Abstract: Objective To investigate the value of quantitative analysis in the diagnosis of renal lesions with contrast-enhanced ultrasound.Methods Sixty cases with renal lesions confirmed by surgery and pathology underwent contrast-enhanced ultrasound preoperatively and quantitative analysis retrospectively.The Sonoliver software was applied in the analysis of CEUS imaging and in the recoustruction of quantitative parameter,s.Five parameters were calculated,including the maximum intensity (IMAX),rise time (RT),time to peak (TTP),mean transit time (mTT) and area under the curve (AUC).Results There were statistically differences in parameters RT,mTT and AUC ( P ＜ 0.05) and significant differences in parameter IMAX ( P ＜0.01).In malignant tumors,the RT and mTT were less than that of the benign while IMAX and AUC were more than that of the benign.Conclusions Contrast-enhanced ultrasound using a quantitative parametric analysis offers more information and is a promising tool in the diagnosis and differentiation of renal masses.
