Andrew Alexander, PhD – Slide of the Week

Demonstration of the ability of MPnRAGE to correct for severe motion artifacts in a 7 year old girl.  Retrospective motion correction greatly reduced motion-induced blurring in both  structural T1-weighted images and quantitative T1 maps.  The correction greatly improves the reliability of brain imaging measurements in children.  The plots indicate the estimated amount of head motions that were corrected.
