Determination of Thyroid Gland Mass Using the Scintillation Camera and Computer

Abstract

A scintillation camera-computer method for determining thyroid gland mass prior to ¹³¹I therapy for Graves’ disease is described. The method was developed to replace an older rectilinear scanner technique previously used. The two methods were compared and the scintillation camera-computer method was found to have a small standard error of the estimate and a high degree of correlation with the rectilinear method.
