AMRIS is an NMR/MRI auxiliary located at the McKnight Brain Institute of the University of Florida that supports UF research groups and operates an international user facility for the NSF-funded National High Magnetic Field Laboratory (NHMFL). Equipment in the facility was acquired through support from the NIH, NSF, and Department of Defense.

Access for users external to UF and technology development time are available through the NHMFL Users Program. Please review our reservation and billing policies prior to making your reservations, as this includes our policy regarding cancellations. AMRIS magnet time should be requested by the 15th of the month prior to the reservation. Reservations must be made using the online request form.

Please remember that ALL publications containing data collected at AMRIS must acknowledge the National Science Foundation Cooperative Agreement.  Also, several instruments were purchased with NIH equipment funds; data collected using these instruments should acknowledge the appropriate NIH grants.  Sample text for facility and instrumentation acknowledgement is available.

Mystery of the Origin of MRI Signal in Stroke Solved

MRI scans taken after a stroke show brightness around the injury, the origins of which have been a long-standing and vexatious mystery for scientists. This work suggests these MRI signal changes result from fluid changes in glial cell volumes, results that could advance our ability to distinguish reversible and irreversible stroke events or provide a better understanding for other disorders such as Parkinson's, Alzheimer's, and mood or sleep disorders.

Prevention: Whether you will be coming in person or making arrangements with a staff member to submit your samples for remote analysis, you must request the instrument time through our online request form. Before coming, please take into account any possible risk to staff and subjects, particularly those that may have an existing vulnerable health condition, versus the need to work in person. Please reference the CDC website for guidance in making this decision.

The University of Florida campus is following CDC guidance to prevent the spread of the novel coronavirus SARS-CoV-2, aka COVID-19. We have developed safety SOPs to maintain our equipment and clean the commonly touched objects and surfaces, but please help us by doing your part to stay healthy. We request that you wear a face mask in all settings where you anticipate close contact with another person outside your immediate household. Wash your hands often with soap and water for at least 20 seconds. If soap and water are not available, use an alcohol-based hand sanitizer. Please stay home if you are sick or if you recently (last 14 days) visited an area where COVID-19 cases are spiking.

As a reminder, we continue to enforce our standard cancellation policy for billing purposes, but we do ask that you notify us as soon as possible whenever reservations must be cancelled. Whether you need to cancel your reservations or postpone studies, simply indicate COVID-19 as the reason when you submit the cancellation (no further details are necessary).
