PET is combined with some current imaging techniques to produce both functional and anatomical information. One of these combined approaches involves an increase in the ionizing radiation experienced by the patient. Which hybrid technique is this?

PET/CT combines PET with computed tomography (CT). CT uses X-rays, which are ionizing radiation, so this hybrid scan adds radiation exposure beyond the PET component. PET/MRI and PET/Ultrasound do not use ionizing radiation for their imaging methods.
