How is a venography used to diagnose deep vein thrombosis (DVT)?

ANSWER

During this procedure, the doctor injects a radioactive dye into a vein on the top of your foot before it's taken to help him see your veins and maybe a clot.

It's more accurate than an ultrasound, but there's a slight chance it will cause more blood clots.
