Abstract

The Fleischner Society white paper and the American Thoracic Society (ATS)/European Respiratory Society (ERS)/Japanese Respiratory Society (JRS)/Latin American Thoracic Association (ALAT) guidelines recently redefined the computed tomography (CT) scanning patterns of usual interstitial pneumonia (UIP) [1, 2]. Both publications confirmed honeycombing as the cornerstone of UIP pattern diagnosis, and introduced peripheral traction bronchiolectasis (PTB) as a key feature of the new "probable UIP" category. Therefore, improving the distinction between these two features may be critical, especially when the clinical likelihood of idiopathic pulmonary fibrosis (IPF) is uncertain; a lung biopsy should be discussed for patients with PTB without honeycombing, but is not recommended for patients presenting with clear honeycombing and typical UIP pattern [2]. On chest CT, post-processing with minimal intensity projection does not improve inter-reader agreement for the identification of peripheral traction bronchiolectasis and honeycombing in patients with suspected idiopathic interstitial pneumonia. http://bit.ly/35p8NlQ
