ABSTRACT
The pericardium is visible in each of the standard imaging planes of the heart and should therefore be examined in each view. As the normal pericardium is thin (1–2 mm) it is not prominent on echo, but may appear as a thin bright line around the heart. The trace of pericardial fluid that is normally present may be visible as a thin black line separating the two layers of the serous pericardium (Fig. 25.1).
