Hi I am having an MRI done this morning on my abdomen. I have had one on my knee lasted 10 minutes then pressed the emergency button, I had the Same scan done 7 years ago but the first time I ran away second time I had it done on 10mg lorezapam and it was fine no recollection but I lost the whole day. I a having it done today without sedation because I've got something on this afternoon. It is an open scanner does that make a difference.
