摘　　要：目的探讨超声造影及时间-强度曲线对睾丸附睾肿块的诊断价值。方法采用超声造影剂SonoVue和时间-强度曲线定量分析26个正常睾丸（对照组）和42个睾丸和附睾肿块（病例组），并与手术病理对照。结果42个睾丸附睾肿块中23个（54．76％）为恶性，19个（45．24％）为良性。恶性肿块的主要增强方式为均匀增强、快进快出（8．7％），均匀增强、快进慢出（65．2％），不均匀增强、快进慢出（6．1％）。良性肿块的主要增强方式为：不均匀增强、快进慢出（10．5％），均匀增强、慢进慢出（10．5％），不均匀增强、慢进慢出（36．9％），无增强（42．1％）。时间-强度曲线峰值强度、达峰时间及曲线下面积在恶性组、良性组及正常组间差异均有统计学意义（P〈0．05）。结论超声造影和时间-强度曲线对睾丸附睾良恶性肿块有明显鉴别诊断价值。Objective To investigate the differential value of contrast-enhanced ultrasonography （CEUS） and time intensity curves（TIC） in diagnosing testieular and epididymal mass lesions. Methods CEUS via intravenous bolus injection of SonoVue and TIC were performed for quantitative analysis of testieular 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 testieular and epididymal mass lesions.
