Sagittal MRI Image of Brain
Caption:
A sagittal magnetic resonance image (MRI) of the brain. NSF-supported fundamental research led to the development of MRI technology. [See related images: First Magnetic Resonance Scanner and First Human MRI Scan.]
More about this Image
Fundamental research, supported by the NSF, led to the development of magnetic resonance imaging (MRI) technology. MRI is widely used in hospitals for purposes like detecting tumors and internal tissue damage in patients, and investigating differences in brain tissue.
MRI technology works like this. An MRI imager surrounds a patient with magnets. The magnetic field created by the magnets causes atomic nuclei in the patient’s body to line up parallel to the field. A coil in the imager jars the nuclei with radio waves. They resonate, producing a faint radio signal that a computer amplifies and translates into an image. Unlike X-rays or CAT scans, MRI lets doctors distinguish blood vessels from malignant tissue.
