    • what is the most likely cause of pain?
    • is there evidence of infection or sepsis?

  • investigations
    • route of investigation depends on the question:
      • US
        • gallbladder and biliary tree
        • renal tract
        • appendicitis
      • erect CXR
        • perforation
      • AXR
        • may give some information about bowel dilatation
        • may highlight perforation and free intraperitoneal gas
        • often difficult to assess and of low yield
        • AXR use will very much depend on where you work
      • CT
        • general workhorse for much abdominal investigation
          • non-contrast for renal stones
          • portovenous phase for most work
          • arterial phase for vascular work
  • making the request
    • know what question you are trying to ask
    • know what the renal function is if the patient is for CT
    • if in doubt, as the radiologist oncall
  • common pathology
