Imaging is vital for assessing pancreaticobiliary diseases....
The aim of the study was to investigate the spectrum and pattern of pancreaticobiliary diseases in adult Nigerians using magnetic resonance cholangiopancreatography (MRCP)....
This was a retrospective, descriptive cross-sectional study. The electronic radiological records of 110 adult Nigerians who had undergone MRCP were reviewed. The MRCP images were evaluated for bile du...
There were 45 males (40.9%) and 65 females (59.1%) aged 18-83 years, with a mean age of 51.93 ± 15.22 years. Jaundice (59.1%) and right hypochondrial pain (31.8%) were the most common presenting compl...
Gallstones were the predominant pathology of the various pancreaticobiliary diseases, while Pancreatic head and gallbladder carcinoma were the most common malignant diseases....
Acute cholecystitis is one of the most prevalent surgical abdominal conditions. The Tokyo Guidelines describe the management of acute cholecystitis and recommend bailout procedures for "difficult" cho...
This retrospective cohort study was conducted at a single center between January 2017 and December 2021. Patients who underwent laparoscopic cholecystectomy for acute cholecystitis were enrolled and c...
In total, 161 patients who underwent laparoscopic cholecystectomy for acute cholecystitis were reviewed. Fourteen were excluded because of a lack of preoperative magnetic resonance cholangiopancreatog...
In this study, defect of the cystic duct in the magnetic resonance cholangiopancreatography can predict conversion to bailout procedures. To the best of our knowledge, this is the first report to desc...
This study aimed to develop an automated segmentation system for biliary structures using a deep learning model, based on data from magnetic resonance cholangiopancreatography (MRCP)....
Living liver donors who underwent MRCP using the gradient and spin echo technique followed by three-dimensional modeling were eligible for this study. A three-dimensional residual U-Net model was impl...
The study incorporated 250 cases. There was no difference in the baseline characteristics between the train set (n=225) and test set (n=25). The overall mean Dice Similarity Coefficient was 0.80±0.20 ...
The developed automated segmentation model for biliary structures, utilizing MRCP data and deep learning techniques, demonstrated robust performance and holds potential for further advancements in aut...
Respiratory-triggered (RT) and breath-hold are the most common acquisition modalities for magnetic resonance cholangiopancreatography (MRCP). The present study compared the three different acquisition...
Three MRCP acquisition modalities were used in this study: conventional respiratory-triggered sampling perfection with application-optimized contrasts using different flip evolutions (RT-SPACE), modif...
There was a significant difference in the mean acquisition time among conventional RT-SPACE, modified RT-SPACE, and BH-SPACE (167.41±32.11 seconds vs 50.84±73.78 seconds vs 18.00 seconds,...
MRCP acquisition with the modified RT-SPACE sequence greatly shortens the acquisition time with comparable quality images. The MRCP acquisition modality could be designed based on the patient's situat...
Magnetic resonance cholangiopancreatography (MRCP) is commonly used in humans and is also feasible in cats. The aim of this post-mortem study was to investigate the feasibility of MRCP in eight adult ...
AIDS cholangiopathy is a rare condition characterized by intra- and extra-hepatic ductal strictures causing biliary obstruction primarily in individuals with advanced HIV infection and low clusters of...
The breath-hold (BH) 3D magnetic resonance cholangiopancreatography method has been reported to suppress "respiratory artifacts"; however, the influence of gastrointestinal peristalsis around the targ...
Magnetic resonance cholangiopancreatography (MRCP) may exhibit ghosting and blurring artifacts due to irregular breathing cycles, which can be overcome by shortening the shot duration. T2 preparation ...
To evaluate the clinical usefulness of TPT-MRCP in both navigation and breath-hold sequences compared to the conventional method....
We obtained navigation MRCP, which were TPT and conventional 3D turbo spin-echo in 37 patients, and breath-hold MRCP in 31 patients, which were TPT and gradient and spin echo. The quantitative evaluat...
TPT-MRCP was significantly superior to conventional MRCP in all quantitative evaluations, except for signal-to-noise ratio in the navigation sequence. In the visual evaluation, TPT-MRCP provided highe...
TPT-MRCP provides higher image quality than conventional techniques in both navigation and breath-hold sequences. The present study demonstrates the greater clinical usefulness of TPT-MRCP....
To develop an auto-categorization system based on machine learning for three-dimensional magnetic resonance cholangiopancreatography (3D MRCP) to detect choledocholithiasis from healthy and symptomati...
3D MRCP sequences from 254 cases with common bile duct (CBD) stones and 251 cases with normal CBD were enrolled to train the 3D Convolutional Neural Network (3D-CNN) model. Then 184 patients from thre...
With a cutoff value of 0.2754, 3D-CNN achieved the sensitivity, specificity, and accuracy of 94.51%, 92.47%, and 93.48%, respectively. In the receiver operating characteristic curve analysis, the area...
An artificial intelligence-assisted diagnostic system for CBD stones was constructed using 3D-CNN model for 3D MRCP images. The performance of 3D-CNN model was comparable to that of radiologists in di...
Magnetic resonance cholangiopancreatography (MRCP) is an imaging technique that has advanced over the past few years. It still plays a crucial role in the study of numerous pancreaticobiliary diseases...
This study involved a total of 90 participants, distributed evenly among three groups, with each group comprising 30 patients. Negative oral contrast solutions containing paramagnetic substances like ...
The in vitro evaluation of the solutions showed that date syrup and hematinic syrup were hypointense in T2W sequences. The images obtained showed no significant difference in the CNR between the three...
Pineapple juice was the best contrast agent. However, date syrup and hematinic syrup can also be used to improve the imaging quality....
