fMRI - Moved Up to Tomorrow - 9/29/08
MRI, Brain Tumor No Comments »My next scan was originally scheduled for October 6th but I have experienced a few focal seizures over the past several weeks that have made us decide to move this up and take a look now. The last seizure wasn’t real severe but was enough that I took some additional meds to put it away. This time we are doing something different, too.
The type of imaging study that is being performed this time is an fMRI, or Functional MRI. Subjects participating in a fMRI study are asked to lie still and are usually restrained with soft pads to prevent small motions from disturbing measurements. This really isn’t any different from a standard MRI - you’re always given pads around your head and arms. Anyway, the primary difference with an fMRI study as compared to a standard MRI (both can last 1-2 hours - how fun to be in a “tube” that long, huh!) is subjects may view movies, hear sounds, smell odors, perform cognitive tasks such as memorization or imagination or in my case, press a few buttons and perform other motor function tasks using my left-side (recall I have a right-frontal brain tumor - deficits are contralateral so we want to see impact to the left side).
So, put simply without getting into a lot of scientific jargon, the goal of this is to “map” more or less the areas in and around the tumor that are directly affecting certain motor functions (the movement of my left shoulder, or knee, or fingers for example). When we know that, we can determine what areas of the tumor could be relatively safe to debulk with limited neurological deficits - at least in theory. Nothing is without risk. After all, this is brain surgery. So, we’re aren’t preparing for surgery here at all but given the seizures we need to see what is going on. We’ve been watching it every 60 days so this time we just moved it up a bit - no big deal.
Here is a picture of an fMRI machine to give you an idea of the environment. Again, getting tubed an hour or two (and sitting absolutley still) is a chore, but I have done ok with it so the technicians have said.
And guess what? I can’t do anything about what is going on, can I? Nope. I pray for the best outcome. We know that God is in the middle of our lives - Rachael, Aidan (6) and Keegan (1). It’s certainly hard not to let physical symptoms get to you - I won’t lie. But when they do, you just have to keep rolling along.
I’ll post results here when I can. As I mentioned before - the lack of posts means I’m doing good! I’m enjoying life. Soccer has been a blast with Aidan. Being involved, running around a field in soccer clothes (I used to play competitively) and playing with him and all of his team, helping with the coaching and teaching the kids - what a great experience and just a few months ago I was on chemotherapy.
More in a day or two….
