Incidental Findings on Myocardial Perfusion SPECT Images.

Myocardial perfusion SPECT plays a crucial role in the diagnosis of coronary artery disease, providing a noninvasive tool to monitor ischemia and infarction. The findings can have a profound impact on diagnosis and management in these patients. However, incidental noncardiac findings on myocardial perfusion SPECT images can also affect management. These noncardiac subtleties are most often detected on the rotating raw SPECT images, which are often overlooked. The intent of this pictorial essay is to illustrate several subtle noncardiac abnormalities within nuclear cardiac imaging that can have an impact on patient management and follow-up.
