Why the study?
Does ultrasound reliably determine the presence of a pericardial effusion?
Does ultrasound reliably determine the presence of a pericardial effusion?
Ultrasound provides a reliable method for detecting pericardial effusion by identifying a bare area between echoes from the chest wall and myocardium.
Ultrasound may enable noninvasive pericardial effusion detection; leaves open diagnostic accuracy and clinical adoption pending validation.
A reliable method of determining the presence of a pericardial effusion has been evolved. Ultrasonic waves reflected from the posterior part of the anterior chest wall and from the anterior surface of the anterior myocardium and pericardium produce echoes separated from each other by a bare area. This bare area varies in width and the variation has the same periodicity as the cardiac cycle.
