目的:探讨放射性核素阴囊血池显像(RSI)技术诊断精索静脉曲张(VC)的价值。方法:本组126例有男性不育1年以上病史、精液分析异常的患者分别接受临床体格检查(PE);RSI技术检查,计算两侧阴囊血池指数值(SBPI),并观察是否有精索静脉血液返流;以及彩色双功能多普勒显像(CDFI)检查,对VC进行分型、定度。将PE,RSI结果分别与CDFI结果对比。结果:PE、RSI诊断VC的灵敏度分别为:71.7%、96.5%,特异度分别为:69.1%、97.1%。RSI诊断VC的灵敏度、特异度均高于PE。结论:RSI技术是诊断临床型、亚临床型VC的简单、安全、有效的无创诊断方法,也是一种非侵袭性,更加客观、准确地诊断VC的有效方法。
Objective: To investigate the value of radionuclide scrotal blood pool imaging (RSI) in the diagnosis of varicocele (VC). Methods: 126 patients with male infertility over 1 year history and abnormal semen analysis underwent physical examination (PE) respectively. The RSI technique was used to calculate the scrotal blood pool index value (SBPI) Rope venous blood reflux; and color bi-functional Doppler imaging (CDFI) examination, VC typing, fixed. Compare PE and RSI results with CDFI results respectively. Results: The sensitivities of PE and RSI in diagnosing VC were 71.7% and 96.5% respectively, and the specificity were 69.1% and 97.1% respectively. RSI diagnosis of VC sensitivity, specificity are higher than PE. Conclusion: RSI is a simple, safe and effective noninvasive diagnostic method for clinical and subclinical VC. It is also a noninvasive and effective method to diagnose VC more objectively and accurately.
