A simple method for determining isotope uptake in disseminated metastatic thyroid disease.

A simple method for determining isotope uptake in disseminated metastatic thyroid disease is described. This method can be adopted by a nuclear medicine department which has no on-line computer for acquisition and handling of images from a gamma camera. The equipment needed is the gamma camera, a storage device for images (analog or digital), and an option to define regions of interest and their count rate. Today this option is available in any standard gamma camera. The method is outlined by a specific example of a clinical case.
