Key result
Compressed sensing cardiac magnetic resonance cine sequences acquired during breath-hold or free-breathing showed almost perfect agreement with standard SSFP for detecting regional wall motion abnormalities (kappa 0.918 and 0.868, p<0.001).
Why the study?
Does compressed sensing cine CMR (breath-hold or free-breathing) allow reliable detection of regional wall motion abnormalities compared to standard SSFP in patients undergoing clinical CMR?
Observational (n=50)
No
Does compressed sensing cine CMR (breath-hold or free-breathing) allow reliable detection of regional wall motion abnormalities compared to standard SSFP in patients undergoing clinical CMR?
Compressed sensing cine CMR acquired during breath-hold or free-breathing provides reliable detection of regional wall motion abnormalities with almost perfect agreement to standard SSFP, offering a faster alternative for LV function assessment.
May enable shorter CMR exams for RWMA assessment; supports compressed sensing validation but remains hypothesis-generating.

Goebel et al. (2018) conducted an observational in Suspected heart disease (n=50). Compressed sensing CMR sequences (sparse_HB and sparse_FB) vs. Standard SSFP sequence was evaluated on Agreement in regional wall motion abnormalities (RWMA) detection between standard SSFP and sparse_HB (kappa 0.918, p=<0.001). Compressed sensing cardiac magnetic resonance cine sequences acquired during breath-hold or free-breathing showed almost perfect agreement with standard SSFP for detecting regional wall motion abnormalities (kappa 0.918 and 0.868, p<0.001).
