Lung fibrosis is a condition whereby a lung infection causes inflammation of the tissue around the alveoli (air sacs), producing scar tissue.
Chest radiographs are often the first indicator of an ILD; however, they can appear normal in patients with ILD, according to Walsh and colleagues. The diagnostic accuracy of chest radiographs in suspected ILD is ∼80%.
High-resolution computed tomography (HRCT) is a more sensitive modality for the recognition of ILD than chest radiography or conventional chest CT. According to the 2018 American Thoracic Society/European Respiratory Society clinical practice guidelines for the diagnosis of IPF, HRCT plays a crucial role in the diagnosis of ILD.
