Many of us girls have been so lucky as to undergo transvaginal ultrasound, or what some folks call "gettin' speared with the cooter wand."
The project I'm editing right now pertains to urology, and I just learned about a test doctors do for fellas with prostate trouble: rectal ultrasound, in which the cooter wand becomes a heinie wand. (Yikes!)
Urologists have many tricks up their collective sleeve. They've concocted voiding cystography as well, in which the patient is injected with a contrast dye and then basically x-rayed WHILE PEEING.
Although that's nothing compared to what I read about back in the day when I handled a book on gastrointestinal radiology: defecography. It's a lot like voiding cystography, but with #2 instead of #1. (I will never forget the key piece of equipment: "a radiolucent commode." That steel toilet's just gonna hide the action; better to go with plastic.)
