Single-shot diffusion-weighted MRI of the brainstem is
hampered by B0 off-resonance distortions, a problem that
is emphasized at high field strength (7T). To address
this problem, we implemented a reduced FOV approach by
spin-echo selection using second-order shim fields for
multi-slice imaging. The method allowed for effective
FOV reduction and thereby for robust and SNR efficient
diffusion imaging of the brain stem at high field
strength.
