To get admitted into a PhD program directly without MS, requires some research experience in the field(if you want admission to a good, competitive program). A really good GRE score might help substitute this factor but not always. An alternative to that may be, take admission in the MS program and then switch it to PhD after a semester or two. But you should join some research lab right in the beginning of your MS, in your to be successful in changing the program. Hope this helps.
