==== CT ====

Typically a region of hyperdensity is demonstrated centered on the [[basal ganglia]] or [[thalamus]]. Not infrequently there may be an extension into the [[ventricle]]s, with occasionally the [[parenchyma]]l component being very small or inapparent.

If there is no intraventricular extension, the volume of the hemorrhage may be estimated by [[ABC/2]] and related formulas, which may have neurosurgical and prognostic implications.

There are many predictors of [[hematoma expansion]] potentially evident on CT
see [[Spontaneous intracerebral hemorrhage expansion]]

==== MRI ====
The appearance of hemorrhage on MRI varies with time and to some degree the size of the hematoma (see aging blood on MRI).
