There are no known risks from having an abdominal
ultrasound uses reflected sound waves to produce a
picture of the organs and other structures in the abdomen.
The size and shape of the
abdominal organs appear normal. The liver, spleen, and pancreas appear normal
in size and texture. No abnormal growths are seen. No fluid is found in the
The diameter of the aorta is
normal, and no
aneurysms are seen.
The thickness of the
gallbladder wall is normal. The size of the bile ducts between the gallbladder
and the small intestine is normal. No
gallstones are seen.
The kidneys appear as sharply outlined
bean-shaped organs. No
kidney stones are seen. No blockage to the system
draining the kidneys is present.
An organ may appear abnormal because of
inflammation, infection, or other diseases. An organ may be smaller than normal
because of an old injury or past inflammation. An organ may be pushed out of
its normal location because of an abnormal growth pressing against it. An
abnormal growth (such as a tumor) may be seen in an organ. Fluid in the
abdominal cavity (ascites) may be seen.
The aorta is enlarged, or an aneurysm is
The liver may appear abnormal, which may
point to liver disease (such as
cirrhosis or cancer).
The walls of the gallbladder may be
thickened, or fluid may be present around the gallbladder, which may point to
inflammation. The bile ducts may be enlarged because of blockage (from a
gallstone or an abnormal growth in the pancreas). Gallstones may be seen inside
The kidneys or the tubes that drain the
kidneys (ureters) may be enlarged because of urine that is not
draining properly. Kidney stones are seen within the kidneys (not all stones
can be seen with ultrasound).
An area of infection (abscess) or a fluid-filled
cyst may appear as a round, hollow structure inside an
organ. The spleen may be ruptured (if an injury to the abdomen has
