Segmentation of multiple sclerosis lesions in intensity corrected multispectral MRI

TL;DR: To segment brain tissues in magnetic resonance images of the brain, the authors have implemented a stochastic relaxation method which utilizes partial volume analysis for every brain voxel, and operates on fully three-dimensional (3-D) data.

U I in Intensity Corrected Multispectral MRI

TL;DR: To improve lesion segmentation of multispectral MRI scans of multiple sclerosis patients, the method of stochastic relaxation is extended by both pre- and post-processing the MR images and results compare favorably to manual segmentations of the same scans obtained independently by radiology health professionals.
