  • Method of predicting stroke evolution utilising mri
    Publication number: 20040106864
    Abstract: A method predicting stroke evolution uses magnetic resonance diffusion and perfusion images obtained shortly after the onset of stroke symptoms to automatically estimate the eventual volume of dead cerebral tissue resulting from the stroke. The diffusion and perfusion images are processed to extract region(s) of interest presenting tissue at risk of infarction. A midplane algorithm is also used to calculate ratio and diffusion and perfusion measures for modelling infarct evolution. A parametric normal classifier algorithm is used to predict infarct growth using the calculated measures.
