Insights
Microsievert wide-volume computed tomography (μSv-WV-CT) offers similar diagnostic performance for foreign body aspiration in children as multidetector computed tomography with automatic exposure control (MDCT-AEC), but with significantly lower radiation doses.
Area of Science:
- Pediatric Radiology
- Diagnostic Imaging
- Radiation Safety
Background:
- Foreign body aspiration (FBA) in children is a critical condition requiring immediate diagnosis and management.
- Various imaging techniques are employed for FBA diagnosis, each with implications for radiation exposure.
Purpose of the Study:
- To compare the diagnostic efficacy and radiation dose of microsievert wide-volume computed tomography (μSv-WV-CT) versus multidetector computed tomography with automatic exposure control (MDCT-AEC) in pediatric FBA cases.
Main Methods:
- A retrospective analysis of 102 pediatric FBA cases diagnosed between 2013 and 2021.
- Patients were stratified into two groups based on imaging modality: μSv-WV-CT (2016-2021) and MDCT-AEC (2013-2021).
- Statistical comparison of diagnostic performance metrics and radiation doses between the two groups.
Main Results:
- Both μSv-WV-CT and MDCT-AEC demonstrated comparable diagnostic performance, including sensitivity, specificity, and accuracy.
- The mean effective radiation dose for μSv-WV-CT was significantly lower (34.89 ± 0.01 μSv) compared to MDCT-AEC (179.75 ± 114.88 μSv) (P < 0.001).
Conclusions:
- μSv-WV-CT provides a diagnostic performance equivalent to MDCT-AEC for evaluating suspected FBA in children.
- μSv-WV-CT represents a safer imaging option due to its substantially reduced radiation dose.
Background:
Foreign body aspiration (FBA) in childhood is a life-threatening condition that necessitates prompt management to prevent devastating complications. Different imaging methods are used in the diagnosis of FBA.
Objective:
The aim of this study was to compare the diagnostic value and dose of microsievert wide-volume computed tomography (μSv-WV-CT) with multidetector computed tomography using an automatic exposure control system (MDCT-AEC) in children with FBA.
Material And Methods:
In this single-center cross-sectional study, 102 cases diagnosed with FBA between September 2013 and September 2021 were retrospectively evaluated. The patients were divided into 2 groups according to the diagnostic modality used: group A, μSv-WV-CT (2016-2021) and group B, MDCT-AEC (2013-2021). The diagnostic performance and radiation dose of the 2 groups were statistically compared.
Results:
The diagnostic performance (sensitivity, specificity, positive predictive value, negative predictive value, and accuracy) of the 2 groups was similar. The mean effective radiation dose of group A was 34.89 ± 0.01 μSv, which was significantly lower than that of group B (179.75 ± 114.88 μSv) ( P < 0.001).
Conclusion:
In children with suspected FBA, μSv-WV-CT at a lower radiation dose had similar diagnostic performance to MDCT-AEC.

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...
