Abstract:
Objective To investigate the differential value of contrast-enhanced ultrasonography (CEUS) and time-intensity curves(TIC) in diagnosing testicular and epididymal mass lesions.Methods CEUS via intravenous bolus injection of SonoVue and TIC were performed for quantitative analysis of testicular and epididymal mass lesions.Forty-one patients with 42 testicular and epididymal mass lesions and 26 normal testicles were examined with CUES,the perfusion progress were recorded dynamically,which findings were compared with surgery.Results Twenty-three (54.76％) malignant masses displayed enhanced pattern as evenly enhanced,fast-in and fast-out (8.7％),evenly enhanced,fast-in and slow-out (65.2 ％ ),unevenly enhanced,fast-in and slow-out (26.1％ ).Ninteen (45.24 ％ ) benign masses revealed enhanced pattern as unevenly enhanced,fast-in and slow-out ( 10.5 ％),evenly enhanced,slow-in and slowout ( 10.5 ％ ),unevenly enhanced,slow-in and slow-out ( 36.9 ％ ),without enhancement ( 42.1％ ).There was statistical difference of peak intensity,time to peak and areas among malignant group,benign group and normal group ( P ＜ 0.05).Conclusions CEUS combined with TIC could provide differential diagnostic value for testicular and epididymal mass lesions.
