目的讨论各种影像检查对肾恶性肿瘤的诊断价值，并就某些征象进行分析，以提高诊断正确率。方法对经影像检查并得到病理证实的肾恶性肿瘤４３例进行分析，比较各种检查方法对肾恶性肿瘤的检出率和定性率。结果肾恶性肿瘤的检出率以ＣＴ和ＭＲＩ为最高，Ｂ超次之，静脉肾盂造影（ＩＶＰ）最低。而定性率以ＭＲＩ最高，ＩＶＰ最低。结论ＭＲＩ及ＣＴ检查对肾恶性肿瘤诊断的价值最大，Ｂ超可作为普查手段。肾癌在ＣＴ检查中发现肿瘤中心钙化及ＭＲＩ检查中出现假包膜的征象均为较可靠的诊断依据之一
Objective To discuss the diagnostic value of various imaging examinations for renal malignant tumors and to analyze some signs to improve the diagnostic accuracy. Methods 43 cases of renal malignant tumors confirmed by pathology and image examination were analyzed. The detection rate and the qualitative rate of renal malignant tumors by various examination methods were compared. Results The detection rate of renal malignant tumors was the highest in CT and MRI, the lowest in B ultrasound and IVP. The qualitative rate of the highest MRI, IVP the lowest. Conclusion MRI and CT examination have the greatest value in the diagnosis of renal malignant tumors, B-ultrasound can be used as a census method. Renal cancer found in the CT examination of tumor center calcification and MRI examination of the appearance of false envelopes are more reliable diagnostic basis
