Diffusion MRI processing in the HEALthy Brain and Child Development study: Innovations and applications
The landmark ongoing HEALthy Brain and Child Development (HBCD) study will longitudinally chart brain development in a large sample (projected n = 7200) of infants through age 10 years with multimodal neuroimaging that includes an advanced diffusion MRI (dMRI) acquisition. Here, we detail advances in dMRI image processing developed for HBCD, incorporated into the widely used QSIPrep pipeline. Major changes to preprocessing include improvements in infant brain extraction, distortion correction,...

Highly replicable multisite patterns of adolescent white matter maturation
Adolescent brain development is difficult to study at scale because diffusion MRI (dMRI) measures are sensitive to technical variability across scanning environments. The Adolescent Brain Cognitive Development (ABCD) study is the largest US-based longitudinal neuroimaging study of adolescent brain maturation. We present ABCD-Brain Imaging Data Structure (BIDS) Community Collection (ABCC) release 3.1.0, a curated resource of more than 24,000 fully processed human ABCD dMRI datasets from...

Takeaway #4: Some acquisitions can do more than one job.
dMRI, MP2RAGE, and T1w/T2w provide myelin-sensitive information while also supporting tractography, quantitative or anatomical imaging, and standard structural workflows—an important advantage when scan time is limited.

First question: how well do these metrics differentiate gray and white matter?
The answer: a lot!
MP2RAGE R1 showed the strongest differentiation, followed by several dMRI, T1w/T2w, and ihMT measures. QSM measures showed much weaker and more heterogeneous differences.

Next: test–retest reliability.
dMRI-derived metrics were consistently among the most reliable measures, with many median ICCs approaching or exceeding 0.9.
MP2RAGE R1 and T1w/T2w also performed well.
QSM, R2*, and ihMT (especially in gray matter) were more variable.

2/4 dMRI will never directly “image inflammation”. It measures water displacement. But for >10 years I’ve believed we can capture transient changes in extracellular space/tissue microstructure that may tell us something about disease state, risk & treatment response in mental illness and neurology.
