I follow Dr. Micheal Davis' blog, and he prefers the NMR version.
The Heart Scan Blog: Lipoprotein testing
I just found out that our local hospital now has a new 64 slice CT scanner and does calcium scoring for $50 cash. Woo -hoo. Now I can find out if I really have heart issues creeping up on me, or not, instead of all the supposed "risk factors" (just take some statins....etc.) There is no way they can be making a profit on this. I wonder what the motivation is for the investment. (I have my suspicions)
The Iranians are missing a plausable excuse. "The ultractrifuges are just for cholesterol testing to prevent heart disease!!"
