Other imaging studies

  • Kidneys-ureters-bladder radiographs: Insensitive, nonspecific, and not cost-effective

  • Barium enema study: Has essentially no role in the diagnosis of acute appendicitis

  • Radionuclide scanning: Localized uptake of tracer in the RLQ suggests appendiceal inflammation

  • MRI: Useful in pregnant patients if graded compression ultrasonography is nondiagnostic
