography (ERCP) has currently become an inseparable tool in the gastroenterologist's armamentarium for treatment of pancreaticobiliary disorders. Given the increase in number of therapeutic ERCP procedures today, the need for prompt and correct diagnosis of its complications is pivotal. This review discusses the mechanisms, risk factors, imaging findings and general management aspects of common and rare complications of ERCP. Furthermore, the review elaborates on imaging indications, recommended protocol and normal imaging findings post ERCP.

Abstract
Differentiating Crohn’s disease (CD) and intestinal tuberculosis (ITB) has remained a dilemma for most of the clinicians in the developing world, which are endemic for ITB, and where the disease burden of inflammatory bowel disease is on the rise. Although, there are certain clinical (diarrhea/hematochezia/perianal disease common in CD; fever/night sweats common in ITB), endoscopic (longitudinal/aphthous ulcers common in CD; transverse ulcers/patulous ileocaecal valve common in ITB), histologic (caseating/confluent/large granuloma common in ITB; microgranuloma common in CD), microbiologic (positive stain/culture for acid fast-bacillus in ITB), radiologic (long segment involvement/comb sign/skip lesions common in CD; necrotic lymph node/contiguous ileocaecal involvement common in ITB), and serologic differences between CD and ITB, the only exclusive features are caseation necrosis on biopsy, positive smear for acid-fast bacillus (AFB) and/or AFB culture, and necrotic lymph node on cross-sectional imaging in ITB. However, these exclusive features are limited by poor sensitivity, and this has led to the development of multiple multi-parametric predictive models. These models are also limited by complex formulae, small sample size and lack of validation across other populations. Several new parameters have come up including the latest Bayesian meta-analysis, enumeration of peripheral blood T-regulatory cells, and updated computed tomography based predictive score. However, therapeutic anti-tubercular therapy (ATT) trial, and subsequent clinical and endoscopic response to ATT is still required in a significant proportion of patients to establish the diagnosis. Therapeutic ATT trial is associated with a delay in the diagnosis of CD, and there is a need for better modalities for improved differentiation and reduction in the need for ATT trial.

Abstract
Carcinoid tumor of the mesentery has a classical imaging morphology. A specific diagnosis can often be provided on the basis of clinical history, elevated serum neuroendocrine markers, and uptake on somatostatin receptor-based radiotracer studies. Although a number of inflammatory and neoplastic conditions may mimic carcinoid tumor on many of these modalities, uptake on 68Ga-DOTANOC positron emission tomography/computed tomography (PET/CT) is considered specific. We report a case of a 28-year-old male presenting with a mesenteric mass along with elevated serum neuroendocrine markers and uptake on DOTANOC PET/CT, all suggestive of carcinoid tumor. However, the histopathologic examination after surgical resection revealed necrotizing granulomas consistent with tuberculosis (TB). This case highlights the great masquerader that TB can be and stresses the importance of keeping a high index of suspicion for TB, especially in endemic areas.

Abstract
OBJECTIVE: To assess the accuracy of splenic stiffness (SS) measured by 2D-shear wave elastography (SWE) for predicting variceal bleeding in the patients with extrahepatic portal vein obstruction (EHPVO). METHODS: 52 patients with EHPVO (mean age: 22.29 years; 26 each males and females) were included in the study after obtaining approval from the institute ethics committee. All patients initially underwent upper gastrointestinal endoscopy followed by ultrasonography, including 2D-SWE on the Aixplorer Supersonic Imagine scanner. The SS was measured through the anterior abdominal wall and an average of three measurements was taken. The SS was then compared with clinical symptoms, variceal grade, and other ultrasonography (USG) parameters. USG parameters were also compared with variceal grade. RESULTS: The mean SS was 44.92 ± 12.35 kPa. There was no significant difference in the mean SS of patients with high grade varices (44.30 kPa; n = 25) from those with low grade varices (46.91 kPa; n = 20). The ROC analysis showed a poor area under the curve of 0.477 for the prediction of high grade varices by the SS. The SS did not show any significant correlation with other ultrasonography parameters except splenic size, with which there was a weak but significant correlation. The measurement of SS by 2D-SWE was reliable and Cronbach's alpha was 0.905. CONCLUSION: The SS measured by 2D-SWE is not an accurate predictor of variceal grade and thus bleeding in patients of EHPVO. ADVANCES IN KNOWLEDGE: EHPVO is a vascular pathology with most patients showing splenomegaly and preserved liver function. Although, elastography of spleen has been shown to be useful in patients with cirrhosis for predicting portal hypertension, it does not seem to be helpful in patients with EHPVO.

