Synopsis

Keywords: Arrhythmia, Visualization

Motivation: Standard ECG-gated breath-held (BH) cine MRI often produces non-diagnostic image quality in CIED patients who have a high burden of arrhythmia.

Goal(s): The goal of this study is to produce diagnostic images using a free-breathing real-time cine MRI for those patients.

Approach: We proposed a new pulse sequence to meet our goal.

Results: Our proposed pulse sequence produced clinically acceptable images and accurate bi-ventricular and functional parameters compared with standard BH cine in patients with a CIED.

Impact: Our proposed pulse sequence will be useful for a shorter overall scan time while maintaining a diagnostically acceptable images in all CIED patients.
