【摘要】Objective To investigate the diagnostic value of CT perfusion parameters for tumors of kidney. Methods Forty-two cases of renal cell carcinoma and 15 cases of renal tumors, which had integrated clinical information and pathological data, were enrolled. CT perfusion scanning ran at the maximum slice of tumor after plain scanning in all cases. The post-processing software was used to detect the blood flow( BF ),blood volume( BV ),mean transit time( MTT ) and permeability surface( PS ). Results The mean values of BF, BV,PS in renal cell carcinoma were significantly higher than those in benign tumors of kidney and contralateral kidney( P ＜0. 001 ), however,no statistical difference was found in MTT( P ＞0. 05 ). The mean values of BF,BV,PS in benign tumor of kidney were significantly lower than those of normal contralateral kidney( P ＜0. 001 ) ,but there was no statistical difference in MTT( P ＞ 0. 05 ). Conclusion CT perfusion can reflect the morphological characteristics of tumors of kidney. CT Perfusion may be used to evaluate the benign or malignat tumors of kidney.%目的 探讨多层螺旋CT灌注成像对肾脏良恶性肿瘤的诊断价值.方法 本研究共包括42例肾细胞癌及15例肾脏良性肿瘤,均有完整的临床和病理资料.对所有病例先行常规肾脏CT
