Medical imaging is a technique used to create visual representations of the interior of a body for medical analysis. It is often used to diagnose and treat various medical conditions. The most common type of medical imaging is an X-ray SCAN, which uses electromagnetic radiation to create images of the inside of the body. Other types of medical imaging include ultrasound, computed tomography (CT) scans, magnetic resonance imaging (MRI), and positron emission tomography (PET). All of these techniques are used to help doctors diagnose and treat medical conditions.
