Which of the following positions is required to demonstrate small amounts of air in the peritoneal cavity?Therefore, to demonstrate air or fluid levels, the erect or decubitus position should be used. Small amounts of fluid within the peritoneal or pleural space are best demonstrated in the lateral decubitus position, affected side down.
What procedure is used to demonstrate the pulmonary apices in the AP position?The AP lordotic chest radiograph (or AP axial chest radiograph) demonstrates areas of the lung apices that appear obscured on the PA/AP chest radiographic views.
What position separates the sternum from the vertebral column but places it within the homogeneous heart shadow?a slight oblique (just enough to separate the sternum from superimposition on the vertebrae) is used instead of a direct frontal projection. In the RAO position, the heart superimposes a homogeneous density over the sternum, thereby providing clearer radiographic visualization of its bony structure.
