Liver and Spleen Scan
How It Is Done
A liver and spleen scan is often done
by a nuclear medicine technologist. The scan pictures are read by a
nuclear medicine specialist.
need to take off any jewelry. You may need to take off all or most of your
clothes. You will be given a gown to wear during the test.
technologist cleans the site on your arm where the radioactive tracer will be
injected. A small amount of the radioactive tracer is then injected.
You will lie on your back on a table and a large scanning camera will be
placed right above you. It may move slowly above and around your body, scanning
for the tracer and recording pictures as the tracer moves into your liver and
spleen. The camera does not give off any radiation, so you are not exposed to
more radiation during the scan.
You may be asked to move into
different positions so the tracer spreads through the liver and spleen. You
need to lie very still during each scan so the pictures are clear. You may be
asked to hold your breath briefly during some of the scans.
liver and spleen scan takes about 1 hour.
How It Feels
You may feel nothing at all from the
needle in your vein, or you may feel a quick sting or pinch. You may find it
hard to lie still during the scan. Ask for a pillow or blanket to make yourself
as comfortable as possible before the scan begins.
Allergic reactions to the radioactive tracer are rare. Most of the tracer will be
passed from your body (through your urine or stool) in a day. Be sure to flush
the toilet right away and thoroughly wash your hands with soap and water to
prevent anyone else from being in touch with the tracer. The amount of
radiation used in the scan is so small that people can be in contact with you
following the test.
In some cases, you may develop soreness or
swelling at the injection site. Try putting a moist, warm pack on your
There is always a small chance of damage to cells or tissue
from being exposed to any radiation, even the low level radioactive tracer used
for this test.
A liver and spleen scan is a
nuclear scan that is done to look at these organs for
disease. The results of a liver and spleen scan are ready in 2 days.
Liver and spleen scan
Normal amounts of the
radioactive tracer are found in the liver and spleen. No areas of large or
small amounts of tracer are seen.
The liver and spleen are normal
in size, shape, and location.
The tracer pattern in the
liver may show diseases.
The tracer pattern shows a
abscess, a collection of blood (hematoma), a lump made
up of blood vessels (hemangioma), or a tumor.
The tracer pattern in
the spleen may not be in the right place or may show spleen tissue that was
missed during surgery to remove the spleen (splenectomy).
or spleen may be enlarged because of a disease or may have an abnormal shape
because a tumor is pressing against the organ.
Certain types of
tumors may cause large amounts of tracer to collect in the liver or
Certain types of tumors may cause no tracer to collect in
the liver or spleen.
Some conditions cause more tracer to show up in the spleen than in the liver.
