Many misconceptions exist about the risks associated with radiation doses and CT scans. Experts at Mayo Clinic want patients to have the right information about radiation dose, including when to have procedures with radiation, such as a CT scan, versus when to have magnetic resonance imaging or other non-radiation tests. Since 2001, a team of diagnostic radiologists and medical physicists at Mayo Clinic have been actively developing and implementing new techniques to lower doses from CT. They have installed new CT scanners and software and implemented new scanning instructions to lower the doses for more than 100 different CT protocols. Amy Hara, M.D., a diagnostic radiologist at Mayo Clinic Arizona, says that doses have dropped more than 50 percent for several scan types. She emphasizes that their goal is to reduce the radiation dose without compromising the image quality — and advances in technology are making that possible.
