Addendum
Just to follow up, what I described are two separate phenomena. For lesion counting, the use of thin sections probably increases your count, only because you will likely see the same lesion on two slices if they're thin enough. Since more and more patients seem to be seeking out 3 tesla scanners - which may use thinner sections - the problem is only getting worse.
Patial volume averaging is more likely to obscure the presence of a small lesion, and this is where thin sections are helpful.
