Computer Aided Diagnosis in Stroke

Stroke is the second leading cause of disability worldwide. In order to minimize disability, the goal of stroke treatment is to preserve tissue in the area where blood supply is decreased but sufficient to stave off cell death. Thrombectomy has been shown to offer fast and efficient reperfusion with high recanalization rates. However, due to the inherent risks of thrombectomy, indications including evidence of good collateral circulation should be present. Currently, methods for evaluating collateral circulation are limited. We are working on developing automated techniques to compute a collateral circulation score based on differences seen in mean intensities between left and right cerebral hemispheres in 4D angiography images.
