About Your MR Scan
Q. Why are MR scans important?
A. 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.
Q. Is an MR scan like an x-ray?
A. No. An MR scan uses a powerful magnet in conjunction
with radio frequency waves to generate images of your
internal organs and structures. It’s one of the least invasive
tests that can see inside the body.
Q. How long will the exam take?
A. That will depend upon 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.
Q. What if I have claustrophobia?
A. The Philips 1.0 NT has a flared opening and a large diameter to help reduce claustrophobia. Please inform
scheduling if you’re claustrophobic.
Q. Does the machine make a lot of noise?
A. The magnet makes a slight rapping sound as images are
being taken. In between scans the machine is quiet. The
MR technologist will provide you with hearing protection,
but its use will not prevent you from hearing the technologist
if he or she speaks to you during the exam.
Q. Do I have to hold still the whole time?
A. It is important for image clarity and the best scan results to
hold still during the exam. The technologist will inform you
when you may move between scans. Keep in mind a
routine exam can take at least 20 minutes.
Q. Will I be alone?
A. You will be in contact with the 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 via intercom. In some cases a family member is welcome to stay in the room with you during
your scan.
Q. Will I need a contrast agent?
A. Your MRI exam may require a contrast agent usually by intravenous route. MR scans do not usually require oral
contrast. If your exam does require contrast, be sure to notify the technologist if you have any history of allergies
or kidney disease.
