Abstract：Objective: To investigate the differential diagnostic value of diffusion-weighted magnetic resonance imaging in renal cell carcinoma and renal angiomyolipoma with minimal fat. Methods: One hundred and thirty-seven patients with pathological diagnosis RAML were collected from 2012.1 to 2014.12, 122 cases with definite mature adipose tissue were dismissed, and then 15 cases with integrated data of MRI were collected, and 31 cases of renal cell carcinoma with completely radiological materials were collected as well. These signal characteristics of diffusion-weighted magnetic resonance imaging were analyzed, the value of ADC in lesion was measured, and their statistical differences were analyzed. Results: In 15 cases of RAML, 6 cases were male, 9 cases female, and the average age 47±6.0, the average value of ADC (1.62±0.18) ×10-3 mm2/s; and in 31 cases of RCC, 14 cases were male, 17 cases female, and the average age 63±7.5; 19 cases were clear-cell renal carcinoma, 7 cases were papillary renal carcinomas, and 5 cases chromophobe renal cell carcinoma, the average value of ADC was (1.460±0.283) ×10-3 mm2/s; the value of ADC was significant statistical difference (P<0.05) in renal cell carcinoma and renal angiomyolipoma with minimal fat. The sensitivity and specificity of differential diagnostic was 86.7% and 77.4%, respectively, while the value of ADC selected was 1.57×10-3 mm2/s. Conclusion: The value of the ADC of diffusion-weighted magnetic resonance imaging in renal cell carcinoma and renal angiomyolipoma with minimal fat is significant difference; there are definitive diagnostic values in renal cell carcinoma and renal angiomyolipoma with minimal fat.
