FIG 4. Case 9: 82-year-old woman with subacute IVH and intraparenchymal hemorrhage who had imaging 5 days after ictus. MR images and a CT scan were obtained 2 hours apart. The CT scan shows the IVH better than the MR images do.

A and B, Layered IVH is isointense with gray matter on all three MR sequences and is thus inconspicuous on the FLAIR image (6700/150/2, TI = 2200) (A), the T2-weighted image (2000/120/2) (B), and the T1-weighted image (450/20/2) (not shown).

C, Noncontrast CT scan readily shows the hyperdense intraparenchymal hemorrhage and hyperdense ipsilateral layered IVH. The IVH is more conspicuous on the CT scans than on the MR images.
