AI-developed fat attenuation index (FAI) scores from noncontrast CT improve prediction of cardiovascular risk beyond traditional calcium scoring.
Key Details
- 1AI used to derive fat attenuation index (FAI) scores from noncontrast cardiac CT scans.
- 2FAI scores outperform or match prognostic value of coronary artery calcium (CAC) scoring and established CCTA measures.
- 3Study included 6,818 individuals in a development cohort and 19,110 in a validation cohort.
- 4Median follow-up was 6.7 years, capturing 536 cardiovascular deaths and 1,727 major adverse cardiovascular events (MACE).
- 5Findings suggest individuals with zero or low CAC can still be identified as high risk via FAI.
Why It Matters
This technique could change risk stratification for cardiovascular disease, offering non-contrast, AI-driven alternatives that may detect risk in patients otherwise missed by calcium scoring alone. It supports expanded uses for noncontrast CT and highlights AI’s growing clinical relevance in radiology.
