Highly Accelerated Real-time Cine MRI Pulse Sequence for Cardiac Implantable Electronic Devices and Arrhythmias.

ABSTRACT: Purpose To compare the image quality and temporal resolution of a 32-fold accelerated real-time cine MRI pulse sequence (19.3-msec temporal resolution) with those of a previously described 16-fold accelerated Cartesian real-time cine sequence (39.8-msec temporal resolution) in patients with cardiac implantable electronic devices (CIEDs) and arrhythmias. Materials and Methods This retrospective study included patients with CIEDs and arrhythmias scanned using both radial and Cartesian real-time cine MRI pulse sequences with gradient-recalled echo readouts at 1.5 T from March 2022 to March 2024. Image quality was assessed visually by clinical raters using a five-point Likert scale for each of four categories (namely, conspicuity, temporal fidelity of wall motion, artifact, and noise) and quan
