Computed tomography (CT) scanning and magnetic resonance imaging (MRI) of the chest are each highly accurate in detecting thymomas. Every patient with myasthenia gravis should be screened for these neoplasms. Chest radiography is relatively insensitive in screening for thymomas, as it does not detect them in up to 30% of cases.
