The tech did not introduce himself to me or my child.  He didn't explain how anything would go.  He left us in the changing room for 20 minutes with no explanation of why.  When scanning, he didn't talk to us.  He didn't offer me a chair and the exam was almost an hour.  I'm not sure why a tech like this is working at a children's hospital. He made a joke about guns and knives.  He said it was annoying to have to change the equipment during her exam He didn't explain what to do when our exam was over.  I asked how to get her results and he didn't know.  It was a very disappointing visit.  I would mention his name but he didn't have a badge on or tell us what his name was.
