• small renal tumors
• dynamic MR
• multiphasic CT

Purpose: To implement and correlate imaging dataset with the anatomical/histopathologic ones, in order to obtain a better characterization of small renal lesions, to determine valid criteria into differential diagnosis between small renal tumors and to evaluate the value of MR diffusion sequences into the study of small renal lesions. %26lt;br%26gt;Materials and methods: : 41 patients in total (11 females and 30 males, average age 68), with a total of 63 renal lesions examinated, subjected to triphasic magnetic resonance imaging and triphasic computed tomography. %26lt;br%26gt;Results:In about 17 cases of oncocytomas, 17 were homogeneous and deprived of the pseudo capsule; 3 lesions appeared inhomogeneous in relation to the presence of a central scar (demonstrated in tardive excretory phase), and excluded from the study. Of 17 carcinomas, 16 (94%) are inhomogeneous, of these 3 with pseudo capsule; 1 (6%) are homogeneous and without capsule. %26lt;br%26gt;Conclusions: The enhancement qualitative-quantitative determination of these lesions, which had been considered a potentially valid criterion, fails to give us a definite differential diagnosis of small lesions.
