Abdominal Ultrasound

Ultrasound, Abdominal

Results

An abdominal ultrasound uses reflected sound waves to produce a picture of the organs and other structures in the abdomen.

Abdominal ultrasound

Normal:	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 abdomen.
	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.
Abnormal:	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 seen.
	The liver may appear abnormal, which may indicate 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 indicate 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 gallbladder.
	The kidneys may be enlarged because of urine that is not draining properly through the ureters. 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 occurred).
