Clinical application of free-breathing compressed sensing in cardiac magnetic resonance cine sequences for assessing left ventricular function and strain.

ABSTRACT:

Background

Cardiac magnetic resonance (CMR) is essential for evaluating cardiac function but is limited by its long scan times and the requirement for breath-holding. This has prompted the development of accelerated techniques such as compressed sensing (CS); however, most studies on CS have been conducted under breath-hold (BH) conditions. Thus, this study aimed to investigate the feasibility of CMR cine with free-breathing (FB) CS by comparing the left ventricular (LV) function and strain parameters of this technique with those obtained using conventional BH cine.

Methods

Thirty-four patients who underwent CMR examination at Tongji Hospital were prospectively enrolled in this study from January 2023 to August 2023. All patients underwent cardiac short-axis and four-chamber
