Summary

Coronary computed tomography angiography (CCTA) is a frequently performed test for the diagnosis and/or exclusion of coronary artery disease (CAD) in appropriately selected patients. The performance of non-contrast computed tomography for the detection and quantification of coronary calcification is typically performed prior to CCTA in an effort to identify significant calcification which may influence subsequent data acquisition during the CCTA. However, performance of calcium scoring adds significant radiation and most coronary calcification is proximal in its location, potentially visualized using a focused non-contrast scan.

The purpose of this study is to prospectively compare the usefulness of a modified non-contrast CT, using a significantly shorter scan length and lower radiation parameters, as compared to standard coronary artery calcium scanning for the detection of coronary calcification that may influence subsequent CCTA performance.
