Figure 1. Lung fibrosis, CT scan. This is the bottom of the lung with the aortic branches (purple), nonlung tissue (blue), lung tissue (yellow/blue) and air-filled bullae (orange). 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.
