It [being busted] happened to me a long time ago ...not wearing Toplace at the time..... it was at a Chinese acupuncturists .... I was having bad sinus inflammation etc. [ have since cut out dairy products and the relief is tremendous.... goats cheese and milk for me now !! ] but the person was putting needles in around the sides/bridges of the nose and when they went to put ones in the crown of the head, naturally enough they realised there was `something` there.... so I guess you`re juts better off mentioning it first if you think a person `working`on you at such close quarters may suddenly say `what`s that`? ...... but I think the original question here was would a system interfere in some way with a scan like an MRI ..no it won`t.
