Feasibility of alternative trigger deletion to improve 64-slice coronary computed tomography angiography quality in patients with increased heart rate.

ABSTRACT:

Background

A high heart rate (HR) increases motion artifacts in coronary computed tomography angiography (CCTA). This retrospective study aimed to investigate the feasibility of using a novel electrocardiogram (ECG)-edit technique involving alternate trigger deletion to improve the quality of 64-slice CCTA images in patients with increased HR.

Methods

This retrospective single-center study enrolled 53 symptomatic cardiac patients with increased HR (≥75 beats per minute). CCTA was acquired on a 64-slice computed tomography (CT) scanner using a retrospective ECG-gated acquisition protocol. Images were reconstructed without the ECG-edit function, and with the ECG-edit function of alternate trigger deletion. Two experienced radiologists evaluated the subjective image quality of
