目的探讨MRCP中胆管内絮状沉积物的表现及意义。方法分析326例胆管扩张的病人MRCP,所见与轴位T2WI、T1WI、冠位T2W及ERCP检查和(或)手术相对照。结果 MRCP图像中胆管内絮状沉积物见于中-重度扩张胆管内,表现为条状、柱状稍低信号充盈缺损;轴位T2WI显示圆形稍低信号或呈分层状。ERCP检查和T管引流手术证实其存在。结论 MRCP结合MRI对胆管絮状物沉积有很高诊断价值。
Objective To investigate the expression and significance of flocculent sediments in MRCP. Methods 326 cases of bile duct dilatation in patients with MRCP, seen with axial T2WI, T1WI, coronary T2W and ERCP examination and (or) surgery. Results In the MRCP images, flocculent deposits in the bile ducts were found in the medium-severe dilatation bile duct, which showed a strip shape with a slightly lower column filling defect. The T2WI axis showed slightly lower circular or stratified. ERCP examination and T-tube drainage confirmed its presence. Conclusion MRCP combined with MRI has a high diagnostic value of biliary floc deposition.
