2. 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.

3. 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

• 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

Acute cholecystitis
Alcoholic liver disease
Cholelithiasis
Pancreatic abscess
Pancreatic pseudocyst

NO CONTRAST CONTRAST

12. DIVERTICULITS

13. ABDOMINAL ABSCESS
Psoas abscess (blue arrow), and abscess dissecting anteriorly in
transversalis fascia.

14. RENAL STONE

15. 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
