Scan (tomodensitometry)


This examination uses X-rays to obtain images of sections of organs examined in order to study their shape, size and density.
In the scanner, which is shaped like a short tunnel, the X-ray source moves around the part of the body to be examined when the table on which the patient is lying slides past.

Details of examination:



For some scans, an intravenous injection of an iodised contrast product opaque to X-rays sometimes has to be given. In this case, the patient must be given nil by mouth (nothing to eat, drink or smoke) for three hours before the examination.
For some abdominal scans, the patient must drink a product opaque to X-rays. This drink must pass through the digestive tract. This is why the appointment time can sometimes be over an hour before the examination is carried out.


A scan lasts about 10-15 minutes (including undressing time).


Injection of the contrasting product can sometimes create a sensation of heat (hot flushes) within the body, a strange taste in the mouth, and an urge to urinate.


It is important that patients with renal insufficiency or diabetes mention this when an appointment is made (especially if injection of contrasting product is involved).
Patients allergic to iodine must also mention this when an appointment is made.
