Description

Andersson and Sotiropoulos described in 2016 a method to clean up diffusion MRI scans. Diffusion imaging tracks water movement to map brain wiring, but scans are distorted by eddy currents from the scanner and by subject movement. These off-resonance effects can ruin fine detail if left uncorrected.

Their approach estimates and corrects both distortions after the scan, in one integrated model. A susceptibility field map, if available, is folded into the same calculations. Cleaner images mean tract maps and measures of white matter are more trustworthy. Brain studies of development, aging, and disease depend on that accuracy.
