Interesting the various ways they want you to "do" the drink. Locally they have me drink the first bottle 1 hour before the scan, the second bottle 20 minutes later, arrive 20 minutes later at the facility where they greet me w/a glass of water and 20 minutes later the scan is started.
I can't really remember how we did it at Mayo. Arrive at the department, and I can't remember if it was 2 or 3 bottles of the contract or even if we did any water. I just remember it was somewhat different than locally.
I just had one in April and am NOT happy that I have to do another CTE tomorrow, especially since I just had a soft tissue CT scan of the neck on the 8th of this month. Not that I mind the procedure itself - but - between Crohn's and COPD I've had so many radiology procedures I really ought to glow in the dark!! They should have started me out from the get-go and my very first radiology procedure w/one of the badges that rad techs wear to monitor their exposure. I swear I must have had as much exposure as the busiest of them!!!
I will be ever so grateful when they finally perfect the MRE to better, clearer results than the CTE!!! But so far, Mayo told me that the CTE is still superior to the MRE except for the rectal area. *sigh*
At least, assuming we decide to do an FNAB for the thyroid, the needle is guided via ultrasound and NO radiation!!!!
Some people are like Slinkies... Not really good for anything, but they still bring a smile to your face when you push them down a flight of stairs.
