[Measurement of the liver and spleen volume by single photon emission computed tomography].
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).
