Method for Operating a Magnetic Resonance Imaging Device, Magnetic Resonance Imaging Device, Computer Program and Electronically Readable Storage Medium

A magnetic resonance imaging device, comprising:

• a controller configured to:
• acquire, based on a magnetic resonance sequence, magnetic resonance diffusion data in k-space in at least one repetition for diffusion imaging in an acquisition volume of a patient, wherein the magnetic resonance sequence comprises, in each repetition:
• a diffusion preparation module comprising at least one tip-down radio frequency pulse, at least one tip-up radio frequency pulse, and at least one diffusion gradient pulse group between the tip-down radio frequency pulse and the tip-up radio frequency pulse, and a readout module;
• and
• apply the tip-down radio frequency pulse slab-selectively by using a first slab selection gradient pulse in a phase-encoding direction.

An apparatus comprising:

• one or more processors;
• and
• memory storing instructions that, when executed by the one or more processors, cause the apparatus to:
• acquire, at least in one repetition and using a magnetic resonance sequence, magnetic resonance diffusion data in k-space, wherein magnetic resonance sequence comprises, for each repetition:
• a diffusion preparation module comprising at least one tip-down radio frequency pulse, at least one tip-up radio frequency pulse, and at least one diffusion gradient pulse group between the tip-down radio frequency pulse and the tip-up radio frequency pulse;
• and
• a readout module, wherein the tip-down radio frequency pulse is slab-selective by applying a first slab selection gradient pulse in a phase-encoding direction.
