Abstract：Objective:To evaluate the value of intravoxel incoherent motion(IVIM)in the differential diagnosis of renal minimal-fat angiomyolipoma(MFAML)and homogeneous renal clear cell carcinoma(CCRCC).Methods:The imaging data of 36 patients confirmed by postoperative pathology were retrospectively analyzed,including homogeneous renal clear cell carcinoma(n=24)and renal minimal-fat angiomyolipoma(n=12).All patients underwent convention-al MRI and IVIM scans before surgery.The IVIM images were analyzed by professional software to obtain the relevant parameter values,and the independent sample t test and ROC curve were used to evaluate the ability to identify the two groups of tumors.Results:There were significant differences in IVIM parameters perfusion fraction(F)and simple dif-fusion coefficient(D)between homogeneous renal clear cell carcinoma and renal lipid-poor angiomyolipoma.Conclu-sion:The parameters D and f of IVIM technology are helpful to distinguish MFAML from homogeneous CCRCC in clinical practice,which provides a new and effective method for the differential diagnosis of these two tumors.
