Exploring the Reliability of Compressed Sensing Cardiac MR Cine in Heart Failure: Evidence from Varied MR Field Strengths and Vendors

Motivation: The challenge of obtaining high-quality CMR cine images in patients with heart failure (HF) due to difficulties in breath-holding and arrhythmia. Goal(s): Explore the feasibility of utilizing compressed sensing cardiac cine with varying levels of acceleration to acquire comparable cine images in HF patients. Approach: We compare cardiac function, strain parameters, and image quality between bSSFP and CS images in both HF patients and healthy participants, utilizing MRI systems from different vendors. Results: Our findings demonstrate a high level of consistency in most cardiac function and strain parameters between the two sequences. CS cardiac cine images exhibit comparable quality to bSSFP images. Impact: This study offers prospective validation for the use of CS cardiac cine sequences in HF patients, addressing issues related to lengthy scanning durations and artifacts. It expands the eligible population for CMR scanning while optimizing image quality.
