Noninvasive diagnosis of renovascular hypertension using nuclear medicine techniques has evolved in the past 30 years through improvements in imaging equipment, radiotracers, and, most recently, captopril intervention. Characteristic patterns of normal and abnormal renograms using typical radiotracers are demonstrated, including renal artery stenosis. Comparison with other tests, both invasive and noninvasive, are made with the aim toward identifying anatomic as well as physiologic definitions of renovascular hypertension. Pitfalls in the methodology are also described. The main advantage of captopril renography is enhancement of the sensitivity, and particularly the specificity, of the radionuclide diagnosis of renovascular hypertension. Available investigations have identified captopril renography as the likely procedure of choice in the noninvasive identification of renovascular hypertension.
在过去30年里，利用核医学技术对肾血管性高血压进行无创诊断已取得进展，这得益于成像设备、放射性示踪剂的改进，以及最近卡托普利介入技术的发展。展示了使用典型放射性示踪剂时正常和异常肾图的特征模式，包括肾动脉狭窄。将其与其他有创和无创检查进行比较，目的是确定肾血管性高血压的解剖学和生理学定义。还描述了该方法中的陷阱。卡托普利肾图的主要优点是提高了肾血管性高血压放射性核素诊断的敏感性，尤其是特异性。现有研究已将卡托普利肾图确定为无创诊断肾血管性高血压可能的首选检查方法。
