Imagerie des troubles de ventilation

Abstract

Atelectasis is one of the most commonly encountered abnormalities in chest radiology. The presence of such abnormality must be considered on the basis of a standard face chest X-ray, eventually helped by a lateral view. These disorders of ventilation may be related to a decrease (atelectasis or collapse) or an increase (air trapping) of the lung volume. In this article, following a brief review of the different radiological techniques and radio anatomy of lung segmentation, we describe the pathophysiology, mechanisms and radiological signs of ventilation disorders. We underline the essential role of CT scanning and the recently highlighted potentialities of multiplan reconstruction.
