In contrast to motion artifacts in conventional MRI, which can often be identified by visual inspection, the effect can be more subtle in quantitative MRI (qMRI) methods such as Magnetic Resonance Fingerprinting (MRF). Subject motion during qMRI scans can lead to altered parameter maps without affecting their morphologic appearance which limits the user’s possibility to assess the scan quality. One way to mitigate motion artifacts is to track the subject’s movement and prospectively correct for the motion. Here, we present results of applying prospective motion correction using an in-bore camera system for MRF.
