Abstract

Abstract: False-negative results of coronary artery calcium score (CACS) are common due to small calcified lesions being missed using a 3-mm slice thickness, a threshold of 130 Hounsfield units (HU) and a minimum area of 1 mm 2 for defining a calcified plaque. In contrast, false-positive results of CACS, as verified by a lack of coronary artery calcifications in computed tomography coronary angiogram (CTCA), are extremely uncommon. We present a patient with a false-positive coronary calcium score who had normal coronary arteries in CTCA.
