This procedure is also called nuclear magnetic resonance imaging.

Superconductivity is already used in many applications that justify the expense, including a medical diagnostic technique called magnetic resonance imaging.

At least that is the judgment of the researchers who track increased blood flow with brain scans called functional magnetic resonance imaging.

They also used a technique called magnetic resonance imaging (MRI) to study the creature's internal organs.

Similar basic research has made it possible for doctors to identify abnormalities in the brain, the spinal cord and other organs through a diagnostic technique called magnetic resonance imaging.

Hospitals and clinics use the same technology, called magnetic resonance imaging, or M.R.I., to scan the tissues of the human body.

Now the public is being dazzled once again by a technique called functional magnetic resonance imaging, or F.M.R.I., which is finding precise brain locations related to all sorts of human traits and activities.

A technology called functional magnetic resonance imaging can reveal which part of your brain is most active when you're solving a mathematical puzzle, say, or memorizing a list of words.

The tool making that possible is called functional magnetic resonance imaging, or fast M.R.I. Conventional M.R.I. machines employ strong magnets and radio waves to make sectional images of the brain's anatomy.

Yet a relatively new type of scan called functional magnetic resonance imaging (fMRI) takes the technology one step farther.
