Have to go for a CT scan next week and will have to drink something called gastrografin beforehand. I understand that this is a radioactive compound and halps to make the contrast in the X-rays sharper. I have to start taking it the day before the scan.
The Gastrographin we use smells like aniseed, and the patients I give it to tell me it dosn't have a taste to it, I haven't offered to try it for them so I will have to believe them. We only give it about 60 -90 mins before the proceedure tho. It is supposed to make what they are CT ing stand out a bit clearer than it would without the contrast medium.
Margaret - the instructions they've sent me tell me to take half of of the night before and the other half two hours before. It's 100ml, to be diluted in water or juice.
I've also now discovered that it contrasts the soft tissues much more clearly and, as they want to examine my pancreas, gall bladder and connecting ducts, I guess that makes sense, They've already seen the huge amounts of gallstones on an ultrasound.
I guess it must be safe and not have any side effects or else they wouldn't have sent it to me to take at home before I go! Says she, hopefully
That's ok Kofi, take as they have instructed. The stuff we give is more concentrated and if they want to look at all the duct it may be to see if any of the stones have moved from the gall bladder itself into the duct causing blockage, narrowing or unlikely complete obstruction. You'd know it if that were the case. They may also be able to decide whether to remove the stones without a cutting open operation. Best wishes.
