A review is given of 95 publications on OPG-Gee and OPG-Kartchner in order to compare both techniques and to determine the present value and perspectives. Both techniques are valuable in the evaluation of the hemodynamic significance of carotid lesions, but OPG-G has a better sensitivity than OPG-K. Specificities are comparable. OPG has delivered new knowledge on the natural history of carotid disease, pre- as well as postoperatively and is helpful in recognizing stroke-prone patients. It provides in a simple way useful physiologic information.
