Radiation risk to children from computed tomography.
Pediatrics
|September 4, 2007
Summary
Pediatric imaging uses ionizing radiation, including computed tomography (CT) scans. While CT scans carry a small cancer risk, their benefits outweigh risks when medically necessary. Healthcare professionals should minimize radiation exposure and discuss risks with families.
Area of Science:
- Medical Imaging
- Pediatric Radiology
- Radiation Oncology
Background:
- Ionizing radiation is crucial for diagnosing childhood disorders via radiography, fluoroscopy, angiography, and computed tomography (CT).
- Computed tomography (CT) scans are widely used but involve relatively high radiation doses.
- Low-level radiation exposure is associated with a small risk of cancer, necessitating careful consideration in pediatric patients.
Purpose of the Study:
- To review the role of ionizing radiation in pediatric imaging.
- To emphasize the importance of minimizing radiation exposure in children undergoing CT scans.
- To guide healthcare professionals, patients, and families in decision-making regarding CT scans.
Main Methods:
- Review of current literature and consensus statements on radiation risk in pediatric imaging.
- Discussion of the benefits versus risks of indicated CT scans in children.
- Emphasis on the roles of pediatric health care professionals and radiologists in optimizing CT use.
Main Results:
- The benefits of medically indicated CT scans in children generally outweigh the associated risks.
- Minimizing radiation exposure through dose optimization and judicious use is essential.
- Effective communication between healthcare providers, patients, and families regarding risks and benefits is crucial.
Conclusions:
- Pediatric healthcare professionals must judiciously decide when CT scans are necessary.
- Radiologists play a key role in developing optimized pediatric CT protocols.
- Open communication and patient/family engagement are vital for informed decision-making in pediatric imaging.

01:10Computed Tomography
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...

Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and the...
02:59Biological Effects of Radiation
All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they produce ions...

German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with X-rays, and by 1900, X-ray was widely...
