Abstract Objective: To explore the imaging features between color Doppler flow imaging (CDFI) and contrast-enhanced ultrasonography (CEUS) in clear cell renal cell carcinoma, and evaluate the performance characteristics. Methods: The features of CDFI and CEUS of 34 CCRCC confirmed by operation and pathology were retrospectively analyzed, the characteristics of CDFI and the enhancement and wash out in different phases of CEUS were analyzed. Results: ①The imaging features of CDFI in CCRCC could be classified as two types, 10 cases of the CCRCC were rich in blood and the blood flow were not rich and in 24 cases. ②Enhancement patterns of renal clear cell carcinoma could be performed differently, and they were divided into four models. Twenty-six cases of the CCRCC indicated contrast enhancement patterns of fast in and fast out; six cases indicated that fast in and slow out; one case indicated that slow in and slow out; one case indicated that slow in and fast out. The degree of enhancement was divided into three types. Twenty-five cases of the CCRCC performed as hyper-enhancement; five cases performed as iso-enhancement; four cases performed as hypo-enhancement. The enhancement shape were mainly performed as two types, fourteen cases as rim enhancement and twenty cases as nonhomegeneous enhancement. The performance characteristics of CCRCC in the imaging of CEUS were fast in and fast out, the peak intensity, rim enhancement, nonhomegeneous enhancement. The diagnostic accuracy of CCRCC was 52.94% by CDFI and was 82.35% by CEUS, where significant difference was observed (P<0.05). Conclusion: CEUS shows some characteristic enhancement features, can display tumor vascularity and blood perfusion feature more sensitively than CDFI, and the confidence can be improved by the application of CEUS combined with CDFI.
