CLINICAL/METHODICAL ISSUE: For optimal visualization of the lung parenchyma a dedicated computed tomography (CT) examination protocol has to be selected.
STANDARD RADIOLOGICAL METHODS
High resolution CT (HRCT) is the best technique for non-invasive evaluation of the lung parenchyma.
ACHIEVEMENTS
Given the possibility to examine the complete lungs within one breath hold, assessment of disease severity and distribution is easily possible. Various parameters have to be considered to generate optimal image quality and best possible clinical results.
PRACTICAL RECOMMENDATIONS
This review article discusses the various image acquisition parameters for HRCT as well as the issue of dose reduction.
临床/方法学问题：为了实现肺实质的最佳可视化，必须选择专门的计算机断层扫描（CT）检查方案。
标准放射学方法
高分辨率CT（HRCT）是对肺实质进行无创评估的最佳技术。
成果
鉴于能够在一次屏气内检查整个肺部，很容易对疾病的严重程度和分布进行评估。为了生成最佳图像质量和尽可能好的临床结果，必须考虑各种参数。
实用建议
这篇综述文章讨论了HRCT的各种图像采集参数以及剂量降低问题。
