radiologist may discuss initial results of the MRI
with you right after the test. Complete results are usually available for your
doctor in 1 to 2 days.
An MRI scan can sometimes find a problem in
a tissue or an organ that is not seen by
CT scan, even when the size and shape of the tissue or
organ looks normal.
Magnetic resonance imaging (MRI) of the abdomen
The organs and blood vessels are normal in
size, shape, and location.
No abnormal growths, such as tumors, are
No blockage is found in the ducts draining
the liver, gallbladder, or pancreas.
No blockage is found in the tubes (ureters) that lead out of the kidneys.
No bleeding, abnormal collections of fluid,
blockage in the flow of blood, or bulges in the blood vessels (aneurysms) are present.
No signs of inflammation or infection are
An organ is too large, too small, or in
the wrong place. The MRI also may show areas of scarring or injury.
Growths are found, such as tumors that
could be either benign or cancerous. Signs of infection may be
A collection of fluid is present, which
could mean you have internal bleeding or an infection.
A bulge in the wall of a blood vessel
(aneurysm) is present. Blockage in or narrowing of a blood vessel also may be
Blockage is present in the
bile ducts. Reasons for the blockage may include a
gallstone, tumor, infection, or inflammation.
Blockage is present in the tubes leading
from the kidneys (ureters). Reasons for the blockage may include a kidney
stone, tumor, infection, or inflammation.
What Affects the Test
Reasons you may not be able to
have the test or why the results may not be helpful include:
Pregnancy. An MRI test usually is not done
during pregnancy. In some cases, an MRI could be safely done late in your
pregnancy if your doctor wants to check your belly or your developing baby for
Medical devices that use electronics, such as a pacemaker
or medicine infusion pump. The MRI magnet may cause problems with these
Medical devices that contain metal, which can make some of
the detailed MRI pictures blurry. This may prevent your doctor from seeing the
organ that is being looked at. For example, an
intrauterine device (IUD) that contains metal may
prevent your doctor from seeing the uterus clearly.
If you are not
able to remain still during the test.
Obesity. A person who is very overweight may not fit
into standard MRI machines.
What To Think About
Sometimes your MRI test
results may be different than those from CT, ultrasound, or X-ray tests because
the MRI scan is more specific.
Open MRI machines are now made so that the magnet does not
completely surround you. Open MRI is useful for people who are claustrophobic
or obese. But these machines are not available everywhere. Also, these machines
may not be able to do all the studies needed to check for
