Abstract: Objective To explore the application value of CEUS in diagnosis of renal occupying lesions.Methods Totally 67 patients with renal occupying lesions underwent conventional ultrasound and CEUS before surgical operation.CEUS enhancement characteristics were observed and compared between 40 patients with clear cell renal cell carcinoma (CCRCC)and 14 patients with angiomyolipoma (AML).Meanwhile the time-intensity curves were analyzed,including peak intensity (IMAX),rise time (RT),time-to-peak time (TTP) and mean transit time (mTT).Results There were significant differences in enhancement patterns,degrees,homogeneity of enhancement and pseudocapsule sign between CCRCC and AML (all P＜0.01).Compared with AML,IMAX of CCRCC was higher,RT and mTT were both earlier (P＜0.05).The sensitivity,specificity and accuracy of CEUS in diagnosis of malignant renal occupying lesions was 91.49 ％ (43/47),75.00 ％(15/20) and 86.57％ (58/67),respectively.Conclusion CEUS combined with quantitative analysis software is helpful to diagnosis and identification of CCRCC and AML.
