Summary

Background:

\- Magnetic resonance imaging (MRI) creates high-quality images of the human body without x-rays. It uses a strong magnetic field and radio waves to take pictures. Researchers want to test a scanner that uses a high magnetic field strength.

Objective:

\- To study how the body responds to being in a high field 11.7T MRI scanner.

Eligibility:

\- Healthy people ages 22 65.

Design:

* Participants will be screened with a medical history and physical exam. They will complete a healthy volunteer questionnaire and an MRI safety screening form. They may have a 3T MRI scan of the brain.
* Participants will have an MRI scan. They will lie on a table that will slide in and out of the MRI cylinder very slowly. They will be asked to lie still.
* Participants will do simple tasks while inside the machine. These can include listening and responding to questions, tapping fingers, or moving a hand.
* While in the scanner, participants will hear loud knocking noises. They will get earmuffs.
* Right when they exit the scanner, participants will get a questionnaire to fill out. This will ask about how they felt inside the scanner.
* During the MRI, participants heart rate, respiratory rate, and skin temperature will be measured. Before and after the scan, these things plus blood pressure will be measured.
* Participants will be tested before and after being in the MRI scanner. They will answer questions, take pen-and-paper or computer tests, and do simple actions. Their sense of smell may be tested.
