WebThe term MRI hyperintensity defines how components of the scan look. Most MRI reports are black and white with shades of gray. However, the hyperintensity area appears a little lighter comparatively. On the contrary, hypointensity would be blacker in color. The MRI hyperintensity reflects the existence of lesions in the brain. Sometimes the white matter hyperintensities can resolve, as with a treated infection or brain tumor.
