摘要
目的探讨磁共振(MRI)及磁共振胰胆管成像(MRCP)在诊断胆道结石的临床价值。方法对50例经临床和手术证实为胆道结石病人的MRI及MRCP检查资料与B超、CT等检查资料进行对比分析。结果所有病例MRI及MRCP检查全部发现结石;50例均行B超检查,阳性30例;35例行CT检查,25例发现结石;15例行ERCP检查,2例插管不成功,8例成功插管并取石,2例未发现结石,2例出现术后并发症(急性胰腺炎)。结论MRI及MRCP是无创无痛苦检查方法,在胆道结石的诊断中有非常重要的作用,有助于提高诊断准确率。
Objective To evaluate the value of MR and MRCP in the diagnosis of biliary calculi. Methods 50 patients suffering from biliary calculi were examined by MRI and MRCP. MRCP were performed with single shot FSE T2 weighted sequence （SSFSE） and FSE T2 weighted sequence, then the source images were reconstructed through postprocess. The findings of 50 cases verified by operation were compared with those of CT and US. Results All patients were examined by MRI, MRCP, and US, in which calculus was found by MRI and MRCP in all cases, by US in 30 cases. Among the 35 cases undergoing CT examination, 25 cases were found having calculus. 15 cases were examined by ERCP, in which 2 cases failed to cannulate, 8 cases succeeded in cannulation and calculus extraction, 2 cases failed to find calculus, and 2 cases had postoperative complications （acute pancreatitis）. Conclusion MRI and MRCP are noninvasive and pain-free methods in the diagnosis of biliary calculi, which will greatly raise the accurate rate of diagnosis.
