Figure 1 Examples of dipyridamole positron emission tomography with improved perfusion indicating regression (A) and with worsening perfusion indicating progression of coronary artery disease (B). Three-dimensional topographic views from left to right are lateral (Lat), inferior (Inf), septal (Sep), and anterior (Ant) views. The upper row is after dipyridamole at baseline, and the lower row is after dipyridamole at follow-up. Resting perfusion images were normal (not shown). Red = the highest flow; yellow = intermediate; green and blue = progressively lower perfusion in continuous graded steps according to the color bar.
