 There is overall relative increased mean transit time diffusely throughout the left ACA and anterior MCA territories. There is slightly increased left cerebral blood volume on relative blood volume maps in this same region indicating compensatory relatively increased blood volume, except for the left inferior parietal lobule area which was previously infarcted. Finally there is a overall relative decreased cerebral blood flow involving the left ACA and MCA territories.Comparing the area of restricted diffusion seen on the MRI, constellation of MR perfusion findings are suggesting left ACA and MCA territorial hypoperfusion with incomplete compensatory status.
Findings of diffusion-perfusion mismatch are seen on the left ACA and MCA territories. Specifically, the left ACA and MCA territories show relatively decreased perfusion with incomplete compensatory increase of relative blood volume.Findings were discussed with Dr. Satzer of neurosurgery at pager 2194 by Dr. Veronesi of neuroradiology.
