Tank Sherman 0 Posted June 26, 2017 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 Share this post Link to post Share on other sites
