Synopsis

Keywords: Lung, Lung

This preliminary study investigates the utility of high-resolution 3D-UTE to assess patients with CTD-ILD and their pulmonary function, including both pulmonary parenchyma and lesions, using OE-UTE-MRI. Our results suggest that high-resolution 3D UTE and OE-UTE MRI could potentially be as useful as thin-section CT for lesion detection of CTD patients with ILD and provide additional pulmonary functional loss assessment.
