Radiological Imaging In Liver Diseases
1. Magnetic resonance cholangiopancreatography (MRCP) is a sensitive, noninvasive method of detecting bile duct stones, strictures, and dilation;
2. MRCP less reliable than ERCP for distinguishing malignant from benign strictures. ERCP is used to demonstrate pancreatic or ampullary causes of jaundice to carry out papillotomy and stone extraction, or to insert a stent through an obstructing lesion.
3. Complications of ERCP include pancreatitis, cholangitis, bleeding, or duodenal perforation after papillotomy.
4. Percutaneous transhepatic cholangiography (PTC) is an alternative approach to evaluating the anatomy of the biliary tree.
5. Dilated bile ducts by ultrasonography or CT scan indicates biliary obstruction (90-95%) sensitivity).
6. MRI is the most accurate technique for identifying isolated liver lesions such as hemangiomas, focal nodular hyperplasia, or focal fatty infiltration and for detecting hepatic iron overload.
7. Dynamic gadolinium enhanced MRI and administration of super paramagnetic iron oxide visualizes hepatic fibrosis.
8. Endoscopic ultrasonography is the most sensitive test for detecting small lesions of the ampulla or pancreatic head and for detecting portal vein invasion by pancreatic cancer. It is also accurate in detecting or excluding bile duct stones.
9. Hepatic angiography is now rarely needed, as both CT and MRI technology is able to characterize hepatic vasculature (arterial and venous). But may be necessary to image the hepatic veins further in patient with suspected hepatic venous outflow obstruction (Budd-Chiari)
