That was a big fuckin' donut
I only fell asleep twice; once during the eight-minute scan, and once during the four-minute scan (there were... five altogether, I think. 3, 4, 5, 8, and 4; the first couple were the uncomfortable ones because I had to keep my palm rotated forwards to externally rotate the humerus, and that gets tiring). I have a CD with my imaging results on it, so I will be checking those out on my home machine tonight (no optical drive on my netbook), and the evaluation will be transmitted to my orthopedic dude once it's been conducted by the radiologist or whatever the imaging expert's title happens to be.
I am a sexy bitch in hospital scrubs, I tell you what.
