COMPUTED-TOMOGRAPHY (CT) AND MAGNETIC-RESONANCE-IMAGING (MRI) OF PLEURAL MASSES

Depending on the location, size, and underlying histologic features, pleural masses may produce a large spectrum of findings. While a number of imaging modalities may be used, plain chest radiographs remain the most common examination in the initial assessment of these patients. In this article, we review the use of two noninvasive techniques: computed tomography and magnetic resonance imaging. For die purpose of this review, localized pleural masses and diffuse pleural masses are discussed separately. Among die various pleural masses, metastatic disease represents the most frequent neoplasm.
