摘　　要：目的探讨MRCP联合容积内插体部检查(VIBE)多期动态增强扫描诊断梗阻性黄疸病因的价值。方法回顾性分析经术后病理证实的125例梗阻性黄疸患者的MRCP和VIBE多期动态增强扫描资料,计算和比较MRCP、VIBE多期动态增强扫描及二者联合诊断梗阻性黄疸病因的准确率。结果 MRCP、VIBE多期动态增强扫描及二者联合诊断梗阻性黄疸病因的总准确率分别为76.80%(96/125)、80.80%(101/125)和84.80%(106/125),三者比较差异无统计学意义(P=0.275);良性梗阻74例,三者诊断其病因总准确率分别为91.89%(68/74)、86.49%(64/74)和90.54%(67/74),差异无统计学意义(P=0.532);恶性梗阻51例,三者诊断其病因总准确率分别为54.90%(28/51)、72.55%(37/51)和76.47%(39/51),其中VIBE多期动态增强扫描联合MRCP准确率明显高于单纯MRCP(P=0.022)。结论 MRCP联合VIBE多期动态增强扫描诊断梗阻性黄疸、尤其是恶性梗阻性黄疸病因准确率高。Objective To investigate the value of magnetic resonance cholangiopancreatography （MRCP） combined with volume interpolated body examination （VIBE） dynamic contrast enhancement scanning in etiological diagnosis of obstructive jaundice. Methods MRCP and VIBE dynamic contrast enhancement scanning data of 125 patients with obstructive jaundice confirmed by postoperative pathology were retrospectively reviewed. The accuracy of MRCP, VIBE dynamic contrast en- hancement scanning and combination of them in etiological diagnosis of obstructive jaundice were calculated and compared. Results The summary accuracy of MRCP, VIBE dynamic contrast enhancement scanning and combination of them in etio- logical diagnosis of obstructive jaundice was 76. 80% （96/125）, 80.80% （101/125） and 84.80% （106/125）, respectively （P=0. 275）. The summary accuracy of the three methods in etiological diagnosis of benign obstruction （n= 74） was 91.89% （68/74）, 86.49% （64/74） and 90.54% （67/74）, respectively （P=0. 532）. The summary accuracy of the three methods in etiological diagnosis of malignant obstruction （n= 51） was 54.90% （28/51）, 72. 55% （37/51） and 76.47% （39/51）, respectively, and statistical difference was found between MRCP combined with VIBE dynamic contrast enhance- ment scanning and single MRCP （P= 0. 022）. Conclusion MRCP combined with VIBE dynamic contrast enhancement scanning has high diagnostic accuracy in etiological diagnosis of obstructive jaundice, especial malignant obstructive jaun- dice.
