Evaluation of 3.0T MR Diffusion-Weighted Imaging in Renal Malignant Tumor

¹Cancer Institute and Hospital, Chinese Academy of Medical Sciences, Beijing, China

DWI in 3.0T MRI made it possible to diagnose tumor, which can be quantitatively measured by ADC value. Comparison of ADC value was performed in 66 renal malignant tumors. Significant differences were found between normal renal cortex and renal carcinoma, non-clear cell carcinoma and clear cell carcinoma respectively. Among groups of clear cell carcinoma, there were statistic differences between grade and , grade and respectively. Therefore 3.0T MR-DWI can be used in diagnosis of renal malignant tumor, while ADC value was helpful in differentiating its pathological type and grade.
