Latest MRI Technology for Brain Care
How MRI works
Magnetic resonance imaging (MRI) shows high-resolution images of tissue and blood flow
- High-power magnets align hydrogen molecules in the body
- Radio wave pulses are transmitted into the body to disturb this molecular alignment
- Images are created from new radio signals that are generated when hydrogen molecules return to alignment
- Magnetic field strength is measured in units called "Teslas"
How MRI has evolved over time
- Since the first human scan in 1977, MRI scanners have evolved in speed, convenience and power.
- 7 Tesla provides clearer images than earlier 1.5 or 3 Tesla MRI scanners.
- Most MRI scanners in the U.S. are 1.5 or 3 Tesla units. 7 Tesla is now the most powerful MRI strength available for patient use.
7 Tesla MRI: Higher resolution for greater diagnostic precision
The newest medically-approved MRI scanners are 7 Tesla, which before now were only used for research. As shown in the diagnostic images below, the 7 Tesla MRI offers resolution much higher than the more common 3 Tesla scanners. Greater resolution allows the person's care team to identify subtle abnormalities related to their condition. In some instances, this can improve treatment of the disease.
A higher resolution scan may offer new answers
People with a wide range of neurological issues may benefit from the 7 Tesla MRI. With the help of a doctor, the new scanners may provide new answers for:
Detect abnormalities that may be the source of seizures.
Assess functional areas of the brain to plan for complex surgery, including the removal of brain tumors.
More accurately detect very tiny aneurysms.
Degenerative and demyelinating disorders
More clearly identify multiple sclerosis or amyloid angiopathy.
Trauma and concussion
More accurately detect even the slightest brain bleeding from head injury.
Brain vascular malformations
Detect and more accurately characterize abnormal blood vessels in the brain.
