I had this done yesterday at my hospital. I had the four hour nuclear scan. I ate some egg whites after fasting for 12 hours. They rearranged the time so I could start at 12 pm because I'm nocturnal fortunately.
Then I was scanned while standing in front of a flat panel machine- the first one right after eating, then every hour for two hours and then the last one 2 hours later.
It was pretty hard because I wasn't allowed to eat of course and I was pretty hungry towards the end, fortunately my bg didn't crash and stayed at 150's-160's the whole time. I was afraid to correct it lower in case of lows. I was allowed to drink two glasses of water , one with the egg whites and one later and they said some juice/glucose tabs was ok in case of lows.
When I ate the egg whites I had to wear gloves to avoid contaminating things with radiation. The tech also gave me a label saying I had the test done in case the radiation set off any scanners! I have to say even though I know this is very low dose this made me nervous. I was even going to cancel the test when I woke up, but my father convinced me it is completely safe, it's very low dose and will not cause cancer etc.
I don't have my results yet, they should be online tomorrow. I'm just wondering how accurate this test is? I have IBS and my digestive issues vary a lot from very bad to more normal with constipation/runs etc.
Since right before I was in the hospital things are much worse though and I have noticed I have bloating now when I eat and feel very full with some stomach pain and nausea. I had that last night especially after my dinner and I wonder if that is from the test/radiation? I was constipated the whole day pretty much and then for about 24 hours until today so that probably means the radiation stayed in me longer. When I ate the egg whites I did feel that they went through my system but I guess it's hard to tell for sure. I noticed a slight rise in bg but I had also turned off my basal for 2 15 minute periods due to feeling I was going to crash.
I'm wondering if this will accurately diagnose any problems because it can vary so much from day to day. I'm kind of dubious about the whole thing- I read some people's comments last night that they have had different scans where the result was normal on one and abnormal on another.
