Study Background

Researchers at Johns Hopkins University are improving the way Magnetic Resonance Spectroscopy (MRS) is done. MRS is a technology that allows us to non-invasively measure levels of brain chemicals using an MRI scanner.

In order to develop new MRS techniques, we need to test normal, healthy participants across the whole lifespan. This testing is necessary to compare the improved MRS techniques to existing methods and to ensure that these new methods are working properly for all age groups.

Participants will attend one study visit lasting approximately 1.5 hours. Children should not be claustrophobic and must be able to lay still in an MRI scanner for one hour.

Additional Information

This research is being done to improve the way Magnetic Resonance Spectroscopy (MRS) is done.

You may qualify for this study if you meet the following criteria.

Key Criteria:

  • Ages 5-17
  • No significant physical or mental conditions
  • Able to undergo an MRI scan (no metal in the body, no claustrophobia)
  • No psychiatric conditions (depression, anxiety, bipolar disorder, schizophrenia)
  • No behavioral conditions (autism, ADHD, conduct disorder)

Once enrolled, this 1.5 hour study involves:

  • Visiting the Kennedy Krieger Institute on the Johns Hopkins Hospital campus in Baltimore, MD
    • A member of the study team will meet the family at the parking garage and escort them to the MRI scanner
    • A member of the study team will receive informed consent/parental assent
    • An MRI technologist will screen the participant for their eligibility to safely receive an MRI scan
  • Completing a 1-hour MRI scan
    • The participant will be asked to lay still in the MRI scanner for this entire duration
    • They may sleep, or if desired, they may have the option to listen to music or watch a movie during their scan.

Following the 1-hour scan, the participant will receive $50 in compensation, as well as a free parking voucher.

There is no cost for you to participate in this study.
