An abdominal CT scan provides detailed images of the structures in the belly area. During the scan, the patient lies on a table that slides into a CT machine. The machine's x-ray beam rotates around the patient to create separate images of slices within the belly area. A computer assembles these slices to form 3D models. Abdominal CT scans are used to investigate abdominal pain, swelling, fever, masses, tumors, infections, injuries, kidney stones, and appendicitis. Abnormal results may indicate various cancers, gallbladder, liver or pancreatic problems, kidney stones, aneurysms, or other issues. The scan can image structures like cysts, enlarged organs, renal cysts, diverticulitis,

How the CT is performed? You will lie on a narrow table that slides into the center of the CT scanner. Most often, you will lie on your back with your arms raised above your head. Once you are inside the scanner, the machine's x-ray beam rotates around you. Modern spiral scanners can perform the exam without stopping. A computer creates separate images of the belly area. These are called slices. These images can be stored, viewed on a monitor, or printed on film. Three-dimensional models of the belly area can be made by stacking the slices together. You must be still during the exam, because movement causes blurred images. You may be told to hold your breath for short periods of time.
Why the Test is Performed An abdominal CT scan makes detailed pictures of the structures inside your belly (abdomen) very quickly. This test may be used to look for: Cause of abdominal pain or swelling Hernia Cause of a fever Masses and tumors, including cancer Infections or injury Kidney stones Appendicitis
What Abnormal Results Mean The abdominal CT scan may show some cancers, including: Cancer of the renal pelvis or ureter Colon cancer Hepatocellular carcinoma Lymphoma Melanoma Ovarian cancer Pancreatic cancer Pheochromocytoma Renal cell carcinoma (kidney cancer) Testicular cancer
The abdominal CT scan may show problems with the gallbladder, liver, or pancreas, including: Acute cholecystitis Alcoholic liver disease Cholelithiasis Pancreatic abscess Pancreatic pseudocyst Pancreatitis Blockage of bile ducts Kidney stones Kidney or ureter damage Polycystic kidney disease
Abnormal results may also be due to: Abdominal aortic aneurysm Abscesses Appendicitis Bowel wall thickening Retroperitoneal fibrosis Renal artery stenosis Renal vein thrombosis
Structures visible:
ABDOMINAL CYST An abdominal CT scan revealed a large right upper quadrant cyst measuring 14x17x21 cm ( lateral, anteroposterior and craniocaudal)There was mass effect upon the liver and duodenum. The cyst had a thin smooth wall with internal fluid and high density material consistent with a blood clot.
HEPATOMEGALY
SPLENOMEGALY
RENAL CYST NO CONTRAST CONTRAST
DIVERTICULITS
ABDOMINAL ABSCESS Psoas abscess (blue arrow), and abscess dissecting anteriorly in transversalis fascia.
RENAL STONE
PHEOCHROMOCYTOMA Pheochromocytoma is a tumor of the adrenal gland that causes excess release of epinephrine and norepinephrine, hormones that regulate heart rate and blood pressure
CIRRHOSIS
CHOLELITHIASIS
CHOLECYSTITIS
PANCREATIC CANCER
PANCREATITIS
ABDOMINAL ANEURYSM
