With a change of machines the protocols were revamped and we are now using sequential 5 mm thick slices all the way through.

One of my colleagues has complained about this change, stating that lesion conspicuity will be reduced by using thinner slices above the tent. I personally prefer the uniform and thinner slice thickness but cannot find anything in the literature to support either argument – there is lots about acquiring as thinly as possible in the posterior fossa but nothing regarding the optimum slice thickness for the cerebral hemispheres.

Can anybody help?

This would be a great place from members to share protocols, and open a discussion about the best imaging techniques.
