Abdominal computed tomography (CT) scanning has revolutionized patient care in the past two decades. The introduction of CT technology is widely viewed by medical practitioners as one of the major medical advances.  Abdominal CT scanning is used in the evaluation of trauma victims for visceral injury  and in the evaluation of acute abdominal pain, with a major role in the evaluation of renal calculi,  acute appendicitis,  and complex abdominal pathology (see the images below). 
Scan protocols are adapted for the specific diagnostic problem, and the images are reformatted for viewing on picture archiving and communication system (PACS) workstations. Additional manipulation can be done on PACS or dedicated workstations, providing for multiplanar and 3-dimensional views of organs, vessels, and bones. With the use of appropriate luminal and intravenous contrast agents, information can be obtained on lesion characteristics based on tissue attenuation changes, detailed 3-dimensional arterial anatomy, and/or luminal surface contour (eg, in virtual colonoscopy).
Abdominal CT scanning is used in the emergency setting to diagnose complex intra-abdominal conditions, to differentiate causes of bowel obstruction, and to evaluate complications of hernia, pancreatitis, biliary obstruction, acute vascular compromise, and abdominal aneurysm.
Multidetector CT (MDCT) has a major role in characterization and staging of tumors of the liver, pancreas, kidneys, bowel, reproductive organs, and lymphatic system. It also has a role in screening for hepatocellular carcinoma  and colon carcinoma using virtual colonoscopy. [7, 8, 9]
It is also used in surgical treatment planning and in the diagnosis of postoperative complications.
