Excerpt
Single photon emission computed tomography (SPECT) myocardial perfusion imaging is widely used for evaluation of patients with known or suspected coronary artery disease. It is an accurate and reliable diagnostic method for evaluation of myocardial perfusion with approximately 90% sensitivity and nearly 80% specificity. Patient motion is one of the most common sources of artifacts during SPECT study, which can lower the specificity of the SPECT study. We present a case of a patient who had significant myocardial perfusion defect due to horizontal motion which significantly improved after motion correction of the raw data. …
