THREE-DIMENSIONAL DIFFUSION WEIGHTED MAGNETIC RESONANCE IMAGING

According to a method for three-dimensional diffusion weighted magnetic resonance imaging, a diffusion gradient (13x, 13y, 13z) is applied by controlling a gradient coil arrangement (5) of an MRI system (1) and, during an acquisition period after the application of the diffusion gradient (13x, 13y, 13z), a readout gradient (15a) is applied by controlling the gradient coil arrangement (5) and MR data is acquired. For applying the readout gradient (15a), the gradient coil arrangement (5) is controlled such that the MR data is acquired at least along a trajectory segment (18a) of a three-dimensional k-space trajectory (18), wherein a k-space center is sampled by the trajectory segment (18a) multiple times during the acquisition period.
