To evaluate the diagnostic potential of spiral computed tomography (CT) performed after the administration of cholangiographic contrast material (spiral CT cholangiography) in patients with suspected obstructive biliary disease.
After infusion of meglumine iodoxamate, 29 patients underwent upper abdominal spiral CT with subsequent three-dimensional rendering of the biliary tract. In 27 patients, the presence, site, and extent of biliary obstruction were compared with that at endoscopic retrograde cholangiography (ERC).
Spiral CT cholangiography correctly depicted biliary obstruction in 14 of 27 patients, with no false-positive or false-negative cases. In one patient, the precise length of a common bile duct stenosis could not be assessed with spiral CT cholangiography. ERC demonstrated intrahepatic ductal stenoses more clearly in two patients. In two patients with hilar cholangiocarcinomas, spiral CT cholangiography depicted undrained areas not seen with ERC.
Spiral CT cholangiography allows accurate assessment of the biliary system in patients with suspected obstructive biliary disease.
评估在疑似梗阻性胆道疾病患者中，胆管造影对比剂注射后行螺旋计算机断层扫描（CT）（螺旋CT胆管造影）的诊断潜力。
静脉注射碘番酸葡甲胺后，29例患者接受上腹部螺旋CT检查，随后对胆道进行三维重建。在27例患者中，将胆道梗阻的存在、部位及范围与内镜逆行胆管造影（ERC）的结果进行比较。
27例患者中，螺旋CT胆管造影正确显示了14例患者的胆道梗阻，无假阳性或假阴性病例。1例患者中，螺旋CT胆管造影无法评估胆总管狭窄的准确长度。ERC在2例患者中更清晰地显示了肝内胆管狭窄。在2例肝门部胆管癌患者中，螺旋CT胆管造影显示了ERC未发现的引流不畅区域。
螺旋CT胆管造影能够准确评估疑似梗阻性胆道疾病患者的胆道系统。
