Unspecific location

In acute abdominal pain with otherwise no specific indication of its origin, a CT of the abdomen and pelvis is generally indicated.

Cholecystitis is indicated by upper right quadrant pain and signs of infection.
Choice of modality:

  • Abdominal CT may be used if complications such as perforation or gangrene are suspected.[4] In adults, acute abdominal symptoms that are rather unspecific also indicate CT.


This is indicated in right upper quadrant pain without signs of infection.
