Liang J, et al. - The impact of a motion-correction algorithm was examined on diagnostic accuracy of coronary computed tomography angiography (CCTA) within 1 heart beat in patients with high heart rate (HR) using a 256-row detector CT. In patients with high HR, coronary computed tomography angiography could be performed within 1 heart beat yielding low radiation dose. Significant improvements were achieved in image quality and diagnostic value by using SSF technique reconstruction for 1 heart beat CCTA.
