Technical Factors:
Using a 1.0 Tesla superconducting magnet, T₁ weighted sagittal and T₁ weighted, T₂ weighted and FLAIR axial images were obtained.

Diffusion weighted axial images were also obtained. Following intravenous administration of Gadolinium DTPA contrast, T₁ weighted axial images were obtained.

Working Diagnosis: Multiple Sclerosis

Findings:

1. On both FLAIR and T₂ weighted images, two oval HyperIntensities are noted in the PeriVentricular White Matter of the right Cerebral Hemisphere.
2. There is no evidence of abnormal enhancement associated with either of these rounded signal abnormalities.
3. Punctate, slightly less well defined HyperIntensities are noted in the left Basal Ganglia and in the White Matter adjacent to the Trigone of the Lateral Ventricle on both sides.
4. Once again, there is no evidence of contrast enhancement associated with these signal changes.
   • The larger of the lesions in the right PeriVentricular White Matter demonstrate high signal on Diffusion-weighted images, which likely relates to T₂ shine-through.

5. The Ventricles are normal in size, shape and position.
6. There is wedge-shaped abnormal signal in the left posterior Parietal Lobe, HypoIntense relative to normal Brain on T₁ weighted images, and HyperIntense on T₂ weighted images.
   • There is markedly diminished signal in this region on Diffusion-weighted images.

7. There is no evidence of mass effect or ExtraCerebral fluid collection.
