Abstract

Renal parenchymal volume is important for clinical interpretation. The phantom study was carried out to validate the volume calculation. The volume of kidney phantom was determined using reoriented single photon emission computed tomography (RSPECT). The phantom volume range was 20-300 ml. There are two major factors in the determination of volume which are radioactivity concentration and organ/background ratio. Our results showed that the effect of radioactivity concentration on the volume in the kidney phantom is -3.3 to 7.5% whereas the effect of organ/background ration was only 2.2%. Our relative volume deviation, therefore, from the real volume was 1.43%. We concluded that it is feasible to use kidney volume in clinical work.

摘要

肾实质体积对于临床诊断很重要。进行了体模研究以验证体积计算。使用重新定位的单光子发射计算机断层扫描（RSPECT）确定肾脏体模的体积。体模体积范围为20 - 300毫升。确定体积有两个主要因素，即放射性浓度和器官/本底比值。我们的结果表明，放射性浓度对肾脏体模体积的影响为 - 3.3%至7.5%，而器官/本底比值的影响仅为2.2%。因此，我们与实际体积的相对体积偏差为1.43%。我们得出结论，在临床工作中使用肾脏体积是可行的。
