“…A standard technique of examination (SAMPLE et coll. 1975, CARLSEN & FILLY 1976, DOUST & PEARCE 1976, WEILL et coll. 1977) was employed including transversal, lon gitudinal, and oblique scans, sometimes with the transducer angled about 10° caudally or cranially in an effort to avoid bowel gas.…”

Ultrasound and angiography of the pancreas were performed in 68 patients. Ultrasound reached an accuracy of 64.5 per cent and angiography 76.4 per cent. Both methods excluded disease of the gland in all patients without clinical evidence of disease at follow-up. Both methods had higher accuracy in the diagnosis of carcinoma than of pancreatitis. Although angiography has higher accuracy, ultrasound is recommended for screening of patients with abdominal pain. Because of the differential diagnostic difficulties, percutaneous fine-needle biopsy is recommended, when a pancreatic lesion is demonstrated. Angiography is used mainly to predict operability and prognosis.

With the advent of new gray scale imaging techniques, ultrasound plays a major role in the diagnosis of pancreatic lesions. As a noninvasive, nonionizing, accurate, and inexpensive diagnostic modality that directly images the pancreatic gland, ultrasound can be used as a primary screening tool. It is helpful in confirming the diagnosis of acute pancreatitis and in detecting and following pseudocysts and other complications. Neoplasms can be detected with a high rate of accuracy, and by assessing the presence of ascites or metastatic foci in the liver, ultrasound can aid in the staging of the neoplastic process. Bowel gas and obesity remain serious limitations to adequate examination, and in these patients computed tomography offers a complementary modality.

“…The normal hepatic and portal veins are visible within the parenchyma of the liver on virtually all ultrasonograms. By virtue of their differing anatomic courses, one can readily distinguish these vessels from one another (4). Normal-sized intrahepatic bile ducts are usually not visible, although the normal extrahepatic biliary tract can be visualized not uncommonly (5).…”

Ultrasonographic identification of dilated intrahepatic bile ducts and their differentiation from portal venous structures

The appearance of dilated intrahepatic bile ducts was evaluated on ultrasonograms of 50 patients with proven extrahepatic biliary obstruction. Five characteristic changes allowed differentiation between biliary and portal venous systems. These changes included: 1) alteration in the anatomic pattern adjacent to the main right portal venous segment and the main portal vein bifurcation. 2) Irregular walls of dilated bile ducts. 3) Stellate confluence of dilated bile ducts. 4) Acoustic enhancement by dilated bile ducts. 5) Peripheral location of dilated bile ducts. Many patients exhibited more than one of these findings. Parasagittal scans of the main right portal vein were the most sensitive for detection of intrahepatic ductal dilatation. Recognition of the characteristic changes and knowledge of the portal venous anatomy makes it possible to diagnose extrahepatic biliary obstruction with a high degree of confidence.
