This study presents accelerated quantification of the ultrashort-T2 components in the brain with approximately 4-fold reduction in scan time. Retrospective undersampling across 5 healthy volunteers showed strong correlations between the ultrashort-T2 component amplitude, relaxation times, and frequency shifts between 8 TE and 32 TE datasets, showing that it is possible to rapidly obtain high quality images of brain ultrashort T2 components that are associated with myelin membrane protons.
