Fig. 6 —Diagram shows comparison of difference between systolic and diastolic myocardial perfusion between ischemia (upper row) and nonischemia (lower row). Numbers indicate mean attenuation value in Hounsfield units as percentage for each segment. Difference between systolic and diastolic myocardial perfusion for ischemia in shaded segments was significantly lower than that for nonischemia (segments 1, 5, 6, 7, 10, 12, 17, p < 0.001; segments 2, 3, 4, 9, 11, 13, 15, p < 0.01).
