Hi Cherie,
This was posted in MSWorld some time ago, and I responded to it there. Cutting to the chase: this isn't a new concept, actually - studies with proton relaxation MRI were done in the early-mid 90's. Newer pulse sequences make the technique more viable today, but remember - this is a single investigational study with a very small test group, and the conclusions reached are those of the researchers who conducted the study. Their conclusions are subject to discussion and varying degrees of acceptance or rejection from other imaging industry professionals. Still, it's interesting theory.
