摘要

Purpose To compare various CT perfusion features of fat poor angiomyolipoma (AML) with those of size-matched renal cell carcinoma (RCC). Methods One hundred and seventy-four patients [16 with fat poor AML (mean diameter, 3.1?cm; range, 1.5–5.5?cm) and 158 with RCC (mean diameter, 3.2?cm; range, 2.4–5.4?cm)] who had undergone 320-slice dynamic volume CT perfusion were evaluated. Equivalent blood volume ( BV ~(Equiv)), permeability surface-area product (PS), and blood flow (BF) of tumor were measured and analyzed. Fat poor AML was compared with each subtype of RCC (132 clear cell, 9 papillary, and 17 chromophobe). Receiver operating characteristic (ROC) curve analysis was performed for the comparison of fat poor AML and RCC. ROC curve analysis was not performed for the papillary RCC subtype because of the small number of masses of this subtype. Results BV ~(Equiv)and BF were significantly lower in fat poor AML than in clear cell RCC ( P ?
