Hi Tim:

    Any processing will induce some shrinkage so my first suggestion is 
to measure fresh or fixed tissue with a dissecting microscope. If that 
is not possible I suggest a thorough fixation in formalin or 
formalin+glutaraldehyde followed by embedding in an epoxy resin (Epon 
substitute). Much less shrinkage in epoxies as compared to wax or 
methacrylates.
