From: Intracranial internal carotid artery calcification is not predictive of future cognitive decline
Internal carotid artery (ICA) calcification in low resolution CT scans for two participants. a, b Participant A demonstrates calcifications in the carotid siphon (total Agatston score: 1256). In participant B (c, d), calcifications are demonstrated in the petrous (c) and cavernous (d) segments of the left ICA (total Agatston score: 763). Mild ICA calcification is demonstrated in e–f in participant C with a total Agatston score of 150
