What is a CT scan of the head?
CT scan of the head is a CT scan of the brain and the skull bones. A CT scan is an imaging modality which uses special X-ray equipment to produce multiple pictures of the inside of the body which are then joined together by a computer to produce cross-sectional views of the area being studied, in this instance, the brain. The images are then examined on a computer monitor, or printed. The CT scanner is a large machine with a tunnel, in the centre. A moveable table slides into and out of this tunnel. In the centre of the machine, the X-ray tube and electronic X-ray detectors are located opposite each other on a ring which rotates around you, measuring the amount of radiation being absorbed throughout your body. A special computer programme processes this information to create two-dimensional cross-sectional slices of your body, which are then displayed on a monitor. Common uses Any instance where injury to the brain is suspected by your doctor, especially after motor vehicle accidents,
