Functional MRI scans can measure brain activity by detecting changes in blood flow, while structural scans take snapshots of the shape of different brain regions.

Tensor-based morphometry (TBM) analysis of T1-weighted MRI scans shows a comparison of brain volumes in participants with opioid use disorder (OUD) and healthy control participants.

Conventional MRI provides high-resolution, detailed imaging of brain structures. Functional MRI maps brain activity by detecting changes in blood flow and blood oxygenation level, which are ...

For decades, MRI (magnetic resonance imaging) has been a powerful way to see inside the human brain. A specialized form, diffusion-weighted MRI (dMRI), can measure tissue properties of fiber pathways ...

For the study, researchers analyzed data on nearly 15,900 weed users participating in the U.K. Biobank research project for whom genetic profiling and MRI brain scans were available.

In subjects with multiple sclerosis, the technique detected molecular changes associated with neuroinflammatory response and reduced neuronal activity up to 70 days before changes become visible ...

New technology combining high-speed MRI with machine learning methods for data processing found metabolic changes in oligodendroglioma brain tumors. Clinical MRI, in the left two columns, could ...
