Diffusion imaging for neuronal fiber track display accelerated with simultaneous image acquisition. The 3D images show neuronal axon fiber tracks in the human brain, in vivo, using simultaneous image refocused (SIR) EPI with either 2 or 3 images per echo train. Compared to EPI (left) the full 3D data set was acquired 2-3 times faster with SIR-2 EPI (center) and SIR-3 EPI (right) with acquisition times shown. The fibertrack images were not exactly aligned and small differences in distortion are present. The colors designate direction of fibers in orthogonal axes. Adapted from [68].
