Overview

An x-ray is helpful in the diagnosis of diaphragmatic paralysis. Findings on an x-ray suggestive of unilateral diaphragmatic paralysis include elevated hemidiaphragm in the paralysed side, small lung volumes. Findings on an x-ray suggestive of bilateral diaphragmatic paralysis include smooth elevation of the hemidiaphragms and atelectasis at the lung base
