What is 7T MRI?
Why 7T?

7T MRI is a non-invasive imaging devices that uses ultra-high magnetic field of 7 Tesla to scan human body. 7T MRI does not expose patients to ionizing radiation (like X-ray), and some 7T MRI systems have been cleared by FDA for clinical use
The most important benefit of 7T MRI is high signal-to-noise ratio (SNR) and high sensitivity that allow doctors and researchers to see intricate anatomical details (often with sub-millimeter resolution) and to measure various functions of the human body. 7T MRI makes many new features visible to doctors that would otherwise not visible at standard field strength of 1.5 and 3T.
To date, clinical benefits of 7T MRI have been shown in a range of neurologic disorders including epilepsy, multiple sclerosis (MS), planning for deep brain stimulation (DBS), cerebral small vessel disease (cSVD) as well as musculoskeletal (MSK) imaging. Visit For providers for details.
