Emerging evidence In an issue of Circulation: Cardiovascular Imaging, Xie et al.1 performed a systematic review and meta-analysis to validate the prognostic importance of CAC scoring in non-triggered thoracic CT. The authors of this study performed a meta-analysis of five studies that compared CAC obtained using non-gated CT scans versus gated CT scans. This study demonstrated an excellent correlation between the two techniques with a pooled Cohen κ agreement being 0.89 (95% confidence interval [CI] 0.83–0.95). While this is promising, the authors have also highlighted some discrepancy between the two techniques, and this is important to
