A new technique, 3D-EPTI with inversion-recovery-prepared gradient- and spin-echo readouts, was developed to rapidly acquire a time-series of distortion- and blurring-free multi-contrast images. The technique relies on a new ‘time-resolved’ multi-shot 3D-EPI readout with a hybrid spatio-temporal CAIPI and golden-angle radial-blade sampling scheme. With just about 2 minutes of 3D-EPTI acquisition, thousands of brain volume data at 1.1 mm isotropic resolution can be generated at different TIs and TEs, capturing signal evolution of T1 inversion recovery interspersed with T2/T2* decay, enabling rapid simultaneous quantitative parameters estimation.
