- What is an MRI?
- An MRI - Magnetic Resonance Imaging - uses the
power of magnets to create images of the inside
of your body. In our study we will be taking
images of your brain.
- What is involved in getting scanned by the MRI?
- For the scan, you will lie on a table with your head
and upper body in the scanner (which is shaped
like a tube). In order to help you hold your
head still, and to produce the best images, there
is a head-holding frame with cushions.
During the scan the machine makes a loud knocking
sound.
- Will getting scanned by the MRI hurt?
- No, the MRI is a non-invasive method of studying
your brain. Although it is noisy, you will not
feel anything. You will be wearing a headset
during the scan to reduce the noise. If
you want, you can listen to the radio or a
CD you bring during the scan.
- Does the MRI scan involve radiation?
- The MRI scan does NOT use any radiation.
- Are there any risks to getting scanned
by the MRI?
- There are no known serious risks or adverse effects
of MRI except in certain risk groups. Subjects
at potential risk include:
- 1- subjects with a history of metal fragments
in the eye
- 2- subjects with electrical, mechanical or
magnetic activated implants, including
pacemakers and cochlear implants.
If you are a woman of childbearing potential,
please read and acknowledge the following section.
- If I am pregnant or think I am pregnant, do I need
to notify the investigator?
- Yes. Some research procedures can cause
severe birth defects and mental retardation to a
fetus (unborn baby). If you are pregnant or think
you are pregnant it is important for you to notify
the investigator immediately.
- Is there anything else I should be aware of about
getting scanned by the MRI?
- Some persons find the small space in the MRI machine
confining and feel uncomfortable. We find that
"rehearsing" prior to the procedure helps to
ease this. However, if you should feel afraid
or unable to continue, you can request the
examiner to stop at any time.
