CT-based abdominal vascular calcification: quantification and risk assessment

Abdominal vascular calcification on routine CT is a marker of systemic atherosclerotic burden, with semiquantitative (Agatston, volume) and length-adjusted metrics aiding risk stratification for cardiovascular events, renal dysfunction, and mortality. Standardization and AI vali…

• Scoring methods include Agatston-based, volume-based, and length-adjusted metrics for abdominal aorta and major branches.
• Calcification is associated with cardiovascular events, renal dysfunction, mesenteric ischemia, peripheral arterial disease, and perioperative complications.
• AI-based automated quantification could enable scalable screening but requires standardized definitions, external validation, and outcome-based endpoints.
