摘　　要：目的：评价CT、彩超诊断肾癌合并下腔静脉癌栓的应用价值。方法：对18例术前经CT、彩超诊断为肾癌下腔静脉癌检病人的影像检查结果与手术病理诊断进行对照分析。结果：CT诊断准确度72．2％、敏感度714％、特异度75％、阳性预测值90．9％；彩超则分别为72.7％、75％、66.7％、857％；联合检查组则为90．9％、100％、66．7％及88．9％，联合检查诊断准确度明显优于CT或彩超单项检查。结论：CT或彩超诊断肾癌下胜静脉癌栓有一定价值，联合检查可明显提高诊断能力，并可替代创伤性大的下腔静脉造影。Purpose: To evaluate the value of CT and color ultrasound in the diagnosis of renal cell carcinoma with cancer em-bolus in the inferior vena cava(IVC). Materials and Methods: Eighteen cases, diagnosed as renal cell carcinoma with cancerembolus in the IVC by CT and color ultrasound preoperatively, were selected. Imaging examination results and post - opera-tive pathological reports were compared. Results: The accuracy, sensitivity, specificity and expected positive value of CT were72. 2 %, 71. 4 %, 75 % and 90. 9 % respectively. And they were 72. 7 %, 75 %, 66. 7 % and 85. 7 % respectively for the col-or ultrasound. 90. 3 %, 100 %, 66. 7 % and 88. 9 % for the combined group, showed a great advantage of accuracy over foreach one test. Conclusion: CT or color ultrasound is worthy in diagnosing the renal cell carcinoma with cancer embolus in theIVC. The combination of the two will greatly enhance the diagnostic capibility and can replace the invasive venacavography.
