分别测定双肾功能对肾脏病患者早期诊断和随访是很重要的,虽已有许多方法,但各有欠缺难以推广.~(99m)Tc-DMSA是一个评价肾皮质功能的实用指标.从大量的动物模型研究显示,SPECT用阈值功能测定~(99m)Tc-DMSA浓度,并发现肾模型中的实际放射性与SPECT所测得的放射性其相关性很好.研究证明,用SPECT定量肾脏摄取DMSA的指数是能分别测定肾功能的准确指针.材料方法:20例患者均经静脉泌尿系造影术和~(99m)Tc-DTPA闪烁照像确诊只有一侧肾脏.受检者
It is very important to determine the function of renal function separately for the early diagnosis and follow-up of patients with kidney disease.Although there are many methods, it is difficult to popularize the renal function. ~ (99m) Tc-DMSA is a practical indicator to evaluate the function of renal cortex, Animal model studies have shown that the SPECT threshold function determination of ~ (99m) Tc-DMSA concentration and found that the actual radioactivity in the renal model and radioactivity measured SPECT good correlation studies have shown that the use of SPECT quantitative kidney uptake of DMSA Of the index can be used to determine the exact function of the kidney.Materials and Methods: Twenty patients were diagnosed by intravenous urography and ~ (99m) Tc-DTPA scintigraphy only one side of the kidney.
