Inter- and Intra-examiner Reliability of Quantitative Assessment of Respiratory Muscle Cross-Sectional Areas on Preoperative Chest CT Images: A Pilot Study

This study confirmed excellent intra- and inter-rater reliability for measuring respiratory muscle CSAs using CT images in patients with preoperative lung cancer in the pectoral and intercostal muscles. This suggests that CT assessment of respiratory muscle volume may be widely used as a clinically useful indicator. Further standardization and simplification of this method will allow its use in broader clinical settings.
