Artifacts and normal variants are a significant source of false-positive interpretations of myocardial perfusion single-photon emission computed tomography (SPECT). This chapter discusses how, by anticipating and recognizing such findings, the astute technologist and interpreting physician can increase test specificity in the diagnosis of coronary artery disease and avoid unnecessary catheterization of normal patients.
