CT vs. MRI…

Over at CancerCompass, I sat in on  a recent discussion of unwanted radiation exposure from X-rays and CAT scans. The topic was, of course, how many scans have you had since treatment ended, how soon after treatment ended, and what types of scans did you have. As for me, I had my first scan about 3 months after ending radiation therapy and was told that often some false positives might show up due to inflammation. It wasn’t the case immediately although I had a few scares about 2 years down the road.

The discussion also raised some questions about what types of scans are used and why and exactly what are the benefits and the risks. With a bit of research, I found an easily understood side-by-side chart of CT Scan vs. MRI, what the comparative radiation exposure was, what they’re used for, and what they detail.

There are also several other comparisons to jump to including CT  vs. PET, MRI vs. X-ray, etc.

And then there’s still the interpretation…

Worth a view…never mind the addies…the net is really just one huge marketplace…
