What Is A CT Scan?
A computed tomography scan (usually abbreviated to CT scan; formerly called computed axial tomography scan or CAT scan) is a medical imaging technique used to obtain detailed internal images of the body. The personnel that perform CT scans are called radiographers or radiology technologists.
CT scanners use a rotating X-ray tube and a row of detectors placed in a gantry to measure X-ray attenuations by different tissues inside the body. The multiple X-ray measurements taken from different angles are then processed on a computer using tomographic reconstruction algorithms to produce tomographic(cross-sectional) images (virtual “slices”) of a body. CT scan can be used in patients with metallic implants or pacemakers, for whom magnetic resonance imaging (MRI) is contraindicated.
Since its development in the 1970s, CT scanning has proven to be a versatile imaging technique. While CT is most prominently used in medical diagnosis, it can also be used to form images of non-living objects. The 1979 Nobel Prize in Physiology or Medicine was awarded jointly to South African-American physicist Allan M. Cormack and British electrical engineer Godfrey N. Hounsfield “for the development of computer-assisted tomography”
How Much Is A Ct Scan?
CT scans can have a cost range from $270 all the way up to over $5,000 for the highest end in general. Facility, location, and payment methods, along with your insurance provider, determine the cost.

The cash-paying patients can pay more for these scans as long as the doctor correctly diagnoses it and appropriate referrals come from medical experts. Generally, most Medical Aids cover all costs at a given time.
How Much Does An Mri Cost South Africa?
Among all nine countries surveyed by the International Federation of Health Plans, the most expensive method of magnetic resonance imaging (MRI) scan is in South Africa’s private health sector. An x-ray procedure costs generally about R8 800 – R1 200 higher in Switzerland, which doubles that in Chile on average.

Medical Use Of CT Scans
Since its introduction in the 1970s,CT has become an important tool in medical imaging to supplement conventional X-ray imaging and medical ultrasonography. It has more recently been used for preventive medicine or screening for disease, for example, CT colonography for people with a high risk of colon cancer, or full-motion heart scans for people with a high risk of heart disease. Several institutions offer full-body scans for the general population although this practice goes against the advice and official position of many professional organizations in the field primarily due to the radiation dose applied.
The use of CT scans has increased dramatically over the last two decades in many countries.An estimated 72 million scans were performed in the United States in 2007 and more than 80 million in 2015
