Organ volume was experimentally and clinically determined using single photon emission computed tomography (SPECT). In organ phantom filling with 99mTcO4-, the error was less than 3.3% in the volume over 400 ml but 11% at 200 ml. In 28 cases of patient, liver and spleen volume were measured by SPECT and X-CT. Good correlation was founded between SPECT volume and X-CT volume (r = 0.99, n = 49), although SPECT volume were 16% higher than X-CT volume (y = 1.16 x + 11.6, x: X-CT volume, y: SPECT volume).
使用单光子发射计算机断层扫描（SPECT）对器官体积进行了实验和临床测定。在填充99mTcO4-的器官模型中，超过400 ml的体积误差小于3.3%，但在200 ml时为11%。在28例患者中，通过SPECT和X-CT测量肝脏和脾脏体积。尽管SPECT测量的体积比X-CT测量的体积高16%（y = 1.16x + 11.6，x：X-CT测量的体积，y：SPECT测量的体积），但SPECT测量的体积与X-CT测量的体积之间存在良好的相关性（r = 0.99，n = 49）。
