SCAN (pronounced /skæn/), is a medical term that refers to the process of capturing images of the body's internal structures using various imaging technologies. The term is derived from the Latin word scandere, meaning "to climb" or "to scan".
Types of SCAN

- Magnetic Resonance Imaging (MRI) Scan: An MRI scan uses a large magnet and radio waves to look at organs and structures inside your body.
- Positron Emission Tomography (PET) Scan: A PET scan uses a small amount of radioactive material (tracer) to show how tissues and organs are functioning.
- Ultrasound Scan: This type of scan uses high-frequency sound waves to create images of the inside of the body.
