MRI
- Often shows high signal intensity in the caudate nucleus and putamen bilaterally on T2-weighted images.
- Diffusion Weighted Imaging (DWI) images are the most sensitive. In about 24% of cases DWI shows only cortical hyperintensity; in 68%, cortical and subcortical abnormalities; and in 5%, only subcortical anomalies.[1]
- The involvement of the thalamus can be found in sCJD, even is stronger and constant in vCJD.[2]
- An abnormal signal in the posterior thalami on T2- and diffusion-weighted images and fluid-attenuated inversion recovery sequences on brain magnetic resonance imaging (MRI); in the appropriate clinical context, this signal is highly specific for vCJD. (Source: CDC)
