The multiplanar capability of spiral CT improves the evaluation of bile duct lesions. In particular, spiral CT after intravenous administration of a cholangiographic agent (spiral CT cholangiography) provides adequate 2D and 3D images of the bile ducts in patients with normal bilirubin levels. Spiral CT cholangiography may be particularly useful as a noninvasive imaging method to detect biliary anatomic variations and bile duct stones before or after laparoscopic cholecystectomy. This technique does not replace retrograde cholangiography which has therapeutic applications, but might help to select patients who need to undergo invasive procedures such as retrograde cholangiography.
螺旋CT的多平面成像能力提高了胆管病变的评估水平。特别是，静脉注射胆管造影剂后的螺旋CT（螺旋CT胆管造影）能为胆红素水平正常的患者提供足够的胆管二维和三维图像。螺旋CT胆管造影作为一种非侵入性成像方法，在腹腔镜胆囊切除术之前或之后检测胆道解剖变异和胆管结石可能特别有用。这项技术并不能取代具有治疗作用的逆行胆管造影，但可能有助于选择需要接受逆行胆管造影等侵入性检查的患者。
