Imaging exams without radiation

Ultrasound imaging and magnetic resonance imaging (MRI) do not use radiation.

What are the effects of radiation?

Large doses of radiation from some procedures may cause temporary skin burns. However, a greater concern is that radiation may cause cancer. There is no conclusive evidence that radiation causes cancer, but large population studies have shown a slight increase in cancer even from small amounts of radiation.

Is the benefit worth the small risk?

To determine if the benefit is worth the risk, there are some questions you should ask your doctor, including:

• Is the imaging test medically necessary?
  • If the answer is yes, then the benefit will most certainly outweigh the risk.
• Can previous tests substitute for this exam?
  • If your child has had other exams that your doctor is not aware of, make sure your doctor receives copies of those exams. You may be able to avoid repeating exams your child has already undergone.
• Are there alternative exams that do not require radiation?
  • Ask your doctor if ultrasound or MRI can be substituted.
• Is the facility familiar with imaging children?
  • Children should have examinations properly tailored for their size.
