The emergence of multi-detector row CT (MDCT) has established and extended the role of CT especially in paediatric chest imaging. This has altered the way in which data is acquired and is perceived as the 'gold standard' in the detection of certain chest pathologies. The range of available post-processing tools provide alternative ways in which CT images can be manipulated for review and interpretation in order to enhance diagnostic accuracy.
Paediatric imaging technique/protocol together with radiation dose reduction is discussed in detail. The use of different post-processing tools to best demonstrate the wide range of important congenital anomalies and thoracic pathologies is outlined and presented pictorially.
MDCT with its isotropic resolution and fast imaging acquisition times reduces the need for invasive diagnostic investigations. However, users must be vigilant in their imaging techniques to minimise radiation burden, whilst maintaining good image quality. Main Messages • CT examinations should be clinically justified by the referring clinician and radiologist. • MDCT is invaluable for evaluating the central airway, mediastinal structures and lung parenchyma. • MDCT is more sensitive than plain radiographs in detection of structural changes within the lungs.
多排螺旋 CT（MDCT）的出现确立并扩展了 CT 特别是在儿科胸部成像中的作用。这改变了数据采集的方式，被认为是检测某些胸部病变的“金标准”。现有的各种后处理工具提供了替代的方法来操作 CT 图像，以提高诊断准确性。
详细讨论了儿科成像技术/方案以及辐射剂量的降低。概述并以图像形式展示了使用不同的后处理工具来最佳显示广泛的重要先天性异常和胸部病变。
MDCT 具有各向同性分辨率和快速成像采集时间，减少了对有创诊断检查的需求。然而，使用者必须在他们的成像技术中保持警惕，以尽量减少辐射负担，同时保持良好的图像质量。
主要信息
CT 检查应由主治临床医生和放射科医生进行临床评估。
MDCT 对评估中央气道、纵隔结构和肺实质非常有价值。
MDCT 在检测肺部结构变化方面比普通 X 线片更敏感。
