INTRODUCTION: We sought to validate whether low dose CACS CT with hybrid IR (HIR) could replace standard dose filtered back projection (FBP).

METHOD: We enrolled 100 patients to undergo low dose CACS CT with HIR, in addition to routine full dose FBP.

RESULTS: No significant difference between full and low dose CT in Agatston score 138.2±360.6 vs. 137.3±356.4 (p=0.272) or calcium mass score 19±48.3 vs. 18.7±49 (p=0.8), respectively. Bland-Altman analysis showed no systematic bias. Calcium volume difference was statistically significant 57.2±134 vs. 55.1±130.2 (p=0.001).

CONCLUSION: Low dose CT for calcium scoring with HIR enables stable CACS Agatston score and calcium mass quantification as compared to full dose FBP.
