Final answer:
Magnetic Resonance Imaging (MRI) is a noninvasive medical imaging technique that uses magnetic fields and radio waves to create detailed images of internal tissues and organs.
Step-by-step explanation:
Magnetic Resonance Imaging (MRI) is a noninvasive medical imaging technique that uses magnetic fields and radio waves to create detailed images of internal tissues and organs. It works by subjecting hydrogen nuclei in soft tissues to fluctuating magnetic fields, causing them to emit their own magnetic field. This signal is then read by sensors in the machine and interpreted by a computer to form a detailed image.
