Normal pericardium. (a) Gated contrast-enhanced axial CT and (b) axial double inversion recovery MR images from the same patient show the normal thickness pericardium (parietal and visceral layers indistinguishable) sandwiched between epicardial and pericardial fat layers. (c) A sagittal postcontrast gradient MR image demonstrates both pericardial-diaphragmatic (black arrow) and pericardial-sternal (white arrow) ligaments.
