The measurement of administered tracer dose by scanning the entire body and totalizing the counts accumulated by each detector has proven to be a reliable determination of TBR. In 14 carefully controlled studies with collection of stools and urines using different isotopes (Ca-47, Sr-85, 1-131, Fe-59), the HEG scanner gave results which were within 5 per cent of the retention measured by radioactivity assay of excretions (Fig. 1). The ten calcium-47 studies were measured at numerous times and followed for a maximum of 22 days; the two strontium-85 studies were followed for 16 days; the three iodine-131 patients up to 10 days and the iron-59 patient up to 4 days. Outpatients have been checked for strontium-85 retention with the HEG scanner for as long as one and a half years. Monthly 24 hour urine collections and body point measurements on these patients have indicated the TBR measurements to be accurate presentations of Sr-85 turnover in the body.
