Evaluation of the Pericardium with CT and MR.

Czum JM, Silas AM, Althoen MC - ISRN Cardiol (2014)

Bottom Line: The pericardium plays an important role in optimizing cardiac motion and chamber pressures and serves as a barrier to pathology.In addition to pericardial anatomy and function, this review article covers a variety of pericardial conditions, with mention of potential pitfalls encountered during interpretation of diagnostic imaging.Normal and abnormal appearance of pericardium on CT and MR imaging is emphasized, including dynamic imaging correlates of pericardial pathophysiology.

ABSTRACT
The pericardium plays an important role in optimizing cardiac motion and chamber pressures and serves as a barrier to pathology. In addition to pericardial anatomy and function, this review article covers a variety of pericardial conditions, with mention of potential pitfalls encountered during interpretation of diagnostic imaging. Normal and abnormal appearance of pericardium on CT and MR imaging is emphasized, including dynamic imaging correlates of pericardial pathophysiology.

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.

(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.

Mentions: As with the other serosal surfaces of the body, the pericardium has parietal and visceral layers. The parietal layer of pericardium is several times thicker than the visceral pericardium [4]. The normal combined pericardial thickness is 2 mm or less (Figures 1(a) and 1(b)). 2-3 mm is considered equivocal, whereas 4 mm thickness at any point is abnormal [9, 10]. The normal pericardial stabilizers include the great vessel reflections and several ligaments (pericardial-sternal, pericardial-vertebral, and pericardial-diaphragmatic) (Figure 1(c)) [4].
