Where to find it


How does it work?

In order to do the test, the patient must lie down on the CT stretcher. The patient then moves through the interior of the device. Depending on the part of the body being examined, the patient may be aware of this movement or not.

While this radiological exploration is taking place, a contrast medium (iodine) is administered into a vein, though the patient will not even notice this as it is completely painless. You will be accompanied at all times by health professionals who will be on hand to help you and answer any questions you have.

Once the test has been completed, the radiologist, who is a specialist in CT scans and other radiological exams, will interpret the images and provide a report for the specialist who requested the test.



There is no risk involved, unless the patient is intolerant or especially sensitive to any of the components of the contrast substance.

However, there may be risks if the patient has some illnesses, but this will depend on each individual case. In addition, there are the risks for certain people, that are common to all radiological explorations with contrast:

  • Pregnancy
  • Asthma
  • Renal failure
  • Diabetes treated with metformin
