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.

Coronal and axial images show a well-defined water density lesion lying within the mediastinum. There is no systemic arterial supply to the lesion, and it is not connected to the tracheobronchial tree. Appearances are compatible with a mediastinal bronchogenic cyst. Scanning parameters: 80 kV, 57 eff mAs, 60 ref mAs, 0.85 CTDIvol, 13 DLP

Fig14: Coronal and axial images show a well-defined water density lesion lying within the mediastinum. There is no systemic arterial supply to the lesion, and it is not connected to the tracheobronchial tree. Appearances are compatible with a mediastinal bronchogenic cyst. Scanning parameters: 80 kV, 57 eff mAs, 60 ref mAs, 0.85 CTDIvol, 13 DLP

Mentions: Bronchogenic cysts are thin-walled mucoid or serous cysts caused by anomalies in lung development due to abnormal budding of the ventral embryonic foregut. The cysts are most commonly located in the mediastinum (mediastinal bronchogenic cysts) adjacent to the tracheobronchial tree but do not communicate with it and may cause extrinsic compression (Fig. 14). Peripheral (pulmonary) bronchogenic cysts are usually solitary and commonly seen in the lower lobes.Fig. 14
