Radiologic imaging in myasthenia gravis is used for the evaluation of pathologic changes of the thymus gland. Computed tomography can demonstrate tumors of the anterior mediastinum in nearly 90% and is therefore superior to conventional radiography. Because of the variety of size and shape of the normal thymus gland, differentiation between normal thymus, follicular hyperplasia and thymoma is rarely possible especially in younger patients. In elderly patients with myasthenia gravis and involution of the thymus gland tumors of the thymus are reliably detected by computed tomography, whereas the ability of computed tomography to predict the histological diagnosis is poor even with intravenous administration of contrast media.
重症肌无力的放射影像学检查用于评估胸腺的病理变化。计算机断层扫描可显示近90%的前纵隔肿瘤，因此优于传统放射摄影。由于正常胸腺的大小和形状各异，尤其是在年轻患者中，很难区分正常胸腺、滤泡增生和胸腺瘤。在患有重症肌无力且胸腺萎缩的老年患者中，计算机断层扫描可可靠地检测到胸腺肿瘤，而即使静脉注射造影剂，计算机断层扫描预测组织学诊断的能力也很差。
