Neurological applications of computed tomography.
Prior to the development of computed tomography, radiographic visualization of the brain and spinal cord relied on the indirect imaging methods of angiography, pneumography, and myelography. Although those invasive techniques still play an important diagnostic role, computed tomography has largely replaced them as the main imaging modality of the brain. Its rapid noninvasive nature heralds a major advance in clinical neurological diagnosis.
