It has revolutionized the neurological diagnosis of intracranial lesions by its remarkable capacity to display slices of the brain with structures outlined on the basis of minor density changes. So widely has it now been used that a detailed recitation of its applications is scarcely necessary. The identification and localization of masses, often with additional evidence as to their nature, the demonstration and differentiation of infarcts and hemorrhages, and the disclosure of hydrocephalus and of atrophy constitute its principal applications.
