Summary
Pediatric upper extremity X-rays show a wide range of radiation doses, varying by exam type and age. New computational models provide better estimates for effective and organ doses in these crucial imaging procedures.
Area of Science:
- Medical Imaging
- Radiological Physics
- Pediatric Radiology
Background:
- Upper extremity radiographic exams are often treated as a single category with simplified dose estimates.
- Limited tools exist for simulating or calculating radiation dose from these varied exams.
Purpose of the Study:
- To evaluate effective and organ doses from pediatric upper extremity radiographic exams.
- To utilize novel hybrid computational phantoms for accurate dose assessment across different ages and sexes.
Main Methods:
- Collected technical parameters for pediatric upper extremity exams based on age categories.
- Established relationships between acquisition parameters and dose-area product.
- Employed Monte Carlo simulations with new computational phantoms for dose calculations.
Main Results:
- Effective dose ranged from 0.01 µSv (hand/finger, 3-6 yrs) to 1.13 µSv (humerus, 1-3 yrs).
- Skin, muscle, endosteum, and red marrow received the highest organ doses.
- Conversion coefficients for estimating effective and organ doses from dose-area product were calculated.
Conclusions:
- Newly developed computational phantoms reveal significant variability in effective and organ doses for pediatric upper extremity radiographs.
- Reported doses can aid in site-specific estimations for radiation protection.

16.1K
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...

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...

301
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...
