Validation of IVH by means of ultrasound and tissue histology. (A-C) show representative ultrasound imaging results obtained 24 h following experiments. The images correspond to representative IVH-, IVH+, and sham animals. In these cross-sectional images, the yellow ovals indicate the ventricular region. An example of increased echogenicity in the lateral ventricles can be seen within the yellow oval in (B) (D-F) show representative images of 18-μm-thick H&E stained coronal brain slices from representative IVH-, IVH+, and sham animals, in sequence. Extravasated erythrocytes within the ventricular lumen can be seen in (E).
