Estimation of Lung Volume Superimposed on the Mediastinum and Diaphragm on Chest Radiographs Using Upright Multidetector Row CT

Key Points

• The research aims to compare lung volume superimposed on the mediastinum and diaphragm between upright and supine chest radiographs.
• Analyzed lung volumes using multidetector row CT
• Compared upright and supine chest radiographs
• Lung volume superimposed on the mediastinum and diaphragm was lower on upright radiographs compared to supine
• Upright positioning yielded greater overall lung volume
