摘　　要：目的 :应用彩色多普勒血流显像 (CDFI)观察胰腺癌肿的声像图特征 ,探讨胰腺癌周邻血管累及与胰腺癌患者手术切除可行性之间的关系。方法 :对临床上疑及胰腺癌的 64例患者进行CDFI检查 ,其中 43例同时进行了CT检查 ,所有病例均经手术病理证实。结果 :①与 43例同时进行CT检查的患者相比 ,CDFI的检出率为 81.2 % ,CT的检出率为 90 .7% ,两种方法经比较差异无显著性意义 (P >0 .0 5 ) ;②CDFI显示肿瘤未累及周邻血管者 3 9例 ( 60 .9% ) ,累及周邻血管呈推挤、移位受压或血管包绕者 2 5例 ( 3 9.1% )。与手术结果相比 ,CDFI的诊断灵敏度为 69.4% ,假阴性率 17.2 %。结论 :CDFI不仅可作为非损伤性的检测手段替代CT检查 ,而且通过显示胰腺肿瘤与周围邻近血管的关系对指导手术治疗提供了重要的依据。Objective:To study the characteristic features of pancreatic carcinoma on CDFI,and explore the relationship between the vascular involvement and operability of the tumor.Methods:64 patients underwent CDFI examination of pancreas, 43 of them also received CT scan. All patients were confirmed by operation.Results:①The depicting rate of CDFI for the tumor was 81.2%, while that of CT was 90.7%. There was no significant difference between both methods( P >0.05). ②No involvement of the vessels was found in 39 patients (69.9%),while vascular involvement was found in 25 patients (39.1%).As compared with the operative findings,the diagnosis sensibitity was 69.4%,and the false negative rate was 17.2%.Conclusion:CDFI is not only a valuable method for detecting pancreatic carcinoma, but it is also an non invasive method for evaluation of vascular involvement and can provide important information for planning of surgical treatment.
