MRI for Appendicitis: Gold Standard or Emerging Technology with Limited Role?
Although computed tomography (CT) is the preferred imaging modality to diagnose appendicitis, magnetic resonance imaging (MRI) is growing in availability and is gaining popularity as an alternative imaging tool for potential appendicitis. MRIs do not emit ionizing radiation. As opposed to ultrasound, MRI allows for visualization of potential alternate diagnoses. CT and MRI have similar sensitivity and specificity for the diagnosis of appendicitis. While MRI may be costlier and take longer to perform than CT, protocols have been created to expedite the process and decrease costs. Hence, MRI is a reasonable alternative to CT in the acute care setting if available.
