Structural integrity of white matter tracts as a predictor of acute ischemic stroke outcome

Clinical assessment scores in acute ischemic stroke are only moderately correlated with lesion volume since lesion location is an important confounding factor. Many studies have investigated grey matter indicators of stroke severity but the understanding of white matter tract involvement is limited in the early phase after stroke. Carmen Lahiff-Jenkins, Managing Editor for the International Journal of Stroke spoke to Dr Deepthi Rajashekar from the Biomedical Engineering Graduate Program, Department of Radiology, University of Calgary and Professor Michael Hill Cumming School of Medicine, University of Calgary and Foothills Medical Centre. Both are authors of the manuscript Structural integrity of white matter tracts as a predictor of acute ischemic stroke outcome published recently in IJS. This study aimed to measure and model the involvement of WM tracts with respect to 24-hours post-stroke National Institutes of Health Stroke Scale (NIHSS) and have found that white matter tract integrity and lesion load are important predictors for clinical outcomes after acute ischemic stroke as measured by the NIHSS and should be integrated for predictive modelling.
