Not in my experience - there tends to be a lot of noise in the data which 
reduces the compression algorithm's efficiency. It is possible to skew the 
greyscale range (i.e. fold several tones into one, just not linearly) in order 
to reduce filesize, but then it requires extra visual checks to make sure that 
important data's not being lost.

This is one area where it's nice that storage is so cheap these days!
