Computed Tomography (CT or CAT) is a noninvasive, painless imaging exam used to help diagnose and treat an array of medical conditions. CT scans are similar to conventional x-rays, but provide better clarity of internal organs, bone, soft tissue and blood vessels. Numerous x-ray beams and a set of electronic x-ray detectors rotate around you, measuring the amount of radiation being absorbed throughout your body. At the same time, the examination table is moving through the scanner, so the x-ray beam follows a spiral path. A special computer program processes this series of pictures, or “slices”, to create two-dimensional cross-sectional images which are then displayed on a monitor. Enhancements in detector technology allow modern CT scanners to obtain multiple slices in a single rotation. These scanners are called “multi slice CT” enabling multiple, thinner slices to be acquired in a shorter period of time, resulting in more detail and additional view capability.
For some CT exams, a contrast material is used which can be swallowed, injected intravenously, or administered by enema to enhance the image of the area being studied.
Teton Radiology’s 64-slice CT scanner and 3D workstation offer physicians a better look at internal organs for a more accurate diagnosis. High resolution images with a low x-ray dose are just what the doctor ordered.
