报告７例肝门胆管癌经ＰＴＣ螺旋ＣＴ胆道成像，其图象比ＰＴＣ清晰，立体感强，且可多方位观察。在判定病变部位，反映肝内胆树受累范围和程度上，优于ＰＴＣ、电脑彩超、Ｂ超；在判定血管受犯、肝内外转移和远处淋巴转移上，与电脑彩超一致，优于Ｂ超。结果提示经ＰＴＣ螺旋ＣＴ胆道成像在肝门胆管癌定位诊断、评估肿瘤切除可能性及术式选择上具有一定价值。
Seven cases of hepatic hilar cholangiocarcinoma were treated with PTC spiral CT biliary imaging. The images were clearer than PTC, and the stereoscopic effect was strong and could be observed in multiple directions. It is superior to PTC, computer color Doppler ultrasonography and B-mode ultrasound in determining the lesion site and reflecting the extent and extent of involvement of intrahepatic bile tree; it is consistent with computer color ultrasound in judging vascular invasion, intrahepatic metastasis and distant lymph node metastasis, and is superior to B ultra. The results suggest that the use of PTC spiral CT biliary imaging in the diagnosis of hilar cholangiocarcinoma, evaluation of the possibility of tumor resection and surgical selection has a certain value.
