Many
commonly asked questions about MR are answered here, but should you
have any other questions or concerns, please feel free to consult
your doctor.
Why
are MR scans important?
MR scans allow doctors to see images of your internal organs and structures
in great detail from many angles. This gives them information more
quickly, and in many cases more economically, than past tests and
exploratory surgeries.
Is
an MR scan like an X-ray?
No. An MR scan uses a powerful magnet in conjunction with radio frequency
waves to generate images of your internal organs and structures without
radiation
How
long will the exam take?
That will depend on what is being studied, but a typical exam lasts
between 20 and 60 minutes. You should allow extra time in case the exam
lasts longer than expected.
Does
the machine make a lot of noise?
The magnet makes a slight rapping sound as images are being taken. In
between scans the machine is quiet. Headphones are available and you
are welcome to bring your own CD’s for your enjoyment, but their
use will not prevent you from hearing the technologist if he or she
speaks to you during the exam.
Do I have to hold still the whole time?
It is important for image clarity and the best scan results to hold
still during the exam. The technologists will instruct you as to when
you may move between scans. Keep in mind a routine exam may take at
least 20 minutes.
Will
I be alone?
You will be in contact with a technologist at all times. Even when he
or she is not in the MR room, you will be able to talk to him or her
by intercom. In some cases a family member is welcome to stay in the
room with you during your scan.
