Abstract

We explored whether intracycle motion correction algorithms (MCAs) might be applicable to dual energy computed tomography coronary angiography in patients with intermediate to high likelihood of coronary artery disease. MCA reconstructions were associated with higher interpretability rates (96.7% vs. 87.9%, P< .001), image quality scores (4.12±0.9 vs. 3.76±1.0; P< .0001), and diagnostic performance [area under the curve of 0.95 (95% confidence interval [CI] 0.92–0.97) vs. 0.89 (95% CI 0.86–0.92); P< .0001] compared to conventional reconstructions. In conclusion, application of intracycle MCA reconstructions to dual energy computed tomography acquisitions was feasible and resulted in significantly higher image quality scores, interpretability, and diagnostic performance.
