75-year-old male with history of cortical ribboning. Evaluate for etiology of altered mental status - want to get ONLY DWI and DTI sequence. Again seen is relatively symmetric cortically based mild restricted diffusion involving the bilateral parietal and occipital lobes and to a lesser degree the frontal and temporal lobes. The intensity of the diffusion restriction appears to have diminished on comparison with the prior examination. No new areas of restricted diffusion are seen.
Areas of bilateral cortical restricted diffusion, primarily in the parietal and occipital lobes, are again demonstrated. There has been no significant change in the geographic distribution of these lesions, though the intensity of the diffusion restriction has diminished.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
