A 68-year-old male patient, with a known history of coronary artery disease, was referred to our hospital due to unclear chest pain. Previously the patient had undergone percutaneous coronary angioplasty with stent placement. An adenosine-stress myocardial perfusion MRI was performed revealing no perfusion defect. Thereafter, the patient was referred for a coronary CT angiography with adenosine-stress myocardial perfusion using Dual Energy CT (DECT) mode.
