Anatomical orientation

Aetiology: Pancreatic: Acute or chronic Pancreatitis. Hepatic: hepatitis, hepatic abscess. Gastric:gastritis Duodenal :Duodenal ulcer,duodenitis. Biliary :Cholecystitis,choledocholithiasis. Renal : stones,pyelonephritis. Aortic :Dissecting aortic aneurysm. Splenic: Infarction (Sickle cell crisis) Large bowel: Colitis. Referred pain :e.g.pneumonia,spondylosis.

Methods of Examination Plain x-ray Barium studies. Ultrasonography Computed tomography. Isotopic scan (e.g.: Cholecystitis) MRI :MRCP Arteriography.

Rationale of imaging Clinical data of the patient.

Abdominal trauma On evaluation, urgent life-threatening injuries,

such as a large hemoperitoneum, a large or tension pneumothorax, or active arterial extravasation, should be sought out first.

This should be followed by a thorough interrogation for injury of the abdomen and pelvis: liver and right paracolic gutter; spleen and left paracolic gutter; upper abdominal organs, arterial tree; retroperitoneum; small bowel, colon, and mesentery.

Clinical evaluation of the patient is the first step in the diagnosis.

Choose the appropriate imaging modality.
