[Computed tomography of the chest in children : Indications, technical optimization, and future perspectives].

BACKGROUND

Computed tomography (CT) of the chest is an indispensable tool in pediatric radiology, but it imposes particular challenges.

OBJECTIVE

This review article presents a practice-oriented approach to optimizing thoracic CT in children, from clinical indications to technical execution and new technologies.

MATERIALS AND

METHODS

A critical review of relevant scientific publications and guidelines was performed.

RESULTS

Optimizing pediatric chest CT requires strict indications, adaptation of scan parameters (especially tube voltage) to pediatric physiology, and the use of specific protocols (e.g., high resolution CT [HRCT], low-dose CT). Image reconstruction and postprocessing (maximum intensity projection [MIP], minimum intensity projection [MinIP], volume rendering technique [VRT]) are crucial for diagnosis. Dose monitoring using diagnostic reference levels (DRLs) and ADs is essential.w

CONCLUSION

Recent developments, particularly photon-counting CT, are discussed regarding their potential to improve image quality and reduce radiation exposure in the context of thoracic imaging.
