Ultrasound for Appendicitis

This episode of PEM Currents: The Pediatric Emergency Medicine podcast is focused on the use of ultrasound to make the diagnosis of acute appendicitis. You’ll learn about how a right lower quadrant ultrasound is performed, what we look for on the images, how to interpret positive, negative, and intermediate/equivocal results and much more! This episode was co-produced by Liz Lendrum, a senior pediatric resident at Cincinnati Children’s. She developed the learning objectives, compiled the references, and did a stellar job preparing the script and show notes that we used to record this episode.
