Figure 2: (a) TFE-DW 3T MR image in the axial plane showing the lesion (L) as a hypointense structure splaying the hyperintense right atrium (RA) and right ventricle (RV). (b) T1-weighted FSE of the heart in the axial plane showing the heterogenously hyperintense lesion (L) with internal septae within involving the anterior mediastinal region, centered on the atrioventricular groove between the right atrium (RA) and right ventricle (RV), with the right coronary artery (RCA) seen passing inside the lesion appearing as a signal void vessel. (c) T2-weighted TSE-BB 3T MR image of the heart showing the hyperintense lesion (L) abutting the right atrium (RA) and right ventricle (RV) which display a hypointense signal. The heterogenous intermediate-to-bright signal of the pericardial effusion (P) is seen at the right lateral aspect of the lesion
