CT scanning is a diagnostic imaging technique using X-rays to build a 2D or 3D image of an area of interest on your body.
CT scans can be used for a variety of reasons, including but not limited to:
A CT scanner is shaped like a large standing circle which holds the X-ray transmitter and detector. It has an opening in its centre through which a table slides. During the procedure, you will lie on the table which will then move into the scanner. The X-ray tubes will revolve around the part of your body to be imaged, the detectors will receive the signals and then transmit them to a computer which will process and visualise the final image.
As CT scans use X-rays there is some exposure to radiation. This is not harmful, and any risk associated are extremely small. Sometimes, a contrast material is injected before scanning to get better pictures, which may cause an allergic reaction in some patients. All in all, the benefits of the imaging far outweigh the small risks associated with it.
