AI Article Synopsis
- The study evaluated the effectiveness of 5.0 T MRI for MR Cholangiopancreatography (MRCP) imaging against 3.0 T, specifically looking at visualization detail, signal-to-noise ratio (SNR), and image artifacts.
- Both healthy subjects and those with biliary dilation were examined with both MRI machines, revealing that the 5.0 T MRI provided significantly better visualization of the biliary tree branches, although SNR and image artifacts were similar in both machines.
- Overall, while the 5.0 T MRI showed enhanced detail in biliary imaging, its performance in terms of SNR and artifacts was comparable to that of the 3.0 T MRI.
Article Abstract
Background: This study aimed to assess the feasibility and performance of 5.0 T MRI in MR Cholangiopancreatography (MRCP) imaging compared to 3.0 T, focusing on detail visualization, signal-to-noise ratio (SNR), and image artifacts.
Methods: A prospective study from May to October 2023 involved 20 healthy subjects and 19 with biliary dilation. Both groups underwent MRCP using 3.0 T and 5.0 T scanners. The detail visualization capability of the biliary tree and the SNR of the images were quantitatively evaluated. Two experienced MRI diagnostic physicians assessed the image artifacts qualitatively on a scale of 1 to 5. The t-test or Wilcoxon signed-rank test compared the quantitative results of biliary visualization and SNR between 3.0 T and 5.0 T scanners, while the Wilcoxon signed-rank test was used for comparing the level of image artifacts between the two scanners. The inter reader consistency was tested using Kappa test.
Results: In both healthy subjects and those with biliary dilation, the 5.0 T group exhibited significantly higher numbers of biliary tree branches, along with greater total and maximum branch lengths, compared to the 3.0 T group (P<0.05). Although the maximum branch length was higher in the 5.0 T group among healthy subjects, this difference was not statistically significant (P = 0.053). No notable differences were observed in SNR and image artifact levels between the two groups across both field strengths (P>0.05).
Conclusions: MRCP at 5.0 T offers superior biliary tree visualization compared to 3.0 T. The performance regarding SNR and image artifacts between the two is relatively comparable.

Laparoscopic cholecystectomy for triple gallbladder malformation: A comprehensive case report and literature review.
Medicine (Baltimore)
January 2025
Hepatobiliary Surgery, Hepatobiliary Disease Laboratory, Kailuan General Hospital, Tangshan, Hebei Province, China.
Rationale: Triple gallbladder is a rare congenital anatomical abnormality because of the incomplete regression of rudimentary bile ducts and is often not found until it is accidentally detected during imaging research.
Patient Concerns: We report a rare case of triple gallbladder malformation and review the English literature on biliary tract variation caused by gallbladder malformation. The diagnosis, treatment, and postoperative situation of the patients were summarized and analyzed.
Exploring the effects of gut microbiota on cholangiocarcinoma progression by patient-derived organoids.

Department of Psychiatry and Psychotherapy, University Medical Center Mainz, 55131, Mainz, Germany.
Background: Recent research indicates a role of gut microbiota in development and progression of life-threatening diseases such as cancer. Carcinomas of the biliary ducts, the so-called cholangiocarcinomas, are known for their aggressive tumor biology, implying poor prognosis of affected patients. An impact of the gut microbiota on cholangiocarcinoma development and progression is plausible due to the enterohepatic circulation and is therefore the subject of scientific debate, however evidence is still lacking.

Background: Gallbladder and biliary diseases (GABD) represent prevalent disorders of the digestive system.
Methods: Data on age-standardized incidence rate (ASIR), age-standardized mortality rate (ASMR), and age-standardized disability-adjusted life years (DALYs) rate (ASDR) were extracted from the Global Burden of Disease (GBD) 2021 study. The estimated annual percentage change (EAPC) was utilized to quantify temporal trends in GABD.
Subcutaneous adipose tissue radiodensity as a predictor of poor prognosis in advanced biliary tract cancer.
J Hepatobiliary Pancreat Sci
January 2025
Department of Gastroenterology and Hepatology, Hokkaido University Hospital, Sapporo, Japan.
Background: High subcutaneous adipose tissue radiodensity (SATr), an indirect surrogate marker of adipose tissue quality, was associated with poor prognosis in various cancers. The present study aimed to assess the association of SATr with survival outcomes in patients with advanced biliary tract cancer (BTC).
Methods: This retrospective, single-center study included patients with unresectable or recurrent BTC who underwent chemotherapy/chemoradiotherapy.
