Diagnostic Merits of Current and Potential Applications of Single Photon and Positron Imaging: A Perspective

摘要

A brief review of the limitations of medical radionuclide imaging techniques in competition with x-ray CAT scanning and ultrasound suggest that the emphasis in this are should be on measurement of the physiologic uptake of tracer materials. Tomography greatly improves the possibilities of quantitation of this uptake - examples using positron and single photon techniques are presented for exp 13 NH sub 3 and exp 201 Tl in the heart.
