CT Densitometry as a Predictor of Pulmonary Function in Lung Cancer Patients

摘要

Purpose:Preoperative pulmonary assessment is undertaken in patients with resectable lung cancer to identifythose at increased risk of perioperative complications. Guidelines from the American College of Chest Physicians indicatethat if the FEV1 and DLCO are ≥60% of predicted, patients are suitable for resection without further evaluation.The aim of our study is to determine if quantitative measures of lung volume and density obtained from pre-operative CTscans correlate with pulmonary function tests. This may allow us to predict pulmonary function in patients with lungcancer and identify patients who would tolerate surgical resection.
