What questions should I ask if I'm concerned about getting a CT scan?

ANSWER

Before you have any imaging test, ask your doctor these questions:

  • Why do I need this scan?
  • How will it affect my treatment?
  • What are the risks?
  • Could you diagnose me with a test that doesn’t use radiation, like an MRI or an ultrasound?
  • How will you protect the rest of my body during the CT scan?
