Magnetic resonance imaging, brain, functional MRI; including test selection and administration of repetitive body part movement and/or visual stimulation, not requiring physician or other qualified health care professional administration

AI EXPLANATION: A functional brain MRI, or fMRI, is an imaging scan that maps brain activity by measuring blood flow changes while you perform simple tasks. During the exam, a specialized technologist guides you through actions such as tapping your fingers, looking at visual patterns, or listening to sounds. This helps doctors see which areas of the brain handle critical functions like movement, vision, or speech.
