- I've seen MRI scans of a patient with severe sinus infection, and we were
- able to take the images & do a 3D rotation scheme and see exactly where the
- infection/swelling was. The inflamed area showed up as a very bright
- area, with the air passage being black (no signal from air). It turned out
- that one side was fine, the other was badly infected with about a 5mm diameter
- passage for the air, max.
-
- MRI scans can be 'tuned' to look for different things, and different types
- of contrast. Write me if you'd like more details. I'm not an applications
- person (with direct patient contact), but I'm on the technical side of the
- fence, and have access to a lot of information.
