摘要目的研究动态增强CT的廓清效应能否预测肝外胆管细胞癌(EHC)病人的生存期。方法本研究共收集46例手术切除的病人。所有病例均行多层螺旋CT动态增强检查。兴趣区(ROI)选择肿瘤的平扫、静脉期和延迟期并用以下方法计算廓清率:[(静脉期CT值-延迟期CT值)/(静脉期CT值-平扫CT值)]×100%。根据廓清率的中位数,将所有病例
Abstract Objective To investigate whether the clearance effect of dynamic enhanced CT can predict the survival of patients with extrahepatic cholangiocarcinoma (EHC). Methods A total of 46 surgically resected patients were collected in this study. All cases underwent multi-slice spiral CT dynamic enhanced examination. Region of Interest (ROI) Tumors were selected for flat scan, venous phase, and delayed phase and the clearance rate was calculated as follows: [(venous phase CT value - delayed phase CT value) / (venous phase CT value - CT value)] 100 %. According to the median clearance rate, all cases will be
