Fast multimodal exams are required in many situations such as acute ischemic stroke and brain trauma. Recently a multicontrast full brain protocol was proposed based on single shot echo-planar imaging (SS-EPI). However, the SS-EPI images suffer from distortion artifacts. In this work, we provide a speedy multi-contrast distortion-free imaging protocol including T2w, DWI, T2*w, T1 FLAIR and T2 FLAIR based on point spread function encoded echo-planar imaging (PSF-EPI).
