title: MRI of tracheobronchomegaly.
abstract: Tracheobronchomegaly, a disorder of uncertain etiology, is manifested by the enlargement of the trachea and mainstem bronchi. While the diagnosis may be suggested on chest radiographs, bronchography in the past has been the definitive diagnostic modality. Recently, however, computed tomography has been used to confirm the diagnosis of TBM. We have now demonstrated TBM using MRI, and, in this patient, have shown it to be as good as CT.
