Quizplus · Accepted Answer

Air-fluid levels, indicative of free air or fluid in a body cavity such as the abdomen or pleural space, are best demonstrated in positions that allow the air or fluid to settle and create a visible interface on imaging. These positions include upright and lateral decubitus. The lateral position can also demonstrate air-fluid levels but is not as commonly used for this specific purpose as the upright and lateral decubitus positions.
