Abstract The purpose of this study was to evaluate the feasibility of a method that would use 59Fe quantitative sequential scintigrams together with a few blood samples in place of conventional ferrokinetic studies. To quantitate the efficiency of erythropoiesis or iron deposition sites, the radio-iron blood activity was subtracted by means of a whole body scanning with 99mTc-labelled erythrocytes. The study was performed on 31 patients (36 examinations) and regions of interest were drawn by three physicians on the sacral bone, the liver, the spleen and the femoral bone. To assess the physical feasibility of the scintigraphic method, correlation coefficients were computed between the number of counts of the 59Fe and 99mTc images and the corresponding 99mTc and 59Fe activities. To assess the clinical feasibility, the consistency of the data resulting from the drawing of the ROIs was verified and those of conventional ferrokinetics were introduced and their consistency verified. These assessments suggest that the scintigraphic method can be used in place of the conventional external counting method.
