WebJul 31, 2015 · A SPECT scan of the heart is a noninvasive nuclear imaging test. It uses radioactive tracers that are injected into the blood to produce pictures of your heart. Doctors use SPECT to diagnose coronary artery disease and find out if a heart attack has occurred. SPECT can show how well blood is flowing to the heart and how well the heart is working. WebSPECT image quality also can be optimized by proper camera set-up and patient positioning noting that spatial resolution is best when the patient is as close to the collimator face as possible. 5 Image noise also affects the overall image quality, and using more photons to form the image lowers the noise and improves image quality.
