巯甲丙脯酸介入^（99m）Tc－MAG_3肾图诊断肾血管性高血压的临床评价

EVALUATION OF CAPTOPRIL RENOGRAPHY WITH^(99m)Tc-MAG_3 IN THE DIAGNOSIS OF RENOVASCULAR HYPERTENSION

８１例高血压患者分别作基础肾图及巯甲丙脯酸（ＣＡＰ）介入^（９９ｍ）Ｔｃ－巯乙酰二甘氨酸（ＭＡＧ_３）肾图，其中２５例与肾动脉造影对照．结果表明ＣＡＰ介入前敏感性为６６％，特异性为３３％；ＣＡＰ介入后敏感性为７２％，特异性为１００％．故用ＣＡＰ介入^（９９ｍ）ＴＣ－ＭＡＧ_３肾图筛选和诊断肾血管性高血压具有简单、无创、比较敏感和特异性高的特点，适合无γ相机的医院常规应用．

Abstract patients with suspected renovascular hypertension(RVH)were studied with^(99m)Tc-MAG_3 renography before and after administration of 25mg captopril(CAP).25 out of 81 cases were proved by renal arteriography or DSA. The results showed that by using CAP,the sensitivity and specificity of renography in the diagnosis of RVH increased from 66% to 72% and 33% to 100%,respectively.We concluded that renography is a simple,noninvasive,sensitive,specific method for screening RVH and is suitable for hospitals which have no γ-camera.
