To determine the reliability and efficacy of magnetic resonance (MR) cholangiography in demonstrating the site and extent of stricture.
In 40 patients with obstructive jaundice, three-dimensional MR cholangiography was performed with a sequence of mirrored fast imaging with steady-state precession and was compared with conventional cholangiography in 39 cases. The level of obstruction was determined by examining all imaging data available.
Diagnostic MR cholangiograms were acquired in 39 patients; absence of obstruction was confirmed in three, and obstruction was seen in 36. The level of obstruction or absence of obstruction was accurately shown in 36 of 40 patients with MR cholangiography and in 37 of 39 patients with conventional cholangiography. The peripheral biliary tree was shown more completely with MR cholangiography than with endoscopic retrograde cholangiography in all 32 patients undergoing diagnostic studies with both modalities.
Three-dimensional MR cholangiography shows particular promise for the assessment of complex strictures, in which conventional cholangiography carries a higher risk of sepsis, for planning optimal drainage before intervention.
确定磁共振（MR）胆管造影在显示狭窄部位及范围方面的可靠性和有效性。
对40例梗阻性黄疸患者采用稳态进动快速成像序列进行三维MR胆管造影，并与39例患者的传统胆管造影进行比较。通过检查所有可用的影像数据来确定梗阻水平。
39例患者获得了诊断性MR胆管造影图像；3例证实无梗阻，36例可见梗阻。40例患者中，36例通过MR胆管造影准确显示了梗阻水平或无梗阻情况，39例患者中37例通过传统胆管造影准确显示。在接受两种检查方式诊断性研究的所有32例患者中，MR胆管造影比内镜逆行胆管造影更完整地显示了肝外胆管树。
三维MR胆管造影在评估复杂狭窄方面显示出特别的前景，对于在干预前规划最佳引流，传统胆管造影导致脓毒症的风险更高。
