MRI Scan

I had my MRI scan with Vista Diagnostics just outside Waterloo Station, London (www.vistadiagnostics.co.uk). By this time my symptoms were 80% resolved but being a chiropractor I was aware of the feeling of low back instability and knew something wasn’t right.

How Does an MRI Scan Work?

MRI stands for Magnetic Resonance Imaging. There is no ionizing radiation (the type from an x-ray, or from flying or watching TV). Radio waves are 10,000 to 30,000 times stronger than the magnetic field of the earth are sent through your body. This affects the body’s hydrogen atoms (those found in water), forcing the nuclei into a different position (flipping them). As they move back into place they send out energy in the form of radio waves. The scanner picks up these signals and a computer turns them into a picture.

Mri Claustrophobia

First of all I recommend that you bring your own ear plugs as I wasn’t offered any by Vista Diagnostics. I think this is poor. I had no idea just how loud the machine was going to be (some MRI scan labs offer you head phones with music). Think night club base mixed with slow pounding jack hammer on the pavement. This is far more stressful than having to stay still or going into a tube. If you are having a spine MRI (for your low back)  then you really don’t go into the tube all that far. My legs were sticking out from about the knee down. I kept thinking stupid thoughts like what if someone tickles my feet? It is a great idea to close your eyes as soon as you lie on your back before you start going into the tube. Don’t open your eyes to look at your confined space (this made claustrophobia a non-issue for me).

Drink bottled water after your MRI scan. There is no official stance on water drinking after an MRI scan. It just makes sense that if you are playing around with your hydrogen ions  you might just want a top up supply!

Are MRI Scans Safe?

This is what I think. There is no way that having a magnet 30000 times the pull of the earth flipping your hydrogen ions around is completely desirable. We may not ‘feel’ it is doing anything but anyone sensible knows that many health problems come without any symptoms. I am not saying don’t have an MRI. You have to weigh-up the benefits and risks. We know the benefits but I am just not convinced if we know the possible risks. They don’t let pregnant women have an MRI scan and when I asked the radiographer at Vista Diagnostics why not, she said ‘because we just don’t know the possible effects, although we are quite sure it is safe.’My body got very hot during my MRI scan. I am not talking a little warm all over, or a bit stuffy but my back was hot as if lying on a hot plate just starting to heat up. I assumes this was from the energy released from my body during the hydrogen ion flipping. I also experienced fasciculations (muscle twitching) in my triceps and latissimus dorsi muscles. I couldn’t control them. I just kept thinking damn, I am not suppose to move. It lasted about 60 seconds. I have googled a few other opinions on MRI scan side effects:

  • I recently had an MRI, this is the third or fourth, any time I go though the anti-theft devices at stores. The alarm sounds when I have nothing on me.
  • Submitted by tania (not verified) on Wed, 11/01/2006 – 11:16am. My husband also had a similar situation as yours with horrible headaches following the MRI, please let me know what u found out
  • I had an MRI for my hand injury about 3 yrs ago and after that the first night in my bed I was hearing buzzing and ringing in my ears. The sound have been subsiding until 3 weeks ago which has become worse. Could that be a side effect due to that MRI?
  • I had my first MRI of my brain yesterday and I felt very weird, spaced out, and VERY tired and got a terrible migraine afterwards. I had earplugs in, but they didn’t help a whole lot. While I was in the MRI I felt pressure on my forehead and it also felt like an energy swirling in the middle of my forehead. VERY uncomfortable. I still feel like crap today.

So there you have it. I still wouldn’t hesitate to have an MRI, but I also strongly believe that the only ‘safe’ medical procedure is no medical procedure!

Keep the comments coming. This type of open discussion might just pave the way for future research!
