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.

MDCT images of a child with a single pulmonary vein with severe narrowing at the junction where it enters the posterior aspect of the left atrium. This can be seen clearly on both the axial MaxIP image (a) and on the VRT image (b). MDCT is the investigation of choice in patients with venous stenosis due to the superior spatial resolution of CT over MRI. Scanning parameters: 80 kV, 38 eff mAs, 130 ref mAs, 0.66 CTDIvol, 8 DLP

Fig21: MDCT images of a child with a single pulmonary vein with severe narrowing at the junction where it enters the posterior aspect of the left atrium. This can be seen clearly on both the axial MaxIP image (a) and on the VRT image (b). MDCT is the investigation of choice in patients with venous stenosis due to the superior spatial resolution of CT over MRI. Scanning parameters: 80 kV, 38 eff mAs, 130 ref mAs, 0.66 CTDIvol, 8 DLP

Mentions: Pulmonary vein stenosis is due to uncontrolled proliferation of myofibroblast-like connective tissue cells resulting in thickening and narrowing of the pulmonary vein(s) at the junction with the left atrium [32, 36, 37] (Fig. 21). This anomaly commonly occurs with others (congenital heart disease and total anomalous pulmonary venous return).Fig. 21
