CT or CAT (Computed Axial Tomography) scans produce cross-sectional images of the body using x-rays and a computer.

A standard x-ray image or radiograph appears as if you are looking through the body. CT scanners  produce cross-sectional slices of the body, which can be reconstructed to produce 3-dimensional images.

CT uses x-rays in a rotating form.  As a patient lies in the bore of the scanner, an x-ray rotates around the patient.  This x-ray is continuously taking pictures, and each rotation produces a cross-sectional image of the body  - “a slice.”  These slices appear to open the body up.

Radiologists are able to study these slices and interpret the area of interest.  allowing the doctor to look at it from the inside.  When considered, this is revolutionary as previously doctors could have only see similar detail either through surgery or autopsy.

CT scans are frequently used in ENT, oncology and cardiology.
The key features that determine the quality of the image are the number of slices taken in one rotation, the thinness of each slice (the thinner the slice, the greater the resolution) and the speed of the rotation of the x-ray.  All else being equal, the greater each of these factors the better the image, the better the examination and the better the diagnosis.

MDI chooses scanners on these criteria, and have installed the latest 64-slice scanners in our centres.  This, together with dedicated development of new examinations such as the Cardiac CT Angiograms, has enabled us to be the company with the most number of fixed independent sites.
