The purpose of this study is to compare IV contrast only vs. IV and oral contrast Computed Tomography (CT) for the diagnosis of acute appendicitis in adult patients in our emergency department. A secondary purpose will be to design a specific CT for appendicitis protocol at our institution at the conclusion of this study.

Further study details as provided by WellSpan Health:

Primary Outcome Measures:
  • sensitivity of IV contrast alone for a computed tomography scan for the diagnosis of appendicitis in the adult Emergency Department patient. [ Time Frame: immediate reading + blinded reading within 48 hours ]

Secondary Outcome Measures:
  • If IV contrast alone for CT scan is sensitive for the diagnosis of appendicitis in the adult Emergency department patient [ Time Frame: immediate reading and blinded reading within 48 hours ]
