In my experience the extremely (sometimes I can't even tell) slight
posterior difference in resolution is far outweighed by the deeper scan
penetration. I would probably do all my HD scanning in EDI if I was in
clinic daily, and thats what I recommend at most of the bigger sites I
visit. Maybe occasionally not using it for things like ERM's and VMT, but
those still show up very well in most cases using EDI.
