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.

MaxIP images (a, b) demonstrate an anomalous curvilinear right lower pulmonary vein draining into the inferior vena cava just above the hemi-diaphragm, a classic sign of Scimitar syndrome, in a 10-year-old child. Previous metallic embolisation coils are seen on both images. Scanning parameters: 100 kV, 64 eff mAs, 150 ref mAs, 7.15 CTDIvol, 128 DLP

Fig10: MaxIP images (a, b) demonstrate an anomalous curvilinear right lower pulmonary vein draining into the inferior vena cava just above the hemi-diaphragm, a classic sign of Scimitar syndrome, in a 10-year-old child. Previous metallic embolisation coils are seen on both images. Scanning parameters: 100 kV, 64 eff mAs, 150 ref mAs, 7.15 CTDIvol, 128 DLP

Mentions: Hypogenetic lung syndrome is primarily due to abnormal right lung development that has an anomalous pulmonary venous connection. It is associated with dextrocardia and an anomalous systemic arterial supply to the right lung [27, 31, 32]. Appearances on CT demonstrate a hypoplastic right lung and right pulmonary artery. The ipsilateral anomalous pulmonary vein is curvilinear in shape (like a ‘scimitar’ sword) and drains caudally in increasing diameter towards the inferior vena cava at the level of the right inferior cardiac border (Fig. 10).Fig. 10
