The lateral decubitus position is a fundamental patient orientation employed in medical imaging. The patient lies on their side, either left or right, with the body's longitudinal axis perpendicular to the imaging table.
Terminology
By convention the side that is down in contact with the table names the position; left lateral decubitus is left side down, right lateral decubitus is right side down.
Usage
The lateral decubitus position is used in a variety of settings when gravity is important in the movement of gas or contrast, or for the purposes of patient positioning for procedures.
