So, I got my MRI pictures back – including the DTI. This is my latest thing – looking through the pictures to see what I can see, and also compare my brain to how it was back in 2009, when I had my first MRI (for the seizure-like experiences).
I have yet to find out what they all mean, but one of my nagging concerns has subsided. I was worried that they would not find anything to explain my dizziness and other symptoms. But apparently, there are some ROIs (regions of interest) on my pictures (they are outlined in the picture above), and there are some apparent differences between the two sides of my brain.
Overall, the radiologist’s report came back looking quite good. At least, as far as I can tell… who knows what it really means? I’ll find out next Tuesday — less than a week, now — when I meet with them again and they have all my data in hand and have done the analysis.
The other thing I’m digging into is the DTI tractography, where you can see the actual connections between the different parts of the brain. I need a better viewer, because the one I have is 2D. I need a 3D viewer. But to do that, I need to have a more powerful computer, because this old clunker is still running Windows XP, from 2002. So, it’s time for an upgrade. It’s stood me in good stead, but it’s no good for doing modern work — like properly sized videos, as well as complex 3D rendering.
The new 3D viewers available today (some of them are actually free) are pretty amazing. If you have a modern computer (with Windows 7, at least, or possibly a Mac), you can see some amazing things. For free. There are also datasets you can download to view and play with. I have done a little bit of that, but again, my computer hasn’t been strong enough to keep up.
So, I went on eBay and found myself a better computer — for a fraction of what it would normally cost. I know what to look for, and I know how to select the stuff that will serve me best, so I can get a really great deal. This computer has lasted nearly 10 years, and it cost me a little over $200, so I’d say it’s been a good value.
I hope the same is true of the next one I get.
Anyway, I’ll be researching DTI MRIs as my new hobby. Radiology has always fascinated me, and the 3D technologies we have now are nothing short of amazing. It’s a great way to pass the time — you learn a lot, and it’s all very real stuff.
