Abstract:
Thirty-three patients with suspected biliary obstruction were prospectively evaluated with multislice CT cholangiography using thin-slab minimum intensity projection (MinIP) and multiplanar reformation (MPR) to determine its usefulness and to compare with the comparative studies of endoscopic retrograde cholangiography (ERC), magnetic resonance cholangiography (MRC), or percutaneous transhepatic cholangiography (PTC). CT cholangiography made correct diagnoses in all biliary obstructions except in two patients with common bile duct stones. The correspondence with the comparative study was 93.9%. Multislice CT cholangiography may be favorable in noninvasive evaluation of biliary obstructions.

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
