Thanks ** for a reply.
I have also had many MRI's done before (10) and have never had any issues with heat. One time I did come out bright red but that faded after a few hours but it was not related to heat.
I decided to investigate today and went straight to the horses' mouth, who happens to be my sister. She is lead scientist at a Magnetic Resonance centre.
This is what I am told... MRI uses electromagnetic energy and pulses of RF (radio frequency) to create the images. All fairly complex but it involves RF signal close to those of microwaves. The magnetism is about 25 000 times stronger than the earths magnetic field. The RF pulses are specific to hydrogen atoms in our body and it moves those around and via the coils and receivers in the MRI machine they are translated into images. (Hope I got that right...similiar idea even if not totally correct)
Although rare she told me you can get burns from the machine if the conditions are right (happens to not feel right though!
) The concentration of electrical current can cause burns and tissue damage.
There should never be any direct contact between your skin and the body of the machine and it is meant to have some padding there if you are likely to touch it. The transmit RF coil(that sends the pulses) is right behind the tunnel.
You should not have parts of your body touching each other where they can form a closed loop.
Plus certain medical leads,some surgical clips/pins etc and patches can be conductive and cause burns.
I had no medical equipment nor patches but had two of the other options. They put me in the scanner with my arms on top of my chest with my hands folded and I also had both elbows touching the the body of the machine. I guess a recipe for the outcome I have. I believe what I have is an RF burn which would explain why there is very little visible on the outside. Does this mean my inner bits at the elbows are nice and tenderly cooked then?
I definitely do not have any metal in my arms so we can rule that one out. The scan was actually on my back and totally unrelated to the arm problems. Arm surgery is for nerve damage to elbow.
I guess it was inattentiveness or lack of knowledge on the technicians part that this happened plus the fact that I had sedation and was too dopey to realise what was happening. I couldn't possibly go back to the centre and say anything because they are the one and only company that do medical imaging in practically the whole of the state I live in. I do not want to get on their bad side that's for sure. I did however write to the director of the company telling him to get his staff to get their crap together because if it was an elderly person or a child it would be very serious. I hope they take the advice and save someone else the pain of it.
So I am still no closer to finding out how long it will take to heal but am more knowledgeable for the experience I guess.
Sis also told me that none of them are stupid enough to get a burn to find out healing times and side effects etc so she can't help on that part of it. Don't blame them because it isn't overly pleasant and so far it is not improving. Oh, I did mention it to the tech after the scan that my arms were burning and she laughed and said "oh
did it get a little hot?" end of conversation as she walked away. No interest and as though it was common there.
Anyway, thanks for your input. It is appreciated.
