CT Scanning

CT scan stands for computerised tomography scan. The scan uses x rays and a computer to create a detailed image of the inside of the body. 

A CT scanner is a large piece of equipment that is shaped like a ring with an internal x ray scanner. As you lie down the x ray scanner moves up and down in small movements around the affected area and uses x ray beams to provide a detailed image of the area.

The images produced by a CT scan are called tomograms. They are more detailed than standard X-rays, which use a single beam of radiation, and can give views of structures inside the body including internal organs, blood vessels, bones and tumours.

CT scans are used to diagnose many health conditions including bone disease and cancer. This is often the first option prior to any surgery to ascertain the potential problem.

A CT scan is painless and usually takes between 10 and 30 minutes depending on which part of your body is being scanned.

Although x ray is being used it is important to know that the amount of radiation you are exposed to is safe and is not enough to cause any harm.

Children are generally more affected by the build up of radiation through the x ray and the CT scan is not advised for pregnant women.

Your consultant will discuss any questions or worries you may have prior to the procedure. 

This procedure will normally be covered by the medical insurance policy but patients are advised to check with the provider prior to any treatment.

If the patient is paying for their own treatment all costs will be discussed and explained prior to any treatment taking place. This will be confirmed in writing along with any surgeon fees, anaesthetist fees and hospital charges prior to admission.

However, CT scans are not recommended for pregnant women because of the risk to the unborn baby. Children are more at risk than adults from a build-up of radiation doses and should only have a CT scan if it is justified by a serious condition that puts them at a higher risk.
