Mass lesions in the chest can usually be best evaluated by conventional means, primarily plain chest film examination. Fluoroscopy is often useful, especially to differentiate normal thymus from abnormal anterior mediastinal masses and to evaluate possible vascular masses. It makes sense to do a barium swallow for most middle mediastinal masses before resorting to the more expensive CT or MRI. In addition to the added expense, the marked increase in radiation dose should also be considered when CT is contemplated.
胸部的占位性病变通常可以通过传统方法进行最佳评估，主要是胸部X线平片检查。荧光透视检查通常很有用，特别是用于区分正常胸腺与异常前纵隔肿块以及评估可能的血管性肿块。对于大多数中纵隔肿块，在采用更昂贵的CT或MRI之前，先进行吞钡检查是合理的。除了费用增加外，考虑进行CT检查时还应考虑辐射剂量的显著增加。
