The usual interstitial pneumonia (UIP) pattern on high-resolution CT (HRCT) is the hallmark pattern for IPF. On imaging UIP pattern usually presents with lung volume loss, reticular opacities, traction bronchiolectasis, and honeycombing with peripheral distribution and basal predominance. Pulmonary hypertension may be seen in the advanced stages of IPF. In some patients, to detect early or mild IPF, prone imaging may be necessary.

Imaging of patients with fibrotic hypersensitivity pneumonitis typically demonstrate predominant patchy ground-glass or nodular opacities in a bronchovascular distribution and evidence of air trapping.
