I went to Lexington Diagnostic Center to get a bone scan. From the time of arrival till the time I left, I felt like I was treated very well. After I was injected, I had to come back 3-4 hours later. Once I came back the process was simple and painless. I have had a bone scan before and it seemed to take forever; the person did not seem to know what they were doing. This was not the case here. For haveing a bone scan done, I would say that it was pretty harmless.
