Choice of modality

  • Right upper quadrant abdominal ultrasonography of cholecystitis is generally the first exam of choice.[1][2][3]
  • 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.
