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.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
Imaging Studies for Cardiovascular System III: X-Ray
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
