Further study details as provided by Children's Research Institute:

Primary Outcome Measures:
  • Diagnostic Sensitivity, specificity and accuracy of appendiceal MRI compared to ultrasound, CT scan, and gold standard of either surgical findings or clinical follow-up [ Time Frame: 6 weeks after scans obtained ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Duration of MRI scan and effect on emergency department disposition of potential patients with appendicitis [ Time Frame: At time of scan ] [ Designated as safety issue: No ]
  • Cost-effectiveness of appendiceal MRI compared to CT scan or ultrasound [ Time Frame: At time of scan ] [ Designated as safety issue: No ]
