Computed Tomography (CT)

Computed Tomography (CT) is the mainstays modality of neuroimaging. An X-ray tube within a circular gantry revolves around the patient, and radiation detectors on the opposite side of the gantry detect the X-ray beam and send the information to sophisticated computers that generate a series of cross-sectional images. It is now readily available in most centres and is an excellent initial examination for brain abnormalities.
