    Abstract:
    Nineteen patients with potentially operable bronchial carcinoma were included in a prospective study to assess the staging capabilities of plain and contrast-enhanced magnetic resonance imaging (MRI) in comparison with computed tomography (CT) and to compare the results to post-operative histopathological staging (HS). The evaluation focused on the following T-staging criteria: (i) direct invasion of the pleura; (ii) neoplastic invasion of the mediastinum; (iii) differentiation of the primary tumour from alterations of the surrounding lung parenchyma such as inflammation or atelectasis; and (iv) intrathoracic lymph node involvement by tumour. MRI and CT produced similar results for pleural invasion (sensitivity of 0.4 and 0.75 respectively and a specificity of 0.86 and 0.93 respectively). Mediastinal invasion was overdiagnosed in four patients (no false negatives), whereas CT had only one false positive result (two false negatives). Our results showed CT to be superior to MRI for the preoperative evaluation of patients suffering from bronchogenic carcinoma.
