MRI
Soft tissue imaging
MRI stands for magnetic resonance imaging, a medical scanning technology that uses powerful magnets and radio waves to create detailed images of organs and tissues inside the body.
Unlike X-rays or CT scans, MRI doesn't use radiation: The doctor ordered an MRI of her knee.
The machine is a large tube patients lie inside, which can trigger claustrophobia in some people.
