I think it would have to use a constant scan to recover parameters passed in the statements. I'd suggest you use profiler to capture the query plan, rather than QA, although the detail is overwhelming you may find it more useful. I generally use QA to produce plans but if I'm really trying to find something I always use profiler. Make sure you include the binary data column in profiler.
