Myocardial uptake of 99mTc-HDP and reduced perfusion on CT in subacute myocardial infarction.
A 65-year-old man with known bone metastases from prostate cancer and no cardiac history attended for a restaging bone scan (BS). Diffuse increased Tc-HDP activity in the heart was noted, new since a BS 3 months earlier. A restaging contrast-enhanced CT scan on the same day showed reduced myocardial perfusion in the anterior, apical, and septal walls. On direct questioning, he described an episode of severe exertional chest pain the day before. Myocardial infarction was confirmed and treated with primary percutaneous coronary intervention. New cardiac uptake on BS, raising the possibility of myocardial infarction, is a red alert for clinicians.
