What Student Need To Know About Imaging for Hepato-Biliary-Pancreatic System In Radio Diagnosis.

In recent years, newer techniques have become available to the clinician for the diagnosis and treatment of biliary and pancreatic disease. Ultrasound remains the first-line imaging tool for investigation of suspected biliary obstruction; however, recent advances in MRI have changed practice, and ERCP in patients with biliary disease is increasingly reserved for therapeutic purposes. Biliary imaging often requires a multimodality approach. Irrespective of imaging technique, an appreciation of the pathologic basis of biliary disease, combined with careful inspection of the imaging appearances, is vital for the correct interpretation of biliary studies. As a nonoperative procedure, endoscopic ultrasound (EUS) can accurately locate and locally stage pathology of the pancreas and periampullary region and even provide reliable biopsy evidence in experienced hands. A limitation, of course, is its field-of-view restriction, which prevents identification of distant metastatic disease. This restriction is not prese
