Resident: See that? That's Morrison's pouch, showing no free fluid between the kidney and liver.
Me: I think that's just static, and you're playing a trick on me. Can we adjust the image?
Resident: No, actually, see, this echogenic area is the renal pelvis...
Me: Really, just stop, you're not fooling anyone.
A few years later, and here I am, identifying venous thrombi and peri-pancreatic stranding, the common bile duct and the superior mesenteric artery. It's unbelievable what you can see in that static-y window. I especially like how, the better I get with ultrasound, the more it seems to help (compare that with sub-subspecialties like toxicology, where the effort of accumulating greater expertise finds diminishing returns for patient aid...)
In my surveys, whenever I apply the ultrasound probe over the male bladder, the men always crack a smile and ask me if they're pregnant. It never gets old. (The women, they don't ask out loud).
There is a striking correlation with EM ultrasound expertise and a past life as a disc jockey. In fact, it turns out I used to listen to one of my U/S mentors, on the radio. Different frequencies now, but same catchy appeal.
