Abstract

Techniques are provided for performing three-dimensional diffusion weighted magnetic resonance imaging. A diffusion gradient is applied by controlling a gradient coil arrangement of an MRI system and, during an acquisition period after the application of the diffusion gradient, a readout gradient is applied by controlling the gradient coil arrangement and MR data is acquired. For applying the readout gradient, the gradient coil arrangement is controlled such that the MR data is acquired at least along a trajectory segment of a three-dimensional k-space trajectory, wherein a k-space center is sampled by the trajectory segment multiple times during the acquisition period.
