• Rationale and Comments

    The diagnostic workup of acute right upper quadrant pain is informed by risk factors for cholecystitis. When acute cholecystitis is suspected, the initial imaging modality of choice is ultrasound based on availability, examination time, lack of ionizing radiation, morphologic evaluation, confirmation of the presence or absence of gallstones, evaluation of bile ducts, and identification or exclusion of alternative diagnoses. When the clinical features, examination, laboratory and ultrasound findings are congruent, no further imaging is required.
