2024年7月5日 · The common bile duct is supplied by a network of arteries from several sources: from above: right hepatic artery and cystic artery. from below: posterior superior pancreaticoduodenal artery, retroduodenal artery, and retroportal artery. Variant anatomy. There are four main relationships of the CBD with the pancreatic head 2:

2009年10月1日 · Identification of bile duct wall thickening raises concern for cholangitis or malignancy. Improved diagnosis of biliary disease can be achieved with a knowledge of the benefits and limitations of modern MR and CT cholangiographic techniques, including the use of biliary-excreted contrast material and of various postprocessing techniques.

Healthcare providers use magnetic resonance cholangiopancreatography (MRCP), a contrast MRI, to diagnose pancreatic cancer, pancreatitis, gallstones and bile duct problems. An MRI scanner takes images as an IV dye travels through the pancreatic and biliary systems. It’s less invasive than an endoscopic retrograde cholangiopancreatography (ERCP).

2023年12月9日 · Medical professionals utilize various imaging techniques, including ultrasound, CT scans, and MRIs, to diagnose and treat conditions related to the dilated common bile duct. Timely identification and treatment of the underlying cause can prevent complications and ensure a better prognosis for individuals experiencing a dilated common bile duct.

2024年9月21日 · Magnetic resonance cholangiopancreatography (MRCP) is a non-invasive imaging technique to visualize the intra and extrahepatic biliary tree and pancreatic ductal system. It can provide diagnostically-equivalent images to ERCP and is a useful technique in high risk patients to avoid significant morbidity.

2024年10月2日 · Atlas of anatomy of the intra and extrahepatic biliary tree, the common bile duct (PBC, Ductus choledocus), the gallbladder and pancreatic ductal system (duct of Wirsung) on MRI (MR cholangiopancreatography)

2016年9月9日 · Magnetic resonance cholangiopancreatography (MRCP) is highly accurate in delineating bile duct anatomy for presurgical planning and is useful in determining whether variant anatomy exists, which may pose an increased risk of injury to the bile ducts during surgery [4]. Accessory bile ducts are aberrant ducts that drain individual liver segments.

2020年9月1日 · MRCP depicts biliary ducts and extraductal disease well when combined with T1- and T2-weighted imaging, but the radiologist must be aware of possible anatomic variations to avoid misinterpretation of imaging findings.

Coronal MRCP image showing aberrant opening of right posterior sectoral duct into common bile duct (arrow). High insertion of cystic duct is seen opening at the confluence (arrowhead) Cystic duct variations. Variations in cystic duct insertion are also frequently seen.

Our study provides normative measurements for the common bile duct and pancreatic duct for children up to age 10 years. The upper limits of the CBD and pancreatic duct increase with age, and the values range 1.1-4.0 mm for the CBD and 0.6-1.9 mm for the pancreatic duct.
