摘　　要：目的:探讨各种影像学检查方法对肾肿瘤的诊断价值,为临床医师选择和设计合理的检查程序提供参考。方法:以病理学诊断为依据,用比较影像学方法,对各种影像学检查的定位、定性诊断正确率进行对比分析。结果:178例肾肿瘤中,恶性肿瘤161例,良性肿瘤17例,IVU、BUS、CDFI、CT、MRI的术前定位诊断正确率分别为37.9%、94.8%、92.3%、96.9%、88.4%;定性诊断正确率分别为27.3%、63.2%(其中囊、实性定性97.1%)、73.1%、77.9%、66.7%,综合影像组则高达100%和87.1%。结论:IVU定位、定性诊断正确率低;BUS对囊、实性的识别力高,可作为初选方法;CT、CDFI、MRI、选择性肾动脉造影对肾肿瘤的定位诊断正确率高,定性诊断正确率相近。综合影像学检查可发挥互补作用,明显提高诊断的正确率。Objective：To provide clinicians with diagnostic strategy and technique selection for renal tumors through evaluating various imaging studies. Method： The accuracy of localizing and qualitative diagnosis was analyzed by comparing various imaging examinations with pathological findings after surgery . Result： Of 178 cases with renal tumors,161 were malignant and 17 were benign. The pre -operation lesionlocalizing accuracy with IVU, BUS, CDFI , CT and MRI was 37.9% ,94.8% ,92.3% ,96.9% and 88.4%, respectively. The qualitative accuracy with the same modalities as above was 27.3% , 63.2%, （ differentiating cystic tumors from solid tumors 97.1% ） ,73.1%, 77.9% and 66.7% respectively. For the group ,in which the diagnosis was made by combining different imaging examinations, the accuracy of localizing and qualitative diagnosis was 100% and 87% ,respectively. Conclusion ：IVU carries lower accuracy in both localizing and qualitative diagnosis , while BUS is powerful in differentiating cystic with solid can be used as a screening method. CT , CDFI and MRI are very accurate in localizing diagnosis , combination of various exarninations can give play to the advantage of different modalities and thus , greatly increase the diagnostic accuracy for renal tumors.
