Emergency Medicine Ultrasound

In emergency medicine, timing is critical, especially when lives are at stake. Ultrasound has been called a "superpower" in the race against time because it enables physicians to rapidly diagnose and manage disease. Bedside ultrasound is rapid, portable, repeatable, noninvasive, and avoids radiation. 

Consistent and skilled application of bedside ultrasound has been shown to increase patient satisfaction, decrease length of stay, aid in patient flow, lower healthcare cost, and, most importantly, save lives.

The growth of ultrasound applications has opened up new possibilities for ambulatory, critical care and emergency physicians. Stanford has been at the forefront of this new frontier, driving research, discovery, innovation, and educating physicians locally and internationally.
