Can CT angiography accurately quantify coronary artery calcification?

Quantifying coronary artery calcification from a contrast-enhanced cardiac computed tomography angiography study.
BACKGROUND: Cardiac computed tomography angiography (CCTA) is used for the assessment of coronary artery stenoses, whereas non-contrast ECG-gated computed tomography is commonly performed to quantify coronary artery calcium (CAC).

METHODS: a review was done of patients who underwent both non-contrast CT and CCTA.

RESULTS: 92 patients were identified. Correlation between non-contrast CT and CCTA was excellent (r = 0.96) for CAC scoring.

CONCLUSIONS: Quantification of CAC from a single contrast-enhanced CCTA scan is feasible and correlates well with non-contrast ECG-gated CT.
