[Magnetic resonance imaging of pulmonary coin lesion and bronchopulmonary cancer].

Magnetic resonance imagery (MRI) is less sensitive than computed tomography (CT) for the detection of pulmonary masses and cannot detect calcifications within such masses. MRI performed during the work-up for bronchial cancers has often been compared with CT scans: neither T nor N can be evaluated with more precision. Nevertheless, there are certain specific indications such as the exploration of proximal tumours with suspected extension into the mediastinum including cardiac and vascular invasion, tumours of the aorto-pulmonary window, the Pancoast-tobias syndromes, and tumours situated near the thoracic wall or the spine.
