Monthly resident rotation. EUS training is an ACGME requirement for emergency medicine residencies. This rotation is the core training component of that requirement. In additional, there is a EUS elective that many, if not most, EM residents take in the fourth year of training to hone their skills.  Medical students may join the division for a 2-4 week EUS elective.


Current and recent projects include:

  • REASON – EUS in cardiac arrest (multi-center study)
  • STONE – Utility of point-of-care ultrasound in renal colic (multi-center study)
  • STUSI – Defining soft tissue pathology (multi-center study)
  • Aortic Valve Measurement – Point-of-care valve measurements in emergency department patients.
