Figure 3 Discrepancy between MSCT and MPI. Example of a 69-year-old man with an abnormal MSCT but no perfusion abnormalities on MPI. In A, C, and D, curved multiplanar MSCT reconstructions of, respectively, the left anterior descending coronary artery, the left circumflex coronary artery, and the right coronary artery are provided. B is an enlargement of the proximal part of the left anterior descending coronary artery perpendicular to A, whereas a 3-dimensional volume rendered reconstruction is provided in E. In all 3 coronary arteries, the presence of diffuse atherosclerosis can be observed. In F, however, short-axis (upper two rows), vertical long-axis (middle two rows), and horizontal long-axis (lower two rows) myocardial perfusion imaging during exercise (first, third, and fifth rows) and rest (second, fourth, and sixth rows) demonstrate homogeneous myocardial perfusion without perfusion defects. Abbreviations as in Figure 1.
