1. A method for performing three-dimensional diffusion weighted magnetic resonance imaging (DWI), comprising:
applying a diffusion gradient by controlling a gradient coil arrangement of a magnetic resonance imaging (MRI) system; and
during an acquisition period that occurs after the application of the diffusion gradient, applying a readout gradient by controlling the gradient coil arrangement and acquiring MR data,
wherein for applying the readout gradient, the gradient coil arrangement is controlled such that the MR data is acquired along a trajectory segment of a three-dimensional k-space trajectory, and
wherein a k-space center is sampled by the trajectory segment multiple times during the acquisition period.
