The Agatston score for each calcified lesion is a function of the CAC area and the maximal CAC density. The total Agatston score is a simple sum of all CAC lesions. ∗∗Contiguous voxels >130 HU are defined as a calcified lesion. The score for an individual lesion is derived by ...

Purpose: Detection and quantification of coronary artery calcium (CAC) has a prognostic value for future cardiovascular events, beyond that accrued from other cardiovascular risk factors. CAC is conventionally measured as an Agatston score from an EKG-gated non-contrast CT of the heart using special...

Recent work has automated such task with deep learning techniques, even skipping the segmentation step and performing a direct regression of the Agatston score. We study the effect of the choice of the loss function in such methodologies. We use a large database of 6983 CT scans to which the...
