Despite its limitations, abdominal radiographyremains the initial imaging study in patients withabdominal symptoms, particularly in those with possible intestinal obstruction. Its diagnostic value tendsto be highest in patients with signs or symptoms ofbiliary or urinary system calculi, intestinal obstruction, perforation, or ischemia. Plain films are leasthelpful in patients with vague abdominal pain andnonspecific physical findings. Its role in the evaluation of calculi, perforation, or ischemia has beenreplaced by CT.
