Magnetic Resonance Imaging (MRI)
Definition
MRI is a type of imaging technology that uses magnetic fields and radio waves to create detailed images of the organs and tissues within the body.
Analogy
Think of an MRI like a super-powered camera. Just as a camera captures images of visible light, an MRI captures 'images' of magnetic fields. It's like having X-ray vision that can see through your skin and bones to capture pictures of your internal organs.
