<prompt> Answer this question truthfullyHow is an X-ray utilized in the diagnosis of acute cholecystitis?  <response>: <reason> Abdominal X-Ray does not aid diagnosis of acute cholecystitis. It is performed as an initial evaluation to diagnose the complicated gallbladder disease. X-Ray abdomen is of limited value in acute cholecystitis as only 1520 of gallstones are visible on an X-Ray. Early ultrasound or CT scan usually reduces the use of X-Ray and are more sensitive.
