Correct preparation for the examination
• Brain, neck, thorax and abdomen: Do not eat 3 hours before the examination.
• Cardiac CT: according to protocol.
• Virtual colonoscopy CT: according to protocol.
• CT ENTEROGRAPHY: according to protocol.
• Other: no preparation.
• If it is necessary to inject a contrast medium, to help with diagnosis, please notify us of your history of allergies.
A questionnaire will be provided for you to complete upon your arrival.
You will be lying on a table (most often on your back), which moves through an open ring. This is the centre of a source of X-rays and detectors that rotate around the patient, to measure the radiation passing through them at every moment.
The medical team does not remain in the room but communicates through a microphone. It is important that you remain as still as possible during this examination which can last for approximately 5 to 20 minutes for the longest exams.
In some cases, the intravenous injection of an iodine-based contrast medium will be necessary.
It is also possible that you may be asked, in order to help with the diagnosis, to drink a contrast medium or to accept the introduction of air or contrast into the colon.
The X-rays used are generally to be avoided by pregnant women. Depending on the pathology involved, certain indications are however justified.
It is therefore imperative to report if you are pregnant or could be pregnant.
The administration of the venous contrast, may cause some hot flushes or a strange taste in the mouth. The injected iodine may be the cause of allergies thus it is imperative for patients to have previously reported their history.
It is essential to inform the medical staff of any kidney failure or diabetes problems so that we can take all possible precautions.
At the end of the examination, our doctor will be available for a comment that shall not be of diagnostic value. This will be evaluated by the doctor in charge of your records in our centre then transmitted to your referring doctor. You should also expect a slight wait so that you can leave with your images and a DVD of your examination (reconstruction and recording time).
