研究生:阿丽曼·巴生导师:秦永德

摘要

目的:探讨放射性核素阴囊血池显像技术(RSS)及性激素诊断精索静脉曲张(Vc)
及亚临床型精索静脉曲张(SVc)的指标筛选及其临床价值。方法:选取临床主诉及病
史提示精索静脉曲张或(和)有不育病史的患者 39 例,分别接受彩色双功能多普勒
血流显像(CDFI)和放射性核素阴囊血池显像(RSS),同时选取其中 25 例内分泌激
素测定患者,并取 23 例同时做性激素测定的非 Vc 患者。RSS 各指标与 CDFI 所测
量内径呈线性相关,以为诊断标准,RSS 各指标做 ROC 曲线分析,同时做
内分泌激素的 ROC 分析并做 T 检验。结果:阴囊计数与大血管计数之比曲线下面积
为 (阴囊计数与软组织计数之比曲线下面积为 );阴囊计数与大血管计数
比值大于为界可诊断精索静脉曲张,其灵敏度为 %,特异度为 %;同
时做特征性感兴趣区发现单侧精索静脉曲张曲线(Single Varicocele Curve,SVc)呈特
异性的“倒 V”波,双侧精索静脉曲张曲线(Double Varicocele Curve,DVc)呈特异的“M”
波,性激素当中 PRL 诊断价值较高,曲线下面积为 ,T 检验除睾丸***外其余 P
值均小于。结论:RSS 技术是诊断临床型及亚临床型的 Vc 简单、安全、有效的
无创方法,以为界诊断精索静脉曲张,结合特异性的 SVC 及 DVC 定性图像分
析对于提高核素阴囊血池显像的诊断价值具有及其重要的意义,同时可结合性激素
的测定进一步提高其检出率。

Curves(ROC)

Abstract

Objective: Assess the value of radionuclide scrotal Scintigraphy(RSS) and sex
hormone,select sensitive ratio for diagnosing and grading clinical varicocele(Vc) and
subclinical varicocele(SVc) by radionuclide scrotal scintigraphy (RSS) and sexhormone.
Methods: Scrotal scan and ultrasonograghy were performed for 39 infertile patients
with medical records plain of Vc . There was a high line-correlation between the
ratio of SBPI/(great vessel) and the diameter detected by ultrasound,we take as
diagnostic criteria ,then took the ratio of SBPI/RCV to make ROC analysis. Results:Area
undered curve made by SBPI/(great vessel) is (area under curve made by
SBPI/(soft tissue) is ; as cut-off value , sensitivity is %,and specificity is
%. ROI of scrotal and the great vessel has a special varicocele curve, single varicose
curve was found as “inverse V”, double varicocele
