The number of diagnostic nuclear medicine procedures has grown in the fi rst few years of the new century. Nuclear cardiology has diversifi ed, stimulating development of new equipment and imaging protocols. Gated myocardial perfusion imaging completed with quantifi cation is now a standard procedure. Faster computers have led to improved reconstruction techniques, higher image quality, increased patient throughput and more automated acquisition and processing protocols. In addition, automated processing and reporting and tele-radiology have made higher workloads possible despite the decreasing amount of money available
