ABSTRACT
Objective To study the value of spiral CT in diagnosing renal cell carcinoma(RCC) and to evaluate the correlation of CT findings with histopathologie features in RCC. Methods 279 cases with RCC proven by surgery and pathology underwent plain and contrast-enhanced CT examinations. The clinic characteristics and CT findings were analyzed statistically and compared with surgical results. Results 90.32% lesions showed medium or obvious enhancement on contrast-enhanced CT,with the exception of granule cells for enhanced uniform, the other cell type of RCC showed heterogeneous enhancement. 32.26% of tumors was of more or less short-burres (χ~2 = 38.2,P<0.01) ,and the there was significant relationship between pathological signs of short burr and the renal capsule involved by tumors. CT qualitative diagnostic rate was 91.40%. CT staging and pathologic staging were of the correla-tive coefficient of 0. 84, while there was not obviously correlation between CT classification of RCC and cancer cell types(P>0.05). Conclusion Spiral CT can better show characteristics of RCC, that can improve the diagnostic accuracy and staging aility for RCC.
