Imaging-based quantitative measures from diffusion-weighted MRI (dMRI) offer the ability to non-invasively extract microscopic information from human brain tissues.
NIH Awards $10 Million to researchers at UW-Madison and the University of Utah for landmark study on aging in autistic adults
Recent studies suggest that older adults with ASD may have shorter life expectancies and more physical and mental health difficulties than the general population. A new, landmark longitudinal study of aging and autism hopes to better understand how differences in aging may impact the health outcomes of individuals with ASD.

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.

The segmentation of small brain structures like the amygdala is quite challenging in the presence of distorted and abnormal anatomy from major brain injuries.
Pediatric Brain Care Study (Ferrazzano & Alexander)
The Pediatric Brain Care Study is recruiting typically developing children, 9-17 years old, with no history of head injury for a brain imaging research study. Those who participate will have a MRI brain scanning and …

Researchers unveil new strategy to correct for motion during MRI scans
Individuals undergoing a magnetic resonance imaging (MRI) scan often need to minimize movements for up to 10 minutes at a time to maximize scan quality. That can be challenging for many people.
