BLAST accelerates dynamic contrast-enhanced lung imaging with only limited
penalty in RMS error. Yet its restrictions including initial-overshooting and
temporal-smoothing cast uncertainties on perfusion quantifications and
corresponding studies. This work shows that while those restrictions influence intensity estimation on patient
images as predicted, little impact is inflicted on the corresponding
perfusion quantification, suggesting feasibility of accelerated lung images
in clinical studies.
