Preparing for the Examination (for adults)
Possible Side Effects
Our radiologists and technologists will see to your wellbeing throughout the examination and will be available to help or answer any questions you may have.
Depending on the test prescribed by your health professional, it may be required to inject a contrast agent. We will go through a list of contrast agents with you when you book your appointment. If you think you may be allergic, please let us know.
It is also important to note that about 5% of people have a reaction to the contrast agent. If this were the case, our radiology technicians will help attenuate any symptoms. These may include the following:
- Respiratory problems
- Metallic or bitter taste in the mouth
- Hot flashes
- Facial swelling and itching
- In rare cases, the contrast agent may cause a serious allergic reaction.
Although the amount of radiation emitted during a CT scan is higher than in an X-ray, it emits a low-level ionizing radiation, which allows the use of levels considered safe for the procedure.
A medical prescription is required to perform this examination.
Please note that CT-Scan examinations are not covered by the Régie de l’Assurance Maladie du Québec (RAMQ). However, most group insurance plans cover the costs.
