title: [Comparative investigations of osteotropic radiopharmaceuticals. V. Demonstration of abnormal uptake with various scanners (author's transl)].
abstract: Experiments with phantoms have shown that there is a higher probability of showing areas of increased uptake when using a camera than with a scanner. In 49 patients with suspected bone metastases, scans were performed during their pre-operative work-up, under identical conditions, using a whole body scintigraphic scanner with a 5-inch double head and a scintillation camera with total body facility. The scintillation camera showed a significantly higher sensitivity to bone metastases, but there was no difference in the pick-up rate of distant metastases. Despite the possibly more frequent use of the camera, its cost is no higher than that of the scanner. Both on diagnostic and economic grounds, we consider the scintillation camera, with a total body facility, to be the instrument of choice for total skeleton scintigraphy.
