Assessment of acute spontaneous intracerebral hematoma by CT perfusion imaging

A single-section deconvolution-derived computerized tomographic perfusion imaging was performed in 45 patients (22 male and 23 female; mean age=69.89±10.07 years) with acute supratentorial spontaneous intracerebral hemorrhage. Mean rCBF and rCBV were lower in the hemorrhagic core than in the perihem...

Summary:A single-section deconvolution-derived computerized tomographic perfusion imaging was performed in 45 patients (22 male and 23 female; mean age=69.89±10.07 years) with acute supratentorial spontaneous intracerebral hemorrhage. Mean rCBF and rCBV were lower in the hemorrhagic core than in the perihematomal low density area (p<0.001), and in the perihematomal low density area than in normal appearing brain parenchyma (p<0.001). Mean rMTT values were higher in perihematomal low density area than in normal appearing area (p<0.01) and in both hemorrhagic and perihematomal area than in controlateral ROI (p<0.001). There were no differences in rMTT mean values between hemorrhagic core and perihematomal area, as well as between normal appearing and controlateral areas. We found a concentric distribution of all CT perfusion parameters characterized by an improvement from the core to the periphery, with low perihematomal rCBF and rCBV values suggesting edema formation. Une coupe unique de scanner de perfusion avec déconvolution était réalisée chez 45 patients (22 hommes et 23 femmes; âge moyenne = 69,89 ± 10,07 years) présentant un hématome intracérébral aiguë sustentoriel (HIAS). Le débit sanguin cérébral (DSC) et volume sanguin cérébral (VSC) moyens est plus bas au centre qu’en périphérie de la zone d’hypodensité qui est plus bas qu’en zone isodense (p < 0,001). Les valeurs de temps de transit moyen (TTM) étaient > zones périlésionnelle > zone isodense (p < 0,001). Il n’y a pas eu de différence en TTM entre le centre et la zone périhémorragique. Nous avons trouvé une distribution centrifugecaracterisée par une amélioration des paramètres de perfusion du centre à la périphérie avec les valeurs basses de DSC VSC suggerant une formation d’édeme.
