The drink (barium sulfate) is to coat your GI tract (stomach,small bowel, large bowel) to help differentiate between them and other organs. It will help distinguish any other possible abnormalities in the abdomen.
The dye enhances your venous and arterial (depending on the study) system. This will highlight mostly blood vessels outside and inside your organs.
do lymph nodes show on a cat scan
They are just as they say. An abdominal cat scan is just of that area and a pelvic cat scan is just of that area. Usually if an abdominal cat scan is ordered a pelvis is included so as to cover all things in both areas but if a pelvic cat scan is ordered it usually does not include the abdomen.
You do not have to stay home after a CAT scan. The procedure has no residual effects. After you leave the clinic or hospital, you can resume normal activities if you are otherwise healthy.

Yeah, a cat scan is pretty much safe. I say 'pretty much' because the ionizing rays cat scans apply can cause DNA which can lead to cancer. Same as X-rays. However, this is very rare, and your doctor would only give you a cat scan/X-ray if he thought you really needed one. What I'm saying here is that, for all practical purposes, cat scans are safe.
