What is Magnetic Resonance Imaging
(MRA)?
|
| Magnetic resonance angiography (MRA) is
a special type of magnetic resonance imaging (MRI)
test designed to evaluate arteries, veins, and the
flowing blood within them. MRI uses radiofrequency
waves within a strong magnetic field to generate
detailed images of internal organs and tissue. No
x-ray or radiation of any kind is necessary for an
MRI exam. |
| |
| MRA is performed without need for catheters.
This is beneficial because detailed images of blood
vessels and blood flow are obtained without having
to insert a catheter into the area of interest, so
that there is no risk of damaging an artery. In some
cases an MRI dye (gadolinium) is used to produce
an even clearer image and detailed picture. The gadolinium
is injected into a vein in the arm helping highlight
the blood vessels, making them stand out better from
surrounding tissue. |
| |
| Why would my physician order an
MRA? |
| One of the most common reasons why an
MRA is performed is to test for any narrowing or
plaque buildup in the arteries that could lead to
a harmful medical condition. It utilizes MRI technology
to detect, diagnose and aid the treatment of heart
disorders, strokes and blood vessel diseases. MRA
is a very useful way of finding problems with blood
vessels and determining how to best to treat those
problems. By conducting an MRA, surgical procedures
can be avoided. |
| |
| A MRA is performed for a variety of circumstances.
For instance, an MRA is performed on the arteries
of the neck and brain to test for any narrowing or
plaque buildup that could lead to a stroke, or for
any weakening or ballooning of the arteries (aneurysms)
that could lead to bleeding around the brain. MRA
is also performed on the arteries to the kidneys
to test for narrowing that could lead to high blood
pressure or kidney failure. It's also performed on
the pelvis and legs to look for narrowing that could
lead to painful walking. Furthermore, MRA can be
used to evaluate non-healing ulcers or to look for
blood clots in the veins. |
| |
| Is there pain and/or discomfort
during a MRA? |
| This procedure is non-invasive and there
is no pain or discomfort involved. Some of the common
distractions or discomforts include the loud tapping
noises that are often made by the machine. Also,
at times the magnet may be very close to your face.
For those people who become uncomfortable in these
situations, they can be given a mild sedative which
is nearly always effective. You also may notice a
warm feeling in the area being studied. This is normal
but you should not be afraid to communicate to the
technician if it bothers you. |
