Re: How do they check your gall bladder???
No water drinking needed for an ultrasound of the gallbladder. Follow your doctor's instructions.
The ultrasound is very easy. You just lay there in the dark room and the tech puts gel on your stomach and moves this wand around and looks at the computer screen. Occassionally you have to take a breath and hold it so they can take a picture. Takes maybe 20 minutes.
The hida scan is also easy. You do need to get an IV put in, but that's the worst part. After that, you just lay there. If you have one, take your mp3 player to ward of boredom! They inject a small amount of a radioactive tracer through the IV. This gets picked up in the liver and put into bile, which goes into the gallbladder. They lay you on this skinny table and slide you into this ring-like machine (like a cat scan) that picks up the signals from the tracer. Over the next hour or so, they watch the tracer go through your liver and fill your gallbladder. When your gallbladder is full of bile, they inject a synthetic hormone (CCK) into the IV. This is the hormone that is released by the body when you eat a fatty meal. It causes your gallbladder to contract and squeeze the bile into the small intestine. So they watch to see how much of the tracer is squeezed out, thus getting a measure of function. The hida scan can take up to two hours, so it's not a bad test, just boring.
