hemithorax การใช้

• An air rim of 2 cm means that the pneumothorax occupies about 50 % of the hemithorax.
• LD is roughly defined as a locoregional tumor burden confined to one hemithorax that can be encompassed within a single, tolerable radiation field, and without detectable distant metastases beyond the chest or supraclavicular lymph nodes.
• Blunting of the lateral costophrenic angle usually requires about 175 mL but may take as much as 500 mL . Larger pleural effusions opacify portions of the hemithorax and may cause mediastinal shift; effusions > 4 L may cause complete opacification of the hemithorax and mediastinal shift to the contralateral side.
