WebA hyperintensity or T2 hyperintensity is an area of high intensity on types of magnetic resonance imaging (MRI) scans of the brain of a human or of another mammal that reflect lesions produced largely by demyelination … WebObjective: Hypodensities on computed tomographic (CT) brain scans are thought to take at least 6 hours to become apparent after blunt head trauma. This finding, in conjunction with the later evolution of the hypodensities, is used in timing the injury in children with suspected non-accidental brain injury, in whom the history may be inaccurate.
