Mine is also on the 18th! I have an elective on the 1st, but the one on the 18th is with my doctor so I'll give their answer a big more merit then the one I will get next week!
They won't even schedule mine until March. I guess the appointments don't go that far out in the radiology department. It will most likely be the week of the 23rd.
