目的探讨64排螺旋CT曲面重建(CPR)技术在胆管癌术前评估中的临床应用价值。方法收集42例胆管癌术前评估患者行64排螺旋CT上腹部增强三期扫描,门静脉期扫描数据进行CPR重建,对胆管癌术前评估诊断与手术结果对比分析,评价CPR对胆管癌术前可切除性评估的准确性。结果 CPR对胆管癌术前胆管癌及受侵润胆管显示率达100%,均能显示受侵润胆管的毗邻关系和肿瘤范围,术前评估胆管癌可切除性准确率达100%。结论 CPR可直观地显示受侵润胆管及胆管癌的毗邻关系,对胆管癌术前可切除性评估有重要价值。
Objective To investigate the clinical value of 64-slice spiral CT surface reconstruction (CPR) in the preoperative evaluation of cholangiocarcinoma. Methods Forty-two patients with preoperative cholangiocarcinoma who underwent preoperative evaluation of 64 cases of spiral CT were enrolled in this study. Three stages of upper abdominal augmentation scan and portal venous scan data were collected for CPR reconstruction. Comparisons were made between preoperative evaluation and surgical findings of cholangiocarcinoma. Accuracy of resectability assessment. Results CPR showed 100% preoperative cholangiocarcinoma and invasive bile duct, both of which showed the adjacent relationship and the tumor range of the affected bile duct. The accuracy of preoperative evaluation of the resectability of bile duct carcinoma was 100%. Conclusion CPR can visually show the adjacent relationship between the invasion of biliary ducts and cholangiocarcinoma, which is of great value in the evaluation of preoperative resectability of cholangiocarcinoma.
