The supine anteroposterior chest view is the alternative to the PA view[1] and the AP erect[2] view[3] when the patient is generally too unwell to tolerate standing, leaving the bed, or sitting 1. The supine view is of lesser quality than both the AP erect and the PA view for many reasons, yet sometimes it is the only imaging available to the patient.

The supine view examines the lungs[4], bony thoracic cavity mediastinum[5] and great vessels[6]. This particular chest radiograph is often used to aid diagnosis of acute trauma abnormalities, or chronic conditions in intensive care units and wards.

It is important to note that the supine projection will produce a magnified mediastinal shadow due to the increased distance of the heart from the image receptor and beam divergence (see figure 1 AP supine and figure 2 PA projection of the same patient).
