I was at the hospital for a lung CT which I have done annually at St. Lukes.  Upon checking in at the Imaging Center the girl insisted that I needed to take my bra off. I  told her I had a sports bra on with no metal at all, just material, and that I have this done annually and never needed to remove my sport bra before and she insisted that I need to.  When I entered the scan room and I asked the tech about the sport bra she said it was not necessary to remove it for the scan.   I know I would appreciate it, and I am sure other women would, if the people that check patients in would be considerate of the patients opinion and be aware of what needs to be done for a procedure and not keep insisting they are right.
