Calcified constrictive pericarditis, axial T1-weighted spin-echo CMR before (a) and after (b) administration of gadolinium-chelates, cine CMR at end diastole (c) and end systole (d) in the same imaging plane. A mildly thickened, hypointense appearing pericardium is visible over the right heart (arrows). No enhancement of the thickened pericardium after gadolinium administration (b). The thickened part of the pericardium has a rigid, immobile appearance, while the underlying myocardium exhibits a normal contraction pattern. The dynamic viewing mode allows a better appreciation of the differences in motion between the rigid pericardium and underlying myocardium.
