To aim for reliable parametric mapping to motion artifact, prospective motion correction was integrated to a multi-parametric technique, 3D QALAS. 2D Spiral navigators were inserted into wait times in the QALAS without impacting scan time for motion tracking and correction. The effectiveness of prospective motion correction was demonstrated. The proposed technique is expected to yield prospectively motion corrected 3D brain volumetric images of multiple contrasts and quantitative mappings.
