SPECT in Recent-Onset Angina


Stress and rest images from single-photon emission computed tomography (SPECT) of a 52-yr-old man with recent-onset angina. Images obtained during stress show a large area of ischemia in the territory fed by the left anterior descending (LAD) artery that is absent at rest. Angiography confirmed a 95 to 99% occlusion involving the bifurcation of the LAD at the first diagonal branch.
