Abstract
Aartifactual inferior wall defects of perfusion are a source of freque nt concern during Tl-201 exercise stress redistribution SPECT imaging in the supine position. These artifactual changes also affect Tc-99m s estamibi dipyridamole myocardial perfusion studies with supine SPECT y ielding a specificity of only 58% for right coronary artery (RCA) dise ase. Complementary SPECT prone imaging will enhance this specificity f or inferior wall abnormalities to 79% (P < 0.05) and is recommended fo r more accurate assessment of RCA stenosis, whether the patient challe nge is pharmacological or by exercise.
