Multiple Sclerosis (MS) is an autoimmune disease; disease can be measured on MRI by the appearance or enlargement of lesions. PVS measurements on MRI may represent a more predictive biomarker of disease. Because manual measurement of PVSs is time intensive, our collaborators developed a tool to automatically segment PVSs. Here, we investigated the utility of the automatic segmentations. We correlated the automated PVS counts with manual segmentations (0.66), as well as the PVS areas (0.55). Differences between healthy control and MS groups in this preliminary analysis were not statistically significant. Future work will expand from 45 to 300 patients.
