  Figure 1. The procedure of “DE normalize contrast” (indicated by arrows) in the iodine map on dual energy computed tomography using a dedicated workstation. DE, dual energy.

  Figure 2. Nodular transmural involvement of acute myocarditis. The dark areas on the iodine map on the dual energy computed tomography image (thin arrows), the corresponding edema on the T2-weighted image (thick arrows), and hyperenhancement on the late gadolinium enhancement image (in the circle) in the cardiac magnetic resonance image.

  Figure 3. Band-like intramyocardial involvement of acute myocarditis. The dark areas on the iodine map on the dual energy computed tomography image (long arrows), the corresponding edema on T2-weighted image (short arrows), and hyperenhancement on the late gadolinium enhancement image (in the circle with arrows) in the cardiac magnetic resonance image. The arrows indicate the band-like intramyocardial involvement of acute myocarditis.

  Figure 4. Band-like subepicardial involvement of the lateral wall and nodular intramyocardial involvement of the septum of the left ventricle in acute myocarditis. The dark areas on the iodine map on the dual energy computed tomography (DECT) image (single long arrow), the corresponding edema on the T2-weighted image (double short arrow), and hyperenhancement on the late gadolinium enhancement (LGE) image (in the dark circle with arrows) in the cardiac magnetic resonance image (CMR) for nodular intramyocardial involvement of the septum of the left ventricle. The dark areas on the iodine map on the DECT image (multiple long arrows), the corresponding edema on the T2-weighted image (multiple short arrows), and hyperenhancement on the LGE image (in the white circle with arrows) in CMR for band-like subepicardial involvement of the lateral wall.
