Figure 2 The diagnostic performance of TI-scout images is superior to PSIR image in patient with subendocardial LGE TI scout images shows LGE of subendocardial myocardium reaches the null point (red square, arrow) earlier than the blood pool (blue square); PSIR image shows that the subendocardial LGE and the blood pool are poorly demarcated, which is likely to cause a “false negative” diagnosis
Figure 3 The diagnostic performance of TI-scout images and PSIR images are complementary in patients with focal patchy LGE TI scout images shows myocardium of the inferolateral wall of the left ventricle reaches the null point (red square, arrow) earlier than the blood pool (blue square), similar to suspicious LGE on short-axis PSIR
Figure 4 The diagnostic performance of TI-scout images are superior to axial PSIR image in patient with transmural LGE TI-scout images shows the transmural LGE, the myocardium reaches the null point (red square), earlier than the blood pool (blue square), however, the short-axis PSIR image only shows the subendocardial LGE, which underestimates the extent and severity of the lesioned myocardium
