ability to undergo imaging.

3. Patient weighs over 350 lbs (due to scanner weight limit).

4. Clinical life expectancy < 12 weeks.

5. Participated in other radioactive drug studies where estimated total cumulative dose
within 1 year is > 0.05 Sievert for whole body, active blood-forming organs, eye
lens, gonads, or 0.15 Sievert for other organs.

6. Concurrent Therapy. Allowed: Prior or concurrent chemotherapy, but must be > 12 weeks
since last treatment at enrollment; prior or concurrent hormonal therapy; prior
surgery; prior or concurrent bisphosphonate; prior or concurrent receptor/biologic
agent allowed if given on study protocol (e.g., SWOG S0421: Addition of atrasentan to
