This study examines the performance of functional lung MRI using matrix pencil (MP) decomposition for the estimation of regional fractional ventilation and perfusion by exploring the relationship between the scanning time and the quantitative outcomes. Our results show excellent promise that the overall scan time for functional lung imaging using MP decomposition can be considerably shortened, which can allow for easier integration of MP MRI in clinical routine protocols.
