> Dear Colleagues,
> We're using a SPGR fat suppressed sequence to image human articular
> cartilage in-vitro. I'm inquiring about alternative materials (other than
> fluid filled bodies, such as VitE capsules) which are suitable for MRI
> phantoms. Ideally, I'd like to find a material that can be poured into a
> mold and which hardens over a short period of time with negligable
> shrinkage, and would like to have compounds which image high intensity
> (white) and very low intensity (black). I'd like to use the low intensity
> compound to provide high contrast against the superficial surface of
> articular cartilage, and therefore the molecular makeup of the compound
> must be such that it will not be absorbed by the cartilage. Does anyone
> have experience with, or know of, any such materials?
> Thanks in advance!
