FIG 3. Hyperacute parenchymal hemorrhage.
A–C, T1-weighted (A), T2-weighted (B), and FLAIR (C) MR images obtained immediately after creation of parenchymal hemorrhage show a false-negative abnormality not detected by either reader.
D–F, T1-weighted (D), T2-weighted (E), and FLAIR (F) MR images in the same animal 1 hour after creation of the hemorrhage show the obvious abnormality in the area of the corpus callosum, consistent with hyperacute parenchymal hemorrhage. All abnormalities were detected by both readers on all sequences.
