Abstract
L'invention concerne l'interprétation et l'évaluation d'images de réactivité cérébrovasculaire (CVR), qui reposent sur un examen qualitatif d'anomalies possibles qui sont considérées comme des défauts d'homogénéité des cartes CVR qui semblent différer des cartes CVR d'individus sains. Un système d'imagerie, qui combine des cartes z avec un stimulus standardisé, offre une image à haute résolution indiquant la présence, la localisation et la gravité de la CVR pathologique. Le stimulus standardisé est sous la forme de pressions partielles artérielles ciblées de dioxyde de carbone, qui permettent d'évaluer la gravité et la distribution d'une anomalie ou la réduction d'une réponse vasculaire d'un sujet à un stimulus vasoactif dans au moins une région d'intérêt du cerveau du sujet. Des cartes Z sont utiles pour réduire les effets de variabilité de test-à-test, sujet-à-sujet et plate-forme-à-plate-forme en vue d'une comparaison d'images CVR.
