After a CT scan (computed tomography), it’s normal to have questions: when will I receive my results? Are there any side effects? Do I need to take any special precautions?

This article helps you better understand what happens after a CT scan, especially if your exam was performed at a medical imaging clinic in Montreal.

What happens immediately after a CT scan?

In most cases, once the exam is over:

  • you can get up and leave the exam room

  • the catheter (if one was used) is removed

  • no prolonged monitoring is required

You can generally return to your normal activities after your appointment.

Should you take any precautions after the exam?

Some recommendations may be suggested, especially if a contrast agent was used.

Hydration

It is often recommended that you drink water in the hours following the exam. This can help your kidneys eliminate the contrast agent more quickly.

Possible side effects

In most cases, no particular side effects are felt after a CT scan. However, some reactions may occur, especially when a contrast agent is used:

  • mild fatigue

  • a temporary sensation related to the contrast agent

  • more rarely, an allergic reaction

If you experience unusual symptoms after your exam, it is recommended that you consult a healthcare professional.

When and how do you receive CT scan results?

After your exam, the images are analyzed by a radiologist and a report is prepared. The results are then sent to the referring physician.

How long does it take to get the results?

The timeline can vary depending on the type of exam, the clinical context, and the urgency of the situation. In general, results are sent within a few days. For urgent cases, the turnaround time may be shorter.

Who explains the results to you?

Usually, the doctor who ordered the exam receives the radiologist’s report, interprets the results in the context of your medical situation, and explains the next steps to you.

Should you plan for follow-up after a CT scan?

Depending on the results, your doctor may recommend additional tests, propose a treatment, or request medical follow-up. In some cases, no particular follow-up is needed.

  • You can generally return to your normal activities
