Key Points

VPAL reduced reconstruction time from 16.3 hours to 4.7 hours compared to ADMM, indicating a significant improvement.
Relative errors for VPAL and ADMM were similar, with p-values suggesting no significant difference in accuracy.
Blood-myocardium sharpness and LVEF values were close, reflecting consistent functional assessment between VPAL and ADMM.
Both VPAL and ADMM received high diagnostic ratings, supporting their use in clinical imaging contexts.

Implication

Variable projection augmented Lagrangian (VPAL) significantly lowers reconstruction time in CMR, suggesting improved clinical feasibility and comparable image quality to ADMM.
