High definition fiber tracking
High definition fiber tracking (HDFT) is a medical imaging technique where data from MRI scanners is processed through computer algorithms to reveal the detailed wiring of the brain and to pinpoint fiber tracts. Each tract contains millions of neuronal connections. HDFT is based on data from 257 directions. The technique makes it possible to virtually dissect 40 major fiber tracts in the brain. The HDFT scan is consistent with brain anatomy unlike DTI. Thus, the use of HDFT is essential in pinpointing damaged neural connections.
- Diffusion MRI (DTI), uses the magnetic properties of water
- Functional magnetic resonance imaging (fMRI), measures blood flow to infer neural activity
