126例梗阻性黄疸患者的磁共振胰胆管成像随访分析

目的：探讨磁共振胰胆管成像（M RC P ）在梗阻性黄疸中的应用价值。方法收集126例临床诊断为梗阻性黄疸的患者，行腹部M RI平扫及M RCP检查，记录诊断结果，持续随访观察，将M RCP诊断结果与随访得到的病理或逆行胰胆管造影（ERCP）结果进行对照分析。结果 MRCP诊断结果与随访结果对比，定位诊断符合率100％。定性诊断 MRCP与随访结果无统计学差异。针对不同原因的梗阻，MRCP具有较高的灵敏度、特异度、阳性预测值及阴性预测值。结论 MRCP在梗阻性黄疸定位及定性诊断方面具有较高的准确性，对不同梗阻原因的判断亦具有较高的诊断价值。

Follow-up analysis of MRCP in 116 patients with obstructive jaundice

Objective To evaluate the application value of magnetic resonance cholangiopancreatography (MRCP) in the pa‐tients suffering from obstructive jaundice .Methods 126 patients diagnosed as obstructive jaundice underwent the abdominal MRCP examination and MRI scanning .The diagnostic results were recorded and the follow‐up observation was persisted .The MRCP diag‐nosis results were compared with the pathological or ERCP results obtained by follow up .Results Comparing the MRCP diagnostic results with the follow up results ,the coincidence rate of location diagnosis was 100% .The MRCP and follow up results in the qual‐itative diagnosis had no statistically significant difference .M RCP had the higher sensitivity ,specificity ,positive value and negative value in the judgement of different causes of obstruction .Conclusion M RCP has the higher accuracy for the qualitative and location diagnosis of obstructive juandice and also has the higher diagnostic value for judging the different obstructive causes .
