To diagnose kidney or gall stones
To diagnose a slipped or bulging vertebral disc
To assess lesions and cysts
To diagnose cancer
…and many more
CT images are taken by specialist staff called Radiographers. These images are then interpreted and reported upon by specialist doctors called Radiologists.
For the examination, your Radiographer may ask you to remove any clothing that might obstruct the accuracy of your images and wear a provided gown where necessary. You will then be asked to lie on the CT table which slides through the circular CT machine. When this is happening you will be asked to keep very still and hold your breath for a few seconds. Whilst you are doing this, the CT machine will be taking images. Once the Radiographer is satisfied that the images are accurate the procedure is finished. Capturing the images takes only a few seconds but the processing of the films may take several minutes. There is no pain or discomfort caused by the CT scan and you will have your films within an hour from walking into the building in most cases. Remember to take your films to your next doctor’s appointment.
As CT’s are a type of x-ray, you should be careful not to have too many as excessive exposure caused by too many CT scans in a short time can be harmful to the body. To avoid over exposure to CT scan radiation, radiographers who work in x-rays and CT scans are required to stand behind a protective glass shield when your pictures are being taken.
Most CT scans require preparation in order to ensure that the images are accurate. These will typically involve fasting and sometimes you will be asked to drink a contrast drink prior to your appointment.
Contrast is usually an iodine or barium based liquid. As such there is always a small chance that it may cause an allergic reaction. Before you are given the contrast you will be asked if you are allergic to iodine, shellfish or seafood. This is because shellfish and seafood has traces of iodine in them naturally and an allergy to them may indicate an allergy to iodine. In such cases, alternative contrasts can be considered.
Yes. Although there is usually little or no waiting times for a CT scan, appointments are essential as there is often some preparation required
