Sequential scrotal scintigraphy was used to study testicular blood flow in 122 patients with clinically diagnosed varicocele. The sensitivity of scrotal scintigraphy was 91.7% on the whole sequential images. The late-phase image was superior in sensitivity to that of the early-phase images. The difference in time between the arrival of radioactivity in the iliac artery and in the pampiniform plexus grew shorter with increasing grade of varicocele. Time-activity curves were classified into four patterns. One type (Type 3), which was more frequently observed in grade II and grade III varicocele than grade I varicocele, showed a decreased arterial perfusion of the left side lesion. It is concluded that scintigraphic analysis using both sequential images and time-activity curves is not only highly representative of the grade of clinically palpable varicocele, but also provides a better understanding of local hemodynamics in the scrotum.
采用连续阴囊闪烁扫描术对122例临床诊断为精索静脉曲张的患者进行睾丸血流研究。在整个连续图像上，阴囊闪烁扫描术的敏感性为91.7%。晚期图像的敏感性优于早期图像。随着精索静脉曲张程度加重，放射性物质到达髂动脉和蔓状静脉丛的时间差缩短。时间-活性曲线分为四种类型。其中一种类型（3型）在II级和III级精索静脉曲张中比I级精索静脉曲张中更常见，表现为左侧病变动脉灌注减少。结论是，使用连续图像和时间-活性曲线进行闪烁扫描分析不仅能高度代表临床可触及的精索静脉曲张的程度，还能更好地了解阴囊局部血流动力学。
