Overview

• What problem does the pipeline solve, and who is the targeted user?
  • The pipeline attempts to solve the problem of segmenting white matter lusions in lupus. The capability is aimed at clinical researchers.

• How does the pipeline compare to state of the art
  • The state of the art is a work in progress in N-SLE. There are many approaches that attempt to solve lesion classification in Multiple Sclerosis. Some of these approaches are automated or semi-automated; however, all automatic approaches suffer a lack of a gold standard. It is difficult for humans manual raters to agree on fuzzy boundaries across different image constrasts (e.g., T1, T2, FLAIR).

A good example of the lack of a pipeline was the approach taken at the 2008 MICCAI Conference MS Lesion Segmentation Challenge this past May in the form of a grant challenge in segmentation. Several groups, including this DBP, competed by first being providing training data-sets with two manual labellings, approaches were judged on an application set naive to each classification approach.
