I've wanted to discuss tips and pitfalls for the FAST exam for a while now, but I needed a master to talk with. Luckily at Castlefest, I met Laleh Gharahbaghian, MD. She is the Ultrasound Director at Stanford's Dept. of Emergency Medicine as well as being too cool for school. She is also FOAMY with what I think is the best blog on all things point-of-care ultrasound: sonospot.com.
