T/F: The characteristics used to distinguish between pericardial fat and pericardial effusion are
density of echo
consistent distance between the pericardium and epicardium throughtout the cardiac cycle
distance greater than 2mm between the pericardium and the epicardium
anterior motion of the LV pulmonary wedge pericardium during systole
F,F,F,T
density of echoes is too varied for either pericardial fat or an effusion. Also, the distance is not indicative of either entity. However, with an effusion the pericardium shows a flat pattern and does not remain a constant distance from the epicardium
