what is an CT Scan? the scan itself how to prepare for CT are there any risks? CT staff FAQs

Q. Can I bring a relative or friend into the room with me?
A. No. Only the patient can be exposed to X-rays. This is for radiation protection purposes. Of course, a relative or friend can be present just outside the scanning room.

Q. Will the CT scan hurt?
A. No. The scan itself isn't painful.

Q. Will I feel claustrophobic?
A. Most people suffering from claustrophobia are comfortable with CT scans. The scanner opening is large, allowing lots of space around you.

Q. Can I move during the scan?
A. You should stay as still as possible during the scan. For some scans of the chest and abdomen you will be asked to hold your breath for up to 6-7 seconds. This eliminates blurring on the CT images caused by breathing or other patient movement.

Some patients cannot hold their breath and/or may find it uncomfortable or difficult to lie still. If you have any pain, discomfort or breathing problems that may lead to difficulties during the scan then let the radiographer know before the scan begins.

Q. Will I have an injection?
A. Not everyone needs an injection for CT imaging. However, in most cases an injection of a liquid called 'contrast medium', containing iodine, is injected into a vein in your arm or hand.

It is used to make specific organs, blood vessels or tissue types 'stand out' more clearly on the CT images. The radiologist, a medical doctor, decides when the injection is necessary.

Some patients, particularly those having chemotherapy treatment, may have veins that are difficult to inject. If this is the case for you then please let the staff know as soon as you arrive at the Scanner Centre. Heat pads are available to make the injection easier.

Q. Are there any side effects from the injection?
A. Common side effects include a warm 'flushed' feeling during the injection of the contrast medium and a 'metallic' taste in the mouth, which usually lasts for a few seconds

You should inform the radiographer if you have a history of asthma, allergy, diabetes, heart problems or kidney problems. These conditions may indicate a higher risk of contrast medium reactions.

Q. Is CT scanning safe?
A. Yes, CT is considered a safe examination. In general, the diagnostic benefit of a CT scan outweighs the risks of X-ray radiation exposure.

Q. Can I have a CT scan if I am pregnant?
A. All women of childbearing age should only have a CT scan of the abdomen and pelvis during the first 10 days of their menstrual cycle. Otherwise, pregnant women should not have a CT scan or any other X-ray examination, especially during the first trimester (first 3 months of pregnancy). Sometimes a CT scan is absolutely necessary and then we take additional protective measures. Please inform the radiographer if you are, or think you may be, pregnant.

Q. What happens after the scan?
A. After the scan the CT staff will make sure you are comfortable and ready to go home. There are no adverse side effects to the scan so you can eat, drink and drive normally.

Q. How do I get the examination results?
A. The radiographer does not give you the scan report. The scan is interpreted by the radiologist after the examination. This takes quite some time, as there are often a large number of images to review. A report will be sent within a few days to the doctor who referred you for the scan. You must see your referring doctor to obtain the result.

Q. What if I have any other questions after reading the instructions in the appointment letter?
A. Please feel free to phone us on 01923 844915 between the hours of 9am to 5pm, Monday to Friday. If you call outside these times there is an answer phone service. Please leave a message and we will contact you as soon as possible.
