Abstract

We present the case of a 65-year-old man with dyspnea and chest discomfort referred for dipyridamole myocardial perfusion scintigraphy. 99mTc-sestamibi cardiac gated SPECT images showed an irreversible hypoperfusion in the mid-ventricular portion of anteroseptal wall, a suspicious reversible hypoperfusion in the apical slices of inferolateral wall, and left ventricle dilatation with a ejection fraction of 40%. In addition, a decreased radiotracer uptake was seen in the posterior region of the left hemithorax in the rotating (cine) images of the stress and rest myocardial perfusion SPECT (Fig. 1). Also, the review of all the raw data demonstrated
