摘　　要：[背景]探讨MRI弥散加权成像(DWI)技术在肾良恶性肿瘤鉴别诊断中的应用价值.[病例报告]回顾性分析12例经CT检查证实和10例经手术后病理检查证实的肾血管平滑肌脂肪瘤共22例、20例经手术后病理检查证实的肾癌的DWI表现.目测法:22例肾血管平滑肌脂肪瘤中19例的DWI表现为略低或等信号,3例病灶在DWI表现为不均匀高信号,20例肾癌在DWI均表现为不均匀高信号.[讨论]DWI技术对肾脏良恶性肿瘤的鉴别诊断具有应用价值.BACKGROUND To investigate the application value of magnetic resonance imaging （MRI） diffusion weighted imaging （DWI） technique in differential diagnosis of renal malignant and benign tumors. CASE REPORTS It was retrospectively analyzed that 22 cases of renal angiomyolipoma, in which there were 12 cases verified by CT and 10 cases confirmed by operation and pathology, and 20 cases of renal cell carcinoma confirmed by operation and pathology. By using visual method, 19 cases of renal angiomyolipoma in DWI had slightly lower or equal signal, 3 cases had uneven high signal, and 20 cases of renal carcinoma in DWI are uneven h application value in igh signal DWI. DISCUSSION MRI diffusion weighted imaging technique has the the differential diagnosis of benign and malignant renal tumors.
