Turn on RSS via ctl and query the following columns from ResUsageSvpr table

     FileSyncScans
     FileSyncSubtables
     FileSyncScanners
     FileSyncGroups.

If you try this on a quite system, it's easy to figure out whether a given query uses SyncScan.

If you try this on a production or busy system, it will be hard to pin down which queries uses syncScan and you can only get an idea how many syncScans occurs during a particular time.
