Information for Subjects

If you are scheduled to participate or are considering participating in a research study you may find the following information helpful:

  • We will ask you several questions to determine whether you are eligible to participate. All information that you provide will be kept confidential. For studies that involve use of MRI or magnetoencephalography (MEG), please let us know if you have any type of metal implant in your body. Many types of implants are acceptable, but some are not. Therefore, it's important that you let us know your specific situation.

  • We will provide you a detailed explanation of the study protocol. You will be compensated for participating in a research study. The compensation rate will be discussed with you. You will have an opportunity to discuss the protocol and ask any questions you may have.

  • Unless otherwise directed, you may follow all your normal habits and diet on the day of your appointment.

  • Prior to scanning, you will be asked to remove all jewelry, eyeglasses, and any other metal items you may be wearing. You may be asked to change into hospital clothing that will be provided to you. This will insure that any metal in your clothing does not interfere with scanning. If you are wearing makeup that contains metallic specks, you may be asked to remove this before your scan.

  • Appointments generally last from 1-4 hours, depending on the nature of the study. If you are involved in a multi-part study, you may be asked to return at another date for additional scanning.
