Multiplexed-EPI is performed using different number of images readout simultaneous in the EPI echo trains. Compared in whole brain imaging, slice accelerations (M) of 6 to 48 images per echo train were evaluated. Results showed observable trade-offs in image quality at highest accelerations using single echo trains to scan the whole brain and good quality images using two or three echo trains.
