Image quality and radiation exposure comparison of a double high-pitch acquisition for coronary computed tomography angiography vs standard retrospective spiral acquisition in patients with atrial fibrillation

Journal of Computer Assisted Tomography Jan 24, 2018

Prazeres CEED, et al. - In this original direct comparison, researchers assessed the relative image quality and radiation dose of coronary computed tomography (CT) angiography performed with dual-source CT scanner using 2 different protocols in patients with atrial fibrillation. Compared with the conventional spiral retrospective acquisition, a double high-pitch (DHP) spiral protocol for coronary CT angiography acquisition in patients with atrial fibrillation resulted in lower radiation exposure and superior image quality.
