Summary
Establishing Diagnostic Reference Levels (DRLs) for pediatric computed tomography (CT) is crucial. This review highlights global variations in DRLs and calls for standardized protocols to optimize radiation doses for children.
Area of Science:
- Radiology
- Medical Physics
- Pediatric Imaging
Background:
- Computed tomography (CT) is essential for diagnosing pediatric pathologies.
- Children are more susceptible to radiation adverse effects than adults.
- Diagnostic Reference Levels (DRLs) help optimize radiation doses in CT examinations.
Purpose of the Study:
- To review existing literature on DRLs in pediatric CT examinations.
- To identify techniques used for establishing pediatric CT DRLs.
- To assess global trends and variations in pediatric CT DRLs.
Main Methods:
- Systematic literature search across major databases (PubMed-Medline, Scopus, CINAHL, Web of Science, Cochrane Library).
- Application of Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) methodology.
- Inclusion of 21 relevant articles out of 501 identified studies.
Main Results:
- Increased global pediatric patient dose surveys and DRLs awareness.
- Significant variations observed in established DRLs worldwide.
- Discrepancies noted in scanning techniques, protocols, and categorization methods for DRL establishment.
Conclusions:
- There is a growing need for optimizing pediatric CT protocols.
- International standardization of DRLs is essential for global dose comparison.
- Standardization will facilitate feasible comparison of radiation doses across different CT sites.

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
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...

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
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...

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...
