About

This work suggests a methodology to adapt the injected radionuclide activity to the level of attenuation of each patient. The investigators propose a dose reduction adapted to the patient's weight, with no significant degradation of the image quality, in order to improve patients and staff radioprotection, standardize the image quality for easier clinical interpretation, and lead to radiopharmaceutical saving in the context of myocardial perfusion Imaging.
