Extract

There are many methods for evaluating left systolic ejection fraction and regional wall motion. Gated single photon emission CT (SPECT) imaging is the most frequently used method used in nuclear cardiology for estimating ejection fraction. The majority of nuclear cardiology laboratories in the United States perform gated SPECT imaging routinely in all patients who are referred for myocardial perfusion imaging, with an estimate of > 90% of all images acquired with gated SPECT. It takes minimal additional effort to obtain gated images without the need for additional hardware or an increase in image acquisition times while providing important additional clinical information.
