摘要
目的探讨CT增强扫描联合胆道重建技术在胆总管癌诊断中的价值,提高CT对胆总管术前评估的准确性。方法回顾性分析30例经病理证实为胆总管癌的CT增强图像,并对胆总管进行MPR和CPR,总结胆总管癌的CT表现特点并用统计学方法分析两种重建技术对胆总管癌术前评估的准确性。结果 CPR对胆总管癌的诊断符合率和分型符合率均高于MPR,且差异具有统计学意义(P分别为0.010和0.021),两种重建方式对定位的符合率差异不明显(P=0.317)。胆总管癌的CT主要表现为胆总管管壁的增厚或形成软组织肿块,胆总管、肝内胆管及胆囊明显扩张,增强后胆总管管壁或软组织肿块呈中度以上强化。结论 CT增强扫描可以作为胆总管癌术前的常规检查,胆道重建技术明显提高了胆总管癌术前评估的准确性。
Objective To explore the value of contrast-enhanced CT with bile duct reconstruction in diagnosing cholan- giocarcinoma, and improve the evaluation accuracy of CT before surgery. Methods The contrast-enhanced CT images of 30 cases proven cholangiocarcinoma by pathology, and the common bile ducts were reconstructed by multi-planar reforma- tion （MPR） and curved multi-plain reconstruction （CPR）. The CT findings of Cholangiocarcinoma were concluded and the evaluation accuracy of MPR and CPR were analyzed by statistical methods. Results The compliance rates of CPR in the diagnosis and typing of cholangiocarcinoma were both higher than MPR, and the differences were significant （p-value was 0. 010 and 0. 021 respectively）, but there was no difference between the CPR and MPR in the location of cholangiocarcino- ma. The thickening wall and the soft tissue masses enhanced moderately or severely with expansion of common bile duct, intrahepatic bile duct and gallbladder were the main CT finding in diagnosing Cholangiocarcinoma. Conclusion Contrast- enhanced CT can be used as a normal examination method in diagnosing the cholangiocarcinoma, and the bile duct recon- struction can improve the evaluation accuracy before the surgery.
