Tl-201 Scintigraphy in Multivessel Exercise-Induced Variant Angina

Abstract
A 53-year-old man presented for evaluation of nocturnal chest pain, consistent with angina pectoris. An exercise stress test reproduced his symptoms, however, exercise electrocardiograms were nondiagnostic. An exercise-thallium perfusion study confirmed vasospasm as the cause. This knowledge guided subsequent successful medical therapy.
