Figure 2 Short-axis cardiac magnetic resonance images of the same anatomical regions with pathological findings in a patient with acute myocarditis. (Upper row, left) Steady-state free precession images in diastole (left) and systole (right), showing anterior hypokinesis (arrow) and a small pericardial effusion. (Upper row, right) Triple-inversion-recovery prepared T2-weighted spin echo image showing regional edema of the anteroseptal, anterior, anterolateral, and inferior segments with predominant subepicardial involvement. (Lower row, left) T1-weighted fast spin echo images before (left) and after (right) application of gadolinium. Note the diffuse signal intensity increase. The quantitative evaluation showed a pathological signal change. (Lower row, right) T1-weighted inversion-recovery prepared gradient echo image obtained 5 min after application of gadolinium. There are extensive areas with high signal intensity (late enhancement), predominantly involving subepicardial regions (arrows). A small artifact is noted, which should not be interpreted as pathology.
