Well, in the end,the MRI didn’t go ahead tonight.
In 2001 I had a Laparoscopic Cholecystomy which to the layman means I had my Gall Bladder removed using key-hole surgery. Because they needed to check that the ‘plumbing’ to my pancreas was clear before they let me home from hospital, they left a little tube in place – through the skin, secured by a metal clip. The day after the surgery they used a fluoroscope (think live x-ray) and injected some dye into the tube to make sure that the ducts were clear. This was fine, so they removed the tube, but the clip remained.
Now, as you probably know, MRI scanners use the most powerful magnets on earth and the scanner that I was due to be scanned in this evening was even more powerful than the scanner at the hospital I was last scanned at to look at my pancreas (3 Tesla compared to 1.5 Tesla). This scan was taken after the surgery and I had no problems with the clip. However, since this scanner was at a research facility and without medical backup, they didn’t want to take the risk.
Anyway, tomorrow they will call their radiographer and ask his/her opinion as to weather they should take the risk of scanning me. I have also said I will phone the surgeon who put the clip in to ask him what type of metal it is. If they know that, then they can be more sure of the risks – not all metals are attracted to magnets!
So maybe tomorrow I will get what I came for!
Good night and good luck!
