Abstract
SUMMARY: 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.
