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.

Surface shaded display of the intra-luminal surface of the trachea (a–b) seen superiorly towards the carina. The images show marked AP compression of the trachea. Axial image (c) confirms the tracheal compression between the innominate artery anteriorly and a dilated oesophagus posteriorly. Scanning parameters: 80 kV, 35 eff mAs, 150 ref mAs, 0.58 CTDIvol, 9 DLP

Mentions: Virtual bronchoscopy (VB) is a surface-shaded display (SSD) that produces an image that mimics a bronchoscopic view of the intraluminal surface of the tracheobronchial tree. The operator can visualise and traverse the length of the trachea and bronchus in ‘real-time’ and ‘cross’ obstructions that an endoscope cannot traverse. It is useful in cases where conventional bronchoscopy is contra-indicated or in tracheal stenosis that cannot be otherwise evaluated in three-dimensions [7] (Fig. 5).
