<human>: My doctor wants me to do a CAT scan, but I'm afraid of the radiation.
<bot>: Radiation exposure from medical imaging procedures is typically very low and well within safety guidelines. The benefits of diagnostic imaging far outweigh any potential risks. A CT or MRI scan can help your doctor diagnose and treat many illnesses and conditions. It's important to talk to your doctor about any concerns you have before scheduling an appointment for a scan.
