【摘要】Objective To explore the possibility of predicting the histopathological types of small renal cell carcinoma (RCC) by analyzing the different ways of enhancement with multiphasic multidetector computed tomography (MDCT) of small renal cell carcinomas (diameter ≤4 cm).Methods CT images of 93 cases, diagnosed as RCC by pathology, were analyzed retrospectively, including 70 clear cell renal cell carcinoma (CCRCC), 13 papillary renal cell carcinoma (PRCC) and 10 chromophobe renal cell carcinoma (CRCC).All of the cases were examined by multiphasic multidetector CT scanning.Results In plain scans, 46 CCRCCs were homogeneous, 21 CCRCCs were heterogeneous with low-density area and 3 of them had calcification.CCRCCs were enhanced in contrast scan with a presence of \in and wash out\enhancement in general.11 PRCCs were homogeneous and 2 PRCCs had calcification.Slight-homogeneous
