Implication

Clinical study demonstrates reduced motion artifact and reliable coronary calcification imaging in 26 patients, indicating spiral CT feasibility for screening without hardware changes.

Key Points

To assess a retrospective cardiac-gated postprocessing technique designed to minimize cardiac motion artifacts during spiral computed tomography of the coronary arteries.
Evaluated a retrospective cardiac-gated postprocessing algorithm requiring no modifications to CT scanner hardware or software.
Applied the postprocessing protocol to spiral CT examinations performed in 26 patients.
Retrospective gating reduced cardiac motion artifacts and allowed consistent visualization of the coronary arteries across the cohort.
Quantification of coronary artery calcification was successfully achieved in patients presenting with prominent calcified deposits.
