In this practical introduction to FLASH (Focused Abdominal Sonography for Horses) ultrasound, you’ll learn when ultrasound can be useful in the evaluation of equine colic and how to approach a systematic abdominal examination using the FLASH protocol.

This course provides an overview of the use of abdominal ultrasound in the evaluation of equine colic patients. Participants will review indications and clinical considerations for performing colic ultrasound, foundational ultrasound principles, and the FLASH (Focused Abdominal Sonography for Horses) protocol. The course will review the seven basic ultrasound windows included in the FLASH protocol and use examples of normal and abnormal sonographic findings to illustrate their clinical application in the assessment of equine colic patients.
