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

外周牵引性细支气管扩张的 CT 评估：最小强度投影的影响

Fleischner 学会白皮书和美国胸科学会 (ATS)/欧洲呼吸学会 (ERS)/日本呼吸学会 (JRS)/拉丁美洲胸科学会 (ALAT) 指南最近重新定义了常见间质性肺炎的计算机断层扫描 (CT) 扫描模式(UIP) [1, 2]。两份出版物都确认蜂窝状是 UIP 模式诊断的基石，并介绍了外周牵引性细支气管扩张 (PTB) 作为新的“可能的 UIP”类别的关键特征。因此，改善这两种特征之间的区别可能至关重要，尤其是当特发性肺纤维化 (IPF) 的临床可能性不确定时；对于没有蜂窝状结构的 PTB 患者，应讨论肺活检，但不建议对具有清晰蜂窝状结构和典型 UIP 模式的患者进行肺活检 [2]。在胸部 CT 上，使用最小强度投影进行后处理并不能提高阅读者间识别疑似特发性间质性肺炎患者外周牵引性细支气管扩张和蜂窝状的一致性。http://bit.ly/35p8NlQ
