Who am I? My name is Dan Dyar.
Natural Habitat? San Diego, CA.
What makes me qualified to make anything other than passing remarks about pediatric echocardiography? I am RDCS certified in AE/PE/FE; over 15 years experience "scanning".
A 'Fortuitous Concatenation of Shadows'- What is that about? I first heard this from one of my mentors, who picked it up from Baylor. Since then, innumerous others of their progeny have confirmed that the phrase was coined there- as a somewhat pejorative remark about the ambiguity of interpreting ultrasound images.
