CT brain hemorrhage
The basic principles of the CT brain examination, focused on intracerebral hemorrhage.
Normal Anatomy
Brain parenchyma
The brain surface consists of gyri (ridges) and sulci (grooves). In brain edema, the sulci will be compressed, as opposed to atrophy (as in Alzheimer's disease); here the sulci will expand as a result of tissue loss.
The gray matter is at the outside of the brain parenchyma. Gray matter is somewhat denser on CT than white matter. This is because white matter (as opposed to gray matter) contains the fatty substance myelin (fig. 2/3).
