- 0.7 T MRI
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
0.7 T MRIDevice
Our scanner is based on a unique high-temperature superconducting magnet that is highly compact, weighs only 400 kg, and requires no cryogens. Its innovative design allows the subject to sit normally with sightlines to the room and produces low acoustic noise during scanning.
| Study group | Role | What they receive |
|---|---|---|
| 0.7 T MRI | Experimental | Not described Receives: Device: 0.7 T MRI |
What is being measured
The primary outcome is the main question the study is designed to answer.
Image Quality
The study will quantitatively compare images obtained at 0.7 Tesla (obtained with new methods and instrumentation) with images obtained with conventional MRI. The metrics to be assessed include: spatial resolution, signal-to-noise ratio, signal-to-artifact ratio, contrast-to-noise ratio, and geometric distortion.
Measured: Day 1

Questions about this trial
What is this clinical trial studying?
A study testing 0.7 T MRI in people with Brain Imaging, run by University of Minnesota at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 2 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Michael Garwood, PhD (612-626-2001, gar@umn.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Image Quality (time frame: Day 1). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Mar 2026.
