Brain Lesion Analysis in Neuropsychiatric Systemic Lupus Erythematosus

Lesion volumes in yellow with ventricles and brain slice

Objective

This page describes the technology roadmap for lesion analysis in the NA-MIC Kit. Our objective is to create an end-to-end application allowing individual analysis of white matter lesions. This workflow applied to lupus patients is one of goals of the MIND DBP. The basic components necessary for this project are:

• Registration: co-registration of T1-weighted, T2-weighted, and FLAIR images
• Tissue segmentation: Should be multi-modality, correcting for intensity inhomogeneity and work on non-skull-stripped data.
• Lesion Localization: Each unique lesion should be detected and anatomical location summarized
• Lesion Load Measurement: Measure volume of each lesion, summarize lesion load by regions
• Time Series Analysis of white matter lesions: Compare lesions between multiple scans taken over time.
• Multi-scale Analysis of white matter lesions: Combine DTI, anatomical, and functional scans when analyzing lupus subjects.
• Tutorial: Documentation will be written for a tutorial and sample data sets will be provided

Roadmap

We obtained gray matter, white matter, CSF, and lesion maps for each subject based on T1-weighted, T2-weighted, and FLAIR images. Ultimately, the NA-MIC Kit will provide a workflow for individual and group analysis of lesions. It will be implemented as a set of Slicer3 modules that can be used interactively within the Slicer3 application as well as in batch on a computing cluster using BatchMake.

A. FLAIR with predicted probability of being lesion, B. FLAIR with manual segmentation, C. FLAIR with predicted probability after thresholding

White Matter Lesion Track Disruption

Compare Layout overview with baseline FLAIR image on top and followup FLAIR on bottom. Each image is overlaid with that time point's predicted lesion segmentation.

Compare Layout zoomed in. Baseline FLAIR on top and followup on bottom. Images overlaid with a label map that represents changes in lesion. Yellow represents lesion that's unchanged between baseline and followup, red represents new lesion in the followup, and blue represents lesion present at baseline that is no longer present at followup.

Zoomed detail.
