目的探讨MR三维容积内插体部检查(volume interpolated body examination,VIBE)增强联合冠状位T2WI诊断肝外远端胆管癌的价值。方法 17例经手术病理证实的肝外远端胆管癌行MR冠状位T2WI、VIBE增强扫描,观察病灶的MR表现,测量病灶长度。结果 17例肝外远端胆管癌在冠状位T2WI上表现为肝外远端胆管梗阻,10例于胆管梗阻处见软组织肿块、3例见胆管壁增厚,同周围组织相比呈低信号。VIBE动态增强扫描17例病灶均呈进行性强化,10例肿块者中2例均匀性强化,8例肿块边缘强化更明显;7例胆管壁增厚、强化,在轴位VIBE图像上呈“环”形强化,在冠状位VIBE图像上,5例呈平行的“线条”状强化,2例呈“V”形强化。病灶平均长度为18.7 mm。结论 VIBE增强联合冠状位T2WI能较好地显示肝外远端胆管癌。
Objective To investigate the value of MR three dimensional volume interpolated body examination (VIBE) combined with coronal T2WI in the diagnosis of extrahepatic extrahepatic cholangiocarcinoma. Methods Seventeen patients with pathologically confirmed extrahepatic extrahepatic cholangiocarcinoma underwent MR coronary T2WI and VIBE enhanced scanning. MR imaging was performed to observe the lesion length. Results 17 cases of extrahepatic extrahepatic cholangiocarcinoma showed distal extrahepatic bile duct obstruction in the coronal T2WI, 10 cases of soft tissue mass in the bile duct obstruction, 3 cases of thickening of the bile duct wall, and low signal compared with the surrounding tissues. VIBE dynamic enhancement scan in 17 cases were progressive enhancement, 10 cases of mass in 2 cases of enhanced homogeneity, 8 cases of enhanced edge more obvious enhancement; 7 cases of bile duct wall thickening, strengthening, axial VIBE images were “ Ring ”shape enhancement. In the coronal VIBE images, 5 cases were parallel with“ line ”shape enhancement and 2 cases were“ V ”shape enhancement. The average length of the lesions was 18.7 mm. Conclusion VIBE enhanced coronal T2WI can better show the extrahepatic bile duct cancer.
