To evaluate radionuclide scrotal imaging (RSI) in the diagnosis of varicocele.
We performed physical examination (PE) and RSI for 126 patients with infertility for at least 12 months and seminal abnormality, obtained the scrotal blood-pool index (SBPI), observed the reflux in the spermatic vein during RSI, typed and graded varicocele by color Doppler flow imaging (CDFI) and compared the results of PE and RSI with those of CDFI.
The rates of sensitivity and specificity of RSI in the diagnosis of varicocele (96.5% and 97.1%) were both higher than those of PE (71.7% and 69.1%).
Simple, accurate and noninvasive, RSI is an effective method for the diagnosis of clinical and subclinical varicocele.
评估放射性核素阴囊显像（RSI）在精索静脉曲张诊断中的价值。
对126例不育且精液异常至少12个月的患者进行体格检查（PE）和RSI，获取阴囊血池指数（SBPI），观察RSI期间精索静脉的反流情况，通过彩色多普勒血流成像（CDFI）对精索静脉曲张进行分型和分级，并将PE和RSI的结果与CDFI的结果进行比较。
RSI诊断精索静脉曲张的敏感度和特异度（分别为96.5%和97.1%）均高于PE（分别为71.7%和69.1%）。
RSI简单、准确且无创，是诊断临床型和亚临床型精索静脉曲张的有效方法。
