Prior to the introduction of computed tomography (CT) in 1974, neuroradiologic examinations of the brain consisted primarily of plain films of the skull, cerebral arteriography, pneumoencephalography, and conventional nuclear medicine studies. Unfortunately, these techniques, for the most part, provided only indirect information about suspected intracranial processes, were insensitive in detecting subtle or early brain lesions, or were potentially harmful to the patient. Computed tomography revolutionized the radiologic workup of central nervous system (CNS) abnormalities because for the first time normal and abnormal structures could be directly visualized with minimal risk to the patient.
