Although these tools can be very useful in some situations, it is recommended that they are not used routinely or in situations in which the diagnosis is already clear. A major risk of these medical diagnostic imaging procedures is that they lead to low-dose ionizing radiation exposure. The main concern for this radiation exposure is the risk for future cancer. Children and infants are at higher risk of this compared with adults because children's tissues are still developing and are thus more sensitive to radiation and because children have a longer life span, which may allow additional time for negative health effects to happen.
