The acute abdomen is one of the most frequent causes for presentation to the emergency department. Imaging plays an important role for an accurate diagnosis, which in turn diminishes morbidity and mortality Jastaniah and Salih demonstrate optimum CT aspects and emphasize on the important features of CT for those patients presenting with an acute abdominal pain at the Emergency Department. The reported data by this study are based on the author working experience, which forms a continuous protocol adjustment process. The present study provides evidence that CT would result in definite diagnosis of patients with abdominal pain in terms of the detection of some urgent conditions . The acute abdomen may be defined generally as an intra-abdominal process causing severe pain and often requiring medical or surgical intervention. The acute abdomen is a frequent entity at the Emergency Department, the acute abdomen may be life threatening and so rapid diagnosis of patients presenting with acute abdominal pain is required . Diagnostic work-up with imaging can consist of plain X-ray, ultrasonography (US), computed tomography (CT) and even diagnostic laparoscopy. During the last decade, a trend towards increased use of computed tomography in patients with abdominal pain can be seen. In general, acute abdominal pain is responsible for about 10% of total number of patients visiting the emergency. Quick and precise diagnosis for the urgent cases is usually vital for treatment. Medical imaging is commonly used for the diagnosis of most acute abdomen pain. Abdomen and pelvis are reviewed by CT scan. Specifically, in cases of acute abdomen complain.

There is no gold standard for diagnosis of acute abdomen as it still a matter of cooperation between clinical data, radiological and laboratory worker. The aim of this study was to demonstrate optimum CT aspects and emphasize on the important features of CT for those patients presenting with an acute abdominal pain clinically suspected to have emergency operation .

Inclusion Criteria:

• Any Case Of Acute Abdominal Pain suspected to be surgical cases in adults.

Exclusion Criteria:

• If pediatric .
• If associated with pregnancy.
• The patient have severe cardiac or respiratory disease ,cant to lie supine.

The aim of this study is to improve diagnostic efficiency dealing with acute abdomen not to stabilize a new technique.
