MR imaging of cerebral hemiatrophy.

Computed tomography has been the procedure of choice in evaluation of cerebral hemiatrophy, particularly in those instances where plain radiographic studies of the skull are nondiagnostic. Our experience suggests that magnetic resonance (MR) can easily accomplish the same task. Furthermore, by virtue of its exquisite soft tissue detail, MR can afford additional clarity and information with respect to relative gray-white matter loss, subarachnoid space size, gyral deformity, as well as highlighting asymmetry of the cerebral peduncles, internal capsules and the thalami.
