title: Comparison of the liver's respiratory motion in the supine and upright positions: concise communication.
abstract: The effect of the upright position, compared with the supine position, in reducing respiratory motion during liver scintigraphy has been measured in a group of 51 randomly selected patients. Little improvement in spatial resolution can be expected from simply standing the patient upright, and analog motion correction is recommended as much more effective in minimizing respiratory motion artifacts in liver scintigraphy.
