(A) Axial plane black blood turbo spin echo T1-weighted cardiac magnetic resonance imaging, tumour shows an intermediated signal. (B) Axial plane, black blood turbo spin echo T2-weighted spectral attenuated inversion recovery that suppresses fat, tumour shows a high signal, indicating a lack of fat content. (C–E) Axial, sagittal, and coronal plane of mDixon water reconstruction T1-weighted three-dimensional non-contrast-enhanced magnetic resonance angiography with respiratory navigator gating, showing an intermediate tumour signal. (F–H) Axial, sagittal, and coronal plane of mDixon fat reconstruction T1-weighted three-dimensional non-contrast-enhanced magnetic resonance angiography with respiratory navigation gating, indicating the absence of fatty content in the tumour. (I) Axial plane of the perfusion image in which contrast appears in the tumour in the late arterial phase. (J) Axial plane of the cine TRA bTEE and (K–M) axial, sagittal, and coronal plane show the absence of late gadolinium enhancement. The white arrow points to the tumour in all panels. Ao, aorta; bTEE, balanced turbo field echo; LA, left atrium; LV, left ventricle; PA, pulmonary artery; TRA, transverse.
