MR Brain WWO Neuro Protocol
Problems with patient motion?
3D imaging and compressed sense are very susceptible to patient motion. If you have exhausted the usual motion-combatting strategies (padding, medication, etc.), then switch to seqeunces less sensitive to motion including radial k-space sampling (PROPELLER, BLADE, MultiVane, StarVibe), single-shot, or just routine 2D sequences.
