Coronary artery calcification on low-dose chest CT is an early predictor of severe progression of COVID-19—A multi-center, multi-vendor study

Quantification of coronary artery calcification.
Exemplary axial computed tomography slice of a patient with evidence of coronary artery calcification (a). Connected voxels with an attenuation above 130 HU and minimum volume of 0.5 mm3 were highlighted by the vendor’s software (b). Coronary artery plaques were manually selected, excluding aortic valve calcifications, e.g., calcification of the Ramus interventricularis anterior (white arrowheads). The Agatston score was noted for each patient.
