I'm not sure. I would not think that one needs contrast material for detecting colon polyps, but it is hard to believe that one could accurately detect coronary lesions without the contrast. Remember the weakness of the "bare-bones" machine is that it quantitates calcium in an artery but does not tell one how much blockage there is at any one spot. In other words with the same calcium score, one artery could have a 20% build-up along its entire length, but another could have an 18% blockage along most of the length but with a few small areas of 90% blockage. The German studies showing failed angioplasties used contrast.
