Myocardial Perfusion Imaging: Always Evolving
Myocardial perfusion assessed by nuclear medicine began to be used in clinical practice in the 1970s with the radiotracer 201-thallium chloride in two-dimensional images.
Advances in the development of equipment, from the possibility of three-dimensional images by single-photon emission computed tomography (SPECT), and new tracers, such as those linked to 99-technetium, have allowed the consolidation of nuclear cardiology as a non-invasive tool with high diagnostic accuracy in the context of coronary artery disease.
