the volumetric navigator (vNav) prospective motion correction system significantly reduces the motion-induced bias and variance in morphometry. * tisdall@nmr.mgh.harvard.edu, A.  ...  Recent work has demonstrated that subject motion produces systematic biases in the metrics computed by widely used morphometry software packages, even when the motion is too small to produce noticeable  ...  The volumetric navigator (vNavs) system allows the scanner to track the subject's head during the scan and prospectively correct for subject motion (Tisdall et al., 2012 , Hess et al. (2011 ). vNavs are  ...

Head motion during MRI acquisition reduces gray matter volume and thickness estimates

Martin Reuter, M. Dylan Tisdall, Abid Qureshi, Randy L. Buckner, André J.W. van der Kouwe, Bruce Fischl
2015 NeuroImage  
We show that volume and thickness estimates of the cortical gray matter are biased by head motion with an average apparent volume loss of roughly 0.7%/mm/min of subject motion.  ...  A systematic effect can be problematic since factors of interest like age, disease, and treatment are often correlated with both a structural change and the amount of head motion in the scanner, confounding  ...  BF's interests were reviewed and are managed by Massachusetts General Hospital and Partners HealthCare in accordance with their conflict of interest policies.  ...
