I went in for my parathyroid scan, which involved an injection, several scans by one machine and an hour long scan by another machine and then waiting an hour to get scanned by the first machine again. Somehow, out of all of those scans, the results were inconclusive! How can that be???? Anyway, the doctor wants me to have a "2 day scan" now. All I was told was that I would come in on day 1 swallow a pill, leave, and come back on day two for a scan. What do you think they are looking for? The tech did blurt out to me that they found "something", but it was "as small as a grain of rice". I don't think they are even supposed to say anything, but the scan was done in a hospital, so maybe they are allowed to discuss results there?
