[Imaging of the pleura].

We review the respective informations yielded to the physician bu the different techniques of medical imaging (conventional radiography, ultrasounds, and computed tomography) according to the presentation of pleural diseases. Conventional radiography is always useful for diagnosis. Ultrasound is useful to confirm and localize pleural effusion. Computed tomography contributes to precise the location of pneumothorax and pleural effusion, and the possible underlying pulmonary disorders. Computed tomography also allows to precisely characterize the different types of pleural thickening, including malignant mesothelioma.
