I did this test just a few days ago.
I did not have any shot or medicine to stop my bowels. My instructions were to stop eating/drinking 6 hours before the test. I went in and they hooked up an IV, drew blood via the IV to test my kidney function because they use some sort of contrast for the test via the IV, and the contrast is excreted via the kidneys. I then drank 6 cups of Volumen, which is a sweet liquid, not quite as thick and gooey as honey but it's not a typical liquid like water would be. It's sweetened with Xylitol, not sugar, so no worries about overdosing on sugar.
It was really easy. Lied on my stomach, went into the machine feet-first. This was perfect for me because I never even saw the inside of the tube from this position (I'm really claustrophobic and was a bit nervous). Hold your breath about 10 times for 10-15 seconds while they do the scans, then they inject the contrast & do 7 more times. Took 10-15 minutes to do the scans.
I was concerned that the gooey Volumen stuff would hose up my guts and make me feel ill or super-diarhea-ey, but it didn't do anything negative to my guts. Actually I felt better after drinking it, and wondered if the ingredient have some sort of ameliorating affect. (I felt the same way when I drank gastrografin for CT scan a few years ago).
The contrast is not the horrid gadolineum (sp?) or whatever that is used for CT scans, thank goodness. Just a slight sensation of having a penny in your mouth (copper taste). No biggie.
I would do the test again in a heartbeat if necessary. There is no radiation, unlike CT scans. I won't do CT scans any longer, I've already done 4 or 5, and was reading recently how they emit a great deal of radiation and the doctors prescribe them too frequently and nobody keeps track of how many CT scans each patient has had in their lifetime. We all should keep track of our CT scans and not let them be done unless truly necessary. My doc's have all raved about the MRI Enterography test as being a really super test, cutting-edge with good views and no radiation.
