High-resolution CT (HRCT) is the radiological imaging technique that most closely reflects changes in lung structure. It represents the radiological method of choice for the diagnostic work-up of patients with known or suspected diffuse interstitial lung disease. A single HRCT finding is frequently nonspecific, but the combination of the various HRCT findings together with their anatomic distribution can suggest the most probable diagnosis. The purpose of this article is to summarize the classic HRCT features of the most common diffuse interstitial lung diseases. Lists of differential diagnoses and distinguishing key features are provided to improve diagnostic confidence. The presence of classic HRCT features often obviates the need for biopsy. In patients with atypical findings, HRCT can be used to determine the most appropriate biopsy site.
高分辨率计算机断层扫描（HRCT）是最能紧密反映肺部结构变化的放射成像技术。它是已知或疑似弥漫性间质性肺疾病患者诊断检查的首选放射学方法。单一的HRCT表现往往是非特异性的，但各种HRCT表现及其解剖分布的组合可提示最可能的诊断。本文的目的是总结最常见的弥漫性间质性肺疾病的典型HRCT特征。提供鉴别诊断列表和鉴别关键特征以提高诊断信心。经典HRCT特征的存在常常使活检不再必要。对于有非典型表现的患者，HRCT可用于确定最合适的活检部位。
