Background: To resolve drawbacks of navigator triggering (NT) three-dimensional (3D) magnetic resonance cholangiopancreatography (MRCP), several approaches were proposed to obtain 3D MRCP within a single breath-hold (BH). However, reduced field-of-view technique in the phase-encoding direction combined with two-dimensional spatially selective radiofrequency excitation pulses has not yet been applied to 3D BH MRCP.
Purpose: To investigate the feasibility and the complementary value of 3D BH zoomed MRCP to conventional 3D NT MRCP in patients with branch duct intraductal papillary mucinous neoplasms (BD-IPMNs) of the pancreas.
Study Type: Retrospective.
Population: A total of 221 patients (116 male and 105 female, median age 73 years) with BD-IPMNs.
Field Strength/sequence: 3.0 T/3D turbo spin echo ASSESSMENT: MR images were analyzed by three radiologists (R.M., H.O., M.T., with 1, 13, and 17 years of experience) to compare blurring and motion artifacts, background suppression, visualization of main pancreatic duct (MPD), conspicuity of BD-IPMN, and overall image quality.
Statistical Tests: Wilcoxon-signed rank, Mann-Whitney U, chi-squared or Fisher's exact tests (P < 0.05).
Results: Image quality was significantly higher on 3D NT MRCP images than on 3D BH zoomed MRCP (median (interquartile range); background suppression, 4 (4-4) vs. 3 (3-4); visualization of MPD, 4 (3-4) vs. 4 (3-4), conspicuity of BD-IPMN, 4 (3-4) vs. 3 (3-4); and overall image quality, 3 (3-4) vs. 3 (3-3)). However, in 32 (14%) patients, 3D NT MRCP showed a score of 1 or 2 in overall image quality. Regarding the conspicuity of BD-IPMN, a conspicuity score of 1 or 2 was rendered in 31 (14%) patients in 3D NT MRCP group. Conversely, 3D BH zoomed MRCP showed a score of 3 or 4 in 29 (94%) of these 31 patients.
Data Conclusion: 3D BH zoomed MRCP plays a complementary role to 3D NT MRCP, and may improve the conspicuity of BD-IPMNs in patients with irregular breathing pattern.
Level Of Evidence: 4 TECHNICAL EFFICACY: Stage 2.

Background And Aims: Pancreas divisum (PD) is the most common developmental anatomic variant of pancreatic duct. The published data on the accuracy of the detection of pancreas divisum by linear-array endoscopic ultrasound (L-EUS) is limited. The current study aimed to assess the diagnostic accuracy of L-EUS compared with magnetic resonance cholangiopancreatography (MRCP) for identifying PD.

Biliary and peribiliary cystic lesions represent a diverse group of abnormalities, often discovered incidentally during imaging for unrelated conditions. These lesions, typically asymptomatic, necessitate precise imaging modalities to characterize their nature and determine subsequent clinical actions, such as follow-up imaging, biopsy, or surgical referral. The anatomic location of these cystic lesions, whether biliary or peribiliary, influences both diagnostic and prognostic outcomes.

We present a rare and challenging case of Weil's disease in a patient who was admitted to the Critical Care Unit with a clinical suspicion of the condition. The patient showed a prompt response to treatment before laboratory confirmation was obtained. Leptospirosis, a zoonotic disease, is most commonly found in tropical and temperate regions.

Introduction And Importance: One of the very rare causes of obstructive jaundice, Lemmel's syndrome, is caused due to biliary mechanical compression by a juxtapapillary diverticulum. It is defined as obstructive jaundice due to juxtapapillary diverticulum in the absence of cholelithiasis, periampullary tumours, or other detectable obstacles. It is an extremely rare syndrome; therefore, studies need to be done for proper diagnosis and management.

Background: The management of Type III sphincter of Oddi dysfunction or functional biliary pain (FBP) is challenging. A strategy of intermittent intrasphincteric botulinum toxin (Botox) injections into the sphincter of Oddi can alleviate pancreaticobiliary pain. In patients who lose response to intermittent Botox injections, endoscopic biliary sphincterotomy (ES) could potentially reset pain facilitating ongoing management of symptoms.
