Do Early MRI Signals Predict Lesion Size in a Neonatal Stroke Rat Model?
Résumé
In this study, we compared lesion size by using VADC and VT2 at 0, 2, 5, 24, and 48 hours and histologic lesions at 48 hours in a P7 rat stroke model. The best correlation between VHISTO and VADC was at H0, and between VHISTO and VT2, at H2-H5. Early MR imaging signals allowed excluding “no-lesion” and “no-reflow” animals to help standardize this neonatal stroke model and predict lesion size.
