The Role of Contrast Enhanced Ultrasound in Appendicitis

This will be a single-center, non-randomized trial that will add to our institution's current diagnostic algorithm using Contrast Enhanced Ultra Sound (CEUS) in subjects who are clinically suspicious for acute appendicitis. For those who consent to study participation, we propose obtaining a CEUS after the initial gray-scale ultrasound. Once the initial ultrasound is complete, the contrast Lumason® (sulfur hexafluoride lipid type-A microspheres) will be administered through an already existing IV catheter and an abdominal scan will be completed. The patient will then continue with standard of care treatment per his treating physician. The CEUS image will be read at a future time by a Children's Mercy Hospital radiologist blinded to the results of the gray scale ultrasound and computed tomography (CT) scan if one was obtained; these will be used for comparison.