Abstract
CONTEXT Cysts arising from the hepatobiliary tree are a group of heterogeneous lesions with regard to pathogenesis, clinical presentation, and radiological finding. They can be intrahepatic or extrahepatic, developmental, secondary to infective/inflammatory etiologies, as well as neoplastic. This study was conducted to determine the spectrum of hepatobiliary cysts in surgically intervened cases, with regard to their prevalence, histological spectrum, and clinicoradiological correlation, wherever possible. METHODS In this retrospective observational study, hematoxylin and eosin stained slides of all cases of hepatobiliary cystic lesions, operated between 2009 and 2016 were reviewed. Special stains as reticulin, Masson's trichrome, and periodic acid Schiff were done wherever necessary. Overall prevalence, age-sex distribution, clinical presentation and histopathological patterns were studied. Relevant imaging findings were correlated wherever possible. RESULTS A total of 312 cases of hepatobiliary cysts were identified, the majority in females. Choledochal cysts (CCs) were the most common type (n = 198,63.5%), followed by hydatid cysts (n = 73,23.3%), simple hepatic cysts (n = 10,3.2%), congenital hepatic fibrosis (n = 10,3.2%), biliary cystadenomas (n = 4,1.2%) hepatic mesenchymal hamartomas (n = 7,2.2%), and cavernous hemangiomas (n = 3,0.9%). Fibropolycystic liver disease (n = 2,0.6%), Caroli's disease (n = 1, 0.3%), liver abscess (n = 2, 0.6%), infantile hemangioendothelioma (n = 1,0.3%), and biliary cystadenocarcinomas (n = 1,0.3%) were rare. Lesions noted mostly in 1st decade of life were: CCs, fibrocystic liver disease, Caroli's syndrome, cystic mesenchymal hamartoma, and infantile hemangioendotheliomas. CONCLUSION In our cohort of surgically intervened cases of hepatobiliary cystic lesions from a tertiary care hospital in North India, the CCs, followed by hydatid cyst were the most common lesions. Histology can play vital role in characterization, as often clinical findings and radiology can overlap.

Abstract
Massive gastrointestinal bleeding after corrosive intake is a rare complication that generally mandates a surgical intervention for control. Angioembolization for control of gastrointestinal bleeding in the setting of acute corrosive injury has not been described. Here, we present our experience of a case of acute corrosive injury presenting with massive upper gastrointestinal bleeding in the delayed phase which was successfully managed by angioembolization. We discuss the case in light of the literature available and describe markers which may serve to identify potential candidates for angioembolization.

Abstract
BACKGROUND The literature on disease characteristics of colonic Crohn's disease (CD) is sparse, especially from Asia, where the burden of inflammatory bowel disease is on the rise. The present study aims to describe the disease characteristics of colonic CD, and compare it with that of ileal/ileocolonic disease. METHODS This retrospective study included adult patients of CD (diagnosed by standard criteria, follow-up duration > 6 months) on follow-up between August 2004 and January 2016. The disease location was classified by Montreal classification. The data were recorded on demographic characteristics, smoking status, disease phenotype, disease course, treatment received, hospitalization and surgeries. RESULTS Of 406 CD patients, 123 had colonic [mean age (at onset) 30.4 ± 13.2 years, 59.3% males] and 265 had ileal/ileocolonic disease [mean age (at onset) 32.9 ± 13.8 years, 61.5% males] while 18 patients had isolated upper GI disease. The frequency of inflammatory behavior (B1 phenotype; 61.8 vs. 46.4%, p = 0.003), perianal disease (23.6 vs. 4.5%, p < 0.001), and extra-intestinal manifestation (42.3 vs. 30.2%, p = 0.019) was higher in colonic than ileal/ileocolonic CD. Though not statistically significant, requirement of atleast one course of steroid was lower in colonic CD (72.7 vs. 84.2%, p = 0.098). Although there was no difference in the frequency of hospitalization (30.1 vs. 27.1%, p = 0.45), the overall requirement for surgery was significantly lower in colonic CD (17.1 vs. 26.1%, p = 0.032) and patients with colonic disease had a lower cumulative probability of first surgery in the first 10 years of follow-up [Hazard ratio 0.556 (95% CI 0.313-0.985), p = 0.045]. CONCLUSION Colonic CD was associated with less aggressive disease behavior and lower requirement of surgery as compared to ileal/ileocolonic CD.
