Hi Everyone, I had my Gastric Band procedure in 2007. All good, no problems. Life changing !! xxx But other health problems mean that I have to have a MRI Scan - which the hospital won't/can't do because they need a couple of pieces of information. My band is an early type Swedich Band, an OBTECH GASTRIC BAND. S/N - 200804 I am trying to locate the following 2 pieces of information :- 1. SPACIAL GRADIENT FIELD 2. STATIC MAGNETIC FIELD I would be thrilled if anyone can help with this - or point me in the right direction to acquire this info. Fingers crossed that someone may be able to help, Many Thanks, Graham
