Description
Summary:In order to evaluate the usefulness of volume mesurement of small organ using single photon emission computed tomography (SPECT), phantom study with six cylinder (1-50ml) and three thyroid phantoms (12-34 ml) with various 131I concentration were performed. The optimal threshold level was quite changed according of the shape, size of phantoms and 131I activity: small change of the threshold level resulted in considerable difference of the volume. The volume measurement of the small organ such as thyroid using SPECT might not accurate.
