摘　　要：目的:评价各种影像学检查方法对肾癌的诊断价值。方法:回顾性分析经手术病理证实的肾癌119例,将各种影像诊断结果进行比较分析。结果:静脉肾盂造影能间接显示肿瘤占位征象,诊断价值有限;超声具有一定的诊断价值,且操作简单、价格低廉;CT和MRI能直接显示肿瘤内部结构及其周围情况,诊断价值最高;DSA可直接显示肿瘤血管,对区别良、恶性病变有很高价值。结论:超声应作为首选检查;CT和MRI两者之一应列为肾癌的常规检查项目;DSA作为创伤性检查一般很少单独用于诊断,只在栓塞治疗前使用。Purpose：To evaluate the value of different imaging examination methods in the diagnosis of renal cell carcinoma.Methods：One hundred and nineteen patients with pathologically proved renal cell carcinoma were retrospectively analyzed. All the imaging diagnostic results were compared.Results：IVP could indirectly displayed occupying sign of the tumor and its diagnostic value was limited. US had definite diagnostic value,furthermore its operation was simple and expenditure was low. CT and MRI could directly display internal configuration and surrounding status of tumor,which possessed the highest diagnostic value. DSA might directly reveal tumorous vessels,which had high value in differentiation of benign and malignant disease.Conclusions：US should take as the preferred examination of renal cell carcinoma.Either CT or MRI should be ranked as one of conventional examinations.DSA is seldom used alone just for the aim of diagnosis,which was a invaded method.It was only used before embolization therapy.
