title: Magnetic resonance imaging and high-resolution computed tomography in tumors of the lung and the mediastinum.
abstract: Magnetic resonance (MR) imaging and high resolution computed tomography (CT) have been compared in 37 patients who had expansive processes of the lung and the mediastinum. MR imaging and CT scanning gave identical results in 32 patients; in 5 patients, CT scanning has proved more useful in evaluating the stag e of primary lung tumors. MR imaging often gives more information about the actual size of the tumor, and the involvement of close structures, although it does not modify staging of the tumor. MR imaging has the advantage to differentiate hilar adenopathy from blood vessel structures. Evaluation of T2 relaxing time (that we have performed in the same location of thin-needle biopsy aspiration), however, did not prove to be of diagnostic significance; this indicates that MR imaging at the moment is not suitable for tissue typification.
