磁共振胰胆管成像结合薄层T2WI扩散加权成像对胰胆道梗阻性病变的诊断价值评估

Diagnosisand assessment of MRCP with thin-layer T2WI DWI in biliary obstractive disease

目的评价磁共振成像(MR)水成像技术结合薄层T2WI、扩散加权成像(DWI)在胰胆道梗阻性病变中的临床诊断价值。方法采用重T2加权MR水成像技术及薄层T2WI、DWI对36例患者行磁共振胰胆管成像(MRCP)检查,图像经三维最大信号强度投影及三维表面遮盖显示技术后处理。结果水成像及薄层T2WI、DWI定位诊断率达100%,定性诊断率达88.6%,此技术可清晰显示胰胆管的形态,显示各种胰胆道疾病的异常改变,诊断正确性高。结论对胰胆道梗阻性病变的患者进行MRCP结合薄层T2WI、DWI扫描,诊断胰胆管梗阻的原因更为准确,可以作为常规检查序列推广应用。

Objective Evaluation of MR hydrography combined with thin layer of T2WI, DWI the diagnostic value of pancreatic biliary obstructive lesions. Methods Heavily T2-weighted MR hydrography techniques and thin layer T2WI, DWI, 36 patients underwent MRCP, image post-processing three-dimensional maximum intensity projec-tion and three-dimensional surface shaded display technology. Results Water imaging and thin T2WI and DWI, posi-tioning diagnosis rate of 100%, qualitative diagnosis rate of 88.6%. This technique can clearly show the morphology of the pancreatic duct, show the abnormal changes of the various pancreatic biliary tract disease, high diagnostic accura-cy. Conclusion Patients with pancreatic biliary obstructive diseases MRCP combined with a thin layer of T 2WI, DWI scan, a more accurate diagnosis of pancreatic biliary obstruction sequence to promote the application as a routine ex-amination.
