Clinical Trial: Magnetic Resonance Imaging (MRI) of Appendicitis in Children

Study Status: Completed
Recruit Status: Completed
Study Type: Interventional

Official Title: Magnetic Resonance Evaluation of Appendicitis in Children Aged 8-18

Brief Summary: Study to find out if MRI can diagnose appendicitis in children as well as or better than CT scan and/or ultrasound scan performed at the same time. No additional contrast material or sedation will be used to perform the MRI.

Detailed Summary:
Sponsor: Children's Research Institute

Current Primary Outcome: Diagnostic Sensitivity/Specificity and Accuracy of Appendiceal MRI Comparedsurgical Findings or Clinical Follow-up [ Time Frame: during diagnostic procedure ]

Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV)


Original Primary Outcome: 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 ]

Current Secondary Outcome:

Original Secondary Outcome:

  • Duration of MRI scan and effect on emergency department disposition of potential patients with appendicitis [ Time Frame: At time of scan ]
  • Cost-effectiveness of appendiceal MRI compared to CT scan or ultrasound [ Time Frame: At time of scan ]
