Final answer:
MRI is a non-invasive medical imaging technique that uses magnetic fields to create detailed images of internal tissues and organs. It is most accurately identified as an example of a medical imaging technique in the field of physics.
Step-by-step explanation:
MRI stands for Magnetic Resonance Imaging and is a non-invasive medical imaging technique that uses magnetic fields to create detailed images of internal tissues and organs. It is most accurately identified as an example of a medical imaging technique in the field of physics.
MRI works by applying an external magnetic field that interacts with the nuclei of certain atoms, particularly hydrogen nuclei or protons. These nuclei possess their own small magnetic fields, which result in radio signals that can be detected and used to produce images.
Some key applications of MRI include providing highly detailed images for diagnosing conditions such as tumors, strokes, infections, and injuries. Since MRI does not involve exposing patients to radiation, it offers a safer alternative to other imaging techniques.
