P103 Automated quantitative imaging correlates with lung function and exercise tolerance in patients with idiopathic pulmonary fibrosis.
RATIONALE Automated quantitative imaging may assess disease course and response to therapy in idiopathic pulmonary fibrosis (IPF). However, effort-dependent variability in inspiration impacts measurements. Spirometry-guided high-resolution computed tomography (SG-HRCT) may reduce this variability. Furthermore, it is unknown to what extent quantitative imaging correlates with pulmonary function or exercise tolerance.
