Your health, safety, and imaging tests

Some imaging tests use radiation and a contrast dye. Tests that use imaging to guide a procedure may also use medicine to numb an area or help you or your child relax or sleep. Your imaging team will watch you closely to keep you or your child safe. If you have questions about safety, the test, or your health ask the imaging staff or your healthcare provider.
