In this study, we simulate the effects of motion in MR Fingerprinting. We established that motion related artifacts are sensitive to the time at which motion occurs in the scan, and that T1 maps are more sensitive to the position of the subject near the beginning of the scan, likely due to T1 sensitivity from the initial inversion pulse.
