    Description

    A reverse redistribution pattern in rest thallium-201 (Tl)/stress technetium-99 m (Tc) tetrofosmin single photon emission CT (SPECT) is confusing. We present a myocardial perfusion SPECT in a 40-year-old patient undergoing coronary intervention in the left anterior descending coronary artery with an acute coronary syndrome. This pattern depicts a nearly normal perfusion in a resting Tl image and a perfusion defect in a stress Tc image, which indicates stress-induced ischaemia without significant coronary stenosis. This is frequently seen in …
