Optimizing coronary computed tomography angiography image quality with motion-compensated reconstruction: a prospective electrocardiogram-triggered mode with second-generation dual-layer spectral detector computed tomography.

ABSTRACT:

Background

The recently developed motion-compensated reconstruction (MCR) algorithm provides a fully automated process to generate motion-corrected images. This study aimed to assess the image quality and radiation dose of prospective electrocardiogram (ECG)-triggered coronary computed tomography angiography (CCTA) using MCR on second-generation dual-layer spectral detector computed tomography (DLCT), and to investigate the influence of heart rate (HR) on the motion-correction effect of this algorithm.

Methods

This prospective study enrolled 73 patients who underwent CCTA on DLCT utilizing prospective ECG-gating. Patients were divided into two subgroups with a regular rhythm HR of <75 bpm and HR of ≥75 bpm and/or an irregular heart rhythm, respectively. Both subjective and o
