Renal scanning is one of the imaging techniques used to investigate the upper urinary tract. In the present examination, the principles of performing renal scanning in the dog and car are described. Eleven animals with healthy kidneys (six dogs and five cats) were included in the study for the determination of normal scintigraphic findings as well as eight animals (seven dogs and one cat) with renal damage. The following nephropathies were investigated scintigraphically: nephrolithiasis, hydronephrosis, polycystic renal degeneration, renal aplasia, renal hypoplasia, obstruction of the ureter and renal trauma. Renal scanning proved to be easy to perform with acceptable effort in the dog and cat. It allows the simultaneous assessment of renal function on both sides during the phases of renal perfusion and tubular se- and excretion and represents a valuable adjunct to the morphologically orientated radio- and sonography. The nephrogram curves are comparable to those found in man, although the time until reaching the maximum of the curves and elimination half times are shorter. Also, the sequential scintigrams can be divided into the corresponding phases as in man. Through permanent technical development, today there are gamma processors at disposal that allow a faster, comprehensive and sophisticated evaluation. In the present investigation, this was demonstrated by a comparison of two different calculators. However, due to the financial and technical expenditures and the special radiological safety precautions required, renal scanning will be a technique reserved to larger clinics.
肾脏扫描是用于检查上尿路的成像技术之一。在本次检查中，描述了在犬类和猫类中进行肾脏扫描的原则。该研究纳入了11只肾脏健康的动物（6只犬和5只猫）以确定正常的闪烁扫描结果，以及8只患有肾脏损伤的动物（7只犬和1只猫）。对以下肾病进行了闪烁扫描研究：肾结石、肾积水、多囊性肾变性、肾发育不全、肾发育不良、输尿管梗阻和肾外伤。事实证明，在犬类和猫类中进行肾脏扫描操作简便，工作量可接受。它能在肾脏灌注、肾小管分泌和排泄阶段同时评估双侧肾功能，是形态学导向的放射学和超声检查的重要辅助手段。尽管达到曲线峰值的时间和消除半衰期较短，但肾图曲线与人类的相似。此外，连续闪烁图也可像人类一样分为相应阶段。通过不断的技术发展，如今有了可供使用的伽马处理器，能够进行更快、更全面和更精细的评估。在本次研究中，通过比较两种不同的计算器证明了这一点。然而，由于所需的资金和技术支出以及特殊的放射安全预防措施，肾脏扫描将是一项仅适用于大型诊所的技术。
