摘　　要：目的探讨MR3D—VIBE序列与MR常规序列（包括MRCP）对诊断胆管癌及对手术可切除性评估的价值。方法对20例胆道恶性梗阻的病例，术前先行上腹部MR常规序列（包括MRCP），后采用MR3D—VIBE序列进行平扫并动态增强扫描。分析肿瘤的MR征象，并对肿瘤是否可手术切除进行评估。对比分析MR常规序列与3D—VIBE序列对瘤体检出的敏感率和瘤体侵犯邻近器官的阳性征象显示差异。结果20例胆管癌病例，MR常规序列对瘤体显示的敏感率为85％，3D—VIBE序列对瘤体显示的敏感率为95％。MR常规序列与3D—VIBE序列对14例手术患者瘤体侵犯邻近器官的阳性征象数量显示差异有统计学意义（P〈0．05）。结论3D—VIBE序列在胆管癌瘤体检出、早期诊断、侵犯范围和手术切除性评估方面优于常规MRI序列。Objective To study the value of MR three-dimensional volumetric interpolated breath-hold examination（3D- VIBE）and conventional MR imaging （including MRCP） in diagnosing cholangiocarcinoma early and evaluating the respectability of cholangiocarcinoma. Methods 20 patients with malignant obstruction of bile duct were scaned by conventional MR imaging（including MRCP） and dynamic-enhanced 3D-VIBE triple-phase acquisitions. MR imaging features of the tumors were analysed and the respectability of cholangiocarcinoma was also evaluated. The differences between conventional MR imaging and 3D-VIBE in displaying the tumors and the infiltration extent of the tumors were compared. Results The sensitivity ratio in showing the tumors were 85 and 95 % with conventional MR imaging and 3D-VIBE, respectively, and there was statistically significant difference between two sequences in displaying infiltration of adjacent organs by the tumors（P〈0.05）. Conclusion 3D-VIBE is superior to conventional MR imaging in the early diagnosis, preoperative assessment of the infiltration extent and the tumor respectability of cholangiocarcinoma.
