Physiological and Psychosomatic Effects of Exposure to MRI Scanning Environment
An observational study of Healthy Volunteers, run by National Institute of Neurological Disorders and Stroke (NINDS).
Trial 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. Read more about this study

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.

Objective
The goals of this pilot study are to establish a normative database of vital signs, cognitive function and unusual subjective sensations in a 0T scanner. This data will be used as a reference for a future study of the effects of exposure to a 11.7T static magnetic field.
Study Population
26 healthy volunteers, aged 22-65.
Accrual ceiling =50
Accrual Target =26
Drop outs will be replaced
Design
The study consists of one outpatient screening session and one experimental session. Informed consent and a history and neurological examination will be carried out at the screening visit. Vital signs (pulse oximeter, heart rate, respiratory rate and skin temperature) will be measured immediately before and after the experimental scan session, and pulse oximeter, heart rate and respiration will be monitored when the subject is in the scanner. Subjects will remain in the scanner for approximately 1 hour. During the experimental session, while the subject is in the scanner, they will be asked to carry out a brief test of attention at 10-15 minute intervals, up to 3 times during the session. At the end of the experimental session, subjects will fill out the MRI exit questionnaire to rate subjective sensations such as nausea, vertigo, and lightheadedness, on a Likert scale and complete a computerized neuro-cognitive test battery.
Outcome Measures
The objective of the study is to obtain a normative dataset of neuropsychological test measures, physiological parameters, and subjective experiences measures in subjects undergoing 0T exposure.

Questions about this trial
What is this clinical trial studying?
An observational study of Healthy Volunteers, run by National Institute of Neurological Disorders and Stroke (NINDS).
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 4 inclusion and 13 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: withdrawn, as of the sponsor's last update on 17 Dec 2019. Status can change between updates, so confirm with the study contact before making plans.
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?
The study was withdrawn before enrolling participants, so there are no results.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Neuropsychological tests (time frame: 2 years). The study lists 3 primary outcomes in all. 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 17 Dec 2019.
