Key result
Real-time free-breathing cardiovascular magnetic resonance with retrospective reconstruction yielded similar short-axis image quality scores (4.54 vs 4.52, P=0.756) compared to traditional breath-held segmented acquisitions.

Absolute Event Rate: 4.54% vs 4.52%
p-value: p=0.756
Real-time free-breathing CMR with retrospective reconstruction yields comparable image quality and volumetric measurements to traditional breath-held segmented CMR, offering a potential alternative for patients unable to hold their breath.
Xue et al. (2013) conducted a cross-sectional in Healthy volunteers (n=15). Real-time free-breathing cine CMR with retrospective reconstruction vs. Traditional segmented breath-held cine CMR was evaluated on Image quality score for short axis slices (high matrix size 256x144) (p=0.756). Real-time free-breathing cardiovascular magnetic resonance with retrospective reconstruction yielded similar short-axis image quality scores (4.54 vs 4.52, P=0.756) compared to traditional breath-held segmented acquisitions.
