Ultrasound

Developing and maintaining excellence in emergency department diagnostic and procedural point-of-care ultrasound.

The mission of the Division of Emergency Ultrasound (EUS) is to lead in the field of point-of-care ultrasound (POCUS) through innovation and education with the ultimate goal of improving the care of our patients. The division provides comprehensive education on POCUS to residents, medical students, faculty, and fellows. In addition, our division faculty are active researchers in numerous studies on the use of emergency ultrasound, innovations in POCUS education and technology, and improving ultrasound administration. We provide continuous quality assurance on all of the POCUS images obtained in our pediatric and adult emergency departments.

Dr. Kristin Dwyer is the director of the Division of Emergency Ultrasound (EUS), which consists of a vibrant, experienced, and dedicated group of 10 ultrasound-trained faculty, 1 sonographer educator, and 1-2 clinical POCUS fellows per year. Dr. Almaz Dessie is the Pediatric Emergency Ultrasound Director and Pediatric EUS Fellowship Director. Dr Caitlin Azzo is the adult EUS Fellowship Director. Dr. Joseph Pare is our Director of Ultrasound Research, and Dr. Jennifer Rogers is the Director of Ultrasound Education and POCUS Director at the Warren Alpert Medical School of Brown University.

The 2025 POCUS Annual Report highlights the division’s key accomplishments over the past year, including advancements in education, research, clinical initiatives, faculty achievements, and program development.

Education

Residents get EUS training throughout their four-year program. During their intern year, residents have a dedicated one month-long EUS rotation which is followed by on-shift training. There is an additional EUS elective that many senior EM residents take advantage of to hone their basic skills or develop new more advanced techniques before graduating.  PEM fellows follow a comprehensive ultrasound curriculum which spans over the course of their 3 years of training and includes scanning, teaching and image review.  Medical students from either The Warren Alpert Medical School or visiting students from other medical schools can elect to participate in a one month EUS elective where they perform ultrasound scans with faculty and residents in the emergency department. Fellows complete a one-year EUS Fellowship program that prepares EM residency graduates or PEM fellowship graduates to become fellowship directors at academic and community hospitals.

Research

Division Research

The Department of Emergency Medicine at the Warren Alpert Medical School of Brown University boasts a robust research program to support investigator-initiated research among our faculty and trainees. The Ultrasound Division consists of several grant-funded faculty scholars who are actively conducting local and multi-center POCUS investigations and have been authors on numerous landmark POCUS studies. In addition, we provide mentorship to trainees interested in conducting ultrasound-related research. Some of our current and recent projects include:

  • Impact of patient and sonographic demographics on quality of focused cardiac ultrasound
  • Prevalence of ghost scans for trauma patients
  • Development of standards for ultrasound research reporting 
  • Serratus anterior plane block for rib fractures, a randomized trial
  • Increasing EM resident utilization of fascia iliaca nerve block
  • Multiple studies from the National Ultrasound-Guided Nerve (NURVE) Block Registry
  • Racial inequities in POCUS for pregnancy
  • POCUS first for renal colic, a quality improvement study
  • Development of a POCUS protocol for pediatric septic shock
  • Characterizing cardiac POCUS utilization patterns in pediatric sepsis
  • POCUS to distinguish complicated versus uncomplicated pediatric appendicitis 
  • Impact of hallway beds on POCUS utilization 
  • REASON trial - POCUS in Cardiac Arrest 

For more information on our division’s research, educational, and administrative achievements, please read our 2025 Annual Report. 

Fellowship

Brown's Emergency Ultrasound Fellowship is EUFAC credentialed, and our core faculty who qualify completed and passed their FPD AEMUS exam in 2022. At Brown, we offer a clinical ultrasound fellowship that accepts both adult and pediatric emergency medicine applicants and also considers applicants with an interest in POCUS with non-emergency medicine training such as internal medicine or family medicine trained physicians. In addition, we run a non-clinical fellowship that hosts learners from all over the world, who want to come to Brown for a year to learn ultrasound alongside our team. We participate in the NRMP match and look forward to receiving your application and having the opportunity to tell you more about what makes our program so special.
