To evaluate prospectively a non-breath-hold magnetic resonance (MR) cholangiographic technique.
Twenty-nine non-breath-hold, heavily T2-weighted, turbo spin-echo MR cholangiograms were obtained in 28 patients and compared with 28 direct cholangiographic studies in 24 patients.
MR cholangiography showed the intrahepatic ducts (IHDs) within the peripheral third of the liver and within the four hepatic segments in 100% of cases with dilated ducts. IHDs were seen in the peripheral third in 82% of cases with nondilated ducts and within the four hepatic segments in 91%. The extrahepatic duct (EHD), dilated and nondilated, was visualized in 90% of cases. Filling defects were identified in the EHD in 71% of cases and in the gallbladder in 100%. All obstructions were identified and their site and character accurately shown in most cases. The presence of IHD dilatation was accurately shown, and estimates of EHD and main pancreatic duct caliber correlated closely with those of direct cholangiography.
Non-breath-hold MR cholangiography is a reliable method for depiction of the biliary system.
前瞻性评估一种非屏气磁共振（MR）胆管造影技术。
对28例患者进行了29次非屏气、重T2加权、快速自旋回波MR胆管造影，并与24例患者的28次直接胆管造影研究进行比较。
MR胆管造影在100%的胆管扩张病例中显示了肝外周三分之一及四个肝段内的肝内胆管（IHD）。在82%的非扩张胆管病例中可见肝外周三分之一的IHD，在91%的病例中可见四个肝段内的IHD。肝外胆管（EHD），无论扩张与否，在90%的病例中可显示。71%的病例在EHD中发现充盈缺损，100%的病例在胆囊中发现充盈缺损。在大多数病例中，所有梗阻均被识别，其部位和特征均被准确显示。IHD扩张的存在被准确显示，EHD和主胰管管径的测量与直接胆管造影密切相关。
非屏气MR胆管造影是一种可靠的胆道系统成像方法。
