From: Clinical value of resting cardiac dual-energy CT in patients suspected of coronary artery disease
Match between coronary stenosis severity and resting DE-CTP. Curved multiplanar reconstruction CCTA reveals obstructive coronary artery disease with severe stenosis in RCA (A), LAD (B) and LCX (C). D Resting DE-CTP shows myocardial perfusion defects in anteroseptal, anterolateral, inferior walls and a subendocardial perfusion defect in inferolateral wall. This 63-year-old male subsequently underwent invasive coronary angiography (F–H) and PET (I) which confirmed the DE CT results. E, J are three-dimensional volume rendering technique (3D-VRT) and three-dimensional maximum intensity projection (3D-MIP) of CCTA respectively. DE-CTP = dual-energy CT perfusion; CCTA = coronary CT angiography; RCA = right coronary artery; LAD = left anterior artery, LCX = left anterior descending; PET = positron emission tomography
