EPIMix is a multi-contrast MRI sequence that can produce T1-FLAIR, T2w, T2*w, T2-FLAIR, DWI, ADC images of the brain in about 70 s. To make EPIMix closer to a single-scan brain MRI exam, we propose optional supplemental sequence modules. The add-on sequences include T2w SMS FSE Propeller (distortion free), 3D SWI-EPI, and 3D T1w SPGR-EPI (isotropic resolution), which all have higher resolution and less distortions compared to EPIMix. With this extension to EPIMix, nine images series can be produced in 3 min total scan time.
