Moderate pericardial effusion. T1-weighted spin-echo CMR. (a), T2-weighted short-tau inversion-recovery spin-echo CMR (b), and cine CMR (c) in axial image plane. The pericardial effusion (arrowheads), having an inhomogeneous spread, is most pronounced over the right atrium and left ventricle. Systolic collapse of the right atrial wall during systole (arrow)(c). The fluid signal intensity, especially on T2-weighted short-tau inversion-recovery spin-echo CMR, has an inhomogeneous appearance (b). Moderate right-sighted pleural effusion. The collapse of right atrial and right ventricular wall during the cardiac cycle can be well appreciated on cine CMR.
