Figure 1 Example of a uniform, blinded polar map consisting of a frame in which areas of jeopardized and nonviable myocardium could be depicted by using a computer. A separate polar map was created for PET results and SPECT results by different physicians. After randomization, only the polar map of the technique which the patient was randomized to receive was presented to the clinicians, who subsequently determined treatment. By using this uniform polar map design, the clinicians were completely unaware whether the polar map showed PET or SPECT results. ANT = anterior; INF = inferior; LAT = lateral; SEP = septal.
