That is interesting I never saw it mentioned for gallstones, though I read Shirley's website.
I might check the library for the book, though it may be wishful thinking, $125 for the books is not cheap.
In case you find it before me, may be you can let me know what it says about calcified gallstones. Next year I am planning to have another ultrasound and then will have been on UT for almost 2 years.
