How to see all orphaned/top-level work items?

I want to run a query to show me every work item that has no parent, i.e. all my team's top-level work items/stories (we are using the Scrum process).
I can produce a query of 'parent exists', but I can't find a 'parent does not exist' or any way of doing something like 'NOT parent exists'.
Any suggestions?
Thanks,
Brian
