【摘要】 目的 评价影像学检查在肾细胞癌合并下腔静脉癌栓诊断中的价值。 方法 对18例术前诊断肾细胞癌下腔静脉癌栓病人的影像学检查结果与手术病理结果进行对照分析。 结果 B超诊断肾细胞癌下腔静脉癌栓的准确度为46.2%、敏感度44.4%、特异度50.0%；CT分别为72.2%、71.4%、75.0%；彩超为72.7%、75.0%、66.6%；联合两项以上影像检查则为83.3%、85.7%、75.0%。 结论 CT与彩超对肾细胞癌下腔静脉癌栓的诊断准确度、敏感度、特异度相近，明显优于B超，两项或三项联合检查可明显提高本病诊断准确度、敏感度和特异度，并可替代创伤性大、不良反应多的下腔静脉造影。

    【Abstract】 Objective To evaluate the value of B-modeultrasound (BUS),CT and color ultrasound in the diagnosis of renal cell carcinoma withcancer embolus in the inferior vena cava (IVC). Methods Eighteencases,diagnosed as renal cell carcinoma with cancer embolus in the IVC by BUS,CT and colorultrasound preoperatively,were reviewed.Imaging findings and post-operative pathologicalreports were compared and analyzed. Results The accuracy,sensitivityand specificity of BUS are 46.2% ,44.4% and 50.0% respectively and those of CT 72.2%,71.4%and 75.0%.For color ultrasound these are 72.7%,75.0% and 66.6%.When the imaging procedureswere used combinedly these are 83.3%,85.7% and 75.0%. Conclusions Thereis little difference between CT and color ultrasound in the diagnosticaccuracy,sensitivity and specificity,and both have a great advantage over BUS.Thecombination of two or three of the imaging procedures will greatly enhance theaccuracy,sensitivity and specificity,and can be used instead of venacavography which isinvasive and has some adverse reactions.
