Paediatric multi-detector row chest CT: what you really need to know.

Young C, Xie C, Owens CM - Insights Imaging (2012)

Bottom Line: Paediatric imaging technique/protocol together with radiation dose reduction is discussed in detail.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.

ABSTRACT

Background: 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.

Methodology: 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.

Conclusion: 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.

a, b Different rendering software highlights different anatomical structures, as illustrated in these images of a 2-month-old child with congenital emphysema. a Using the MaxIP application, the parenchymal vasculature is clearly seen in the coronal and axial images (i and ii), even within the affected lobes. b Coronal (iii) and axial (iv) MinIP reformatted images show the central airway together with segmental air trapping, easily visualised within both lower lobes.

Mentions: Maximum intensity projection (MaxIP) is a rendering tool that extracts a volume of a contrast-enhanced anatomical structure that is then displayed as an angiography study. It is particularly useful in highlighting peripheral vessels and in visualising nodules and vessels and also in distinguishing discrete parenchymal nodules from branching vascular structures [4] (Fig. 3a).Fig. 3
