Description
Summary:Abstract 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.
