概要

Regarding cardiac nuclear medicine, we have reviewed how diagnostic imaging has until now been supported the technological side, and have searched for solutions concerning the problems that have yet to solved. As regards the cardiac function tests, the multi-triggered data acquisition was investigated, and regarding image analysis, we have come up with a fully automated method to determine the left ventricular contour. Furthermore, concerning myocardial examinations, SPECT technology was used, enabling a more accurate detection of the lesions than by using the existing planar imaging technique. With the image analysis, we could develop left ventricular long-axis tomography in which cardiac morphology remains unchanged. On the other hand, with the development of radiopharmaceutical photos of the myocardial energy metabolism and its receptors, which now provide a useful means for detecting. Future problems regarding SPECT technology seems to center on how to remove the scattered rays and how to correct the attenuation effect. More research in this area is needed.
