Insights
Brain computed tomography (CT) is effective for detecting pediatric facial fractures, performing comparably to 3D CT but with a lower radiation dose. This makes brain CT a suitable initial imaging choice for trauma patients.
Area of Science:
- Radiology
- Pediatric Imaging
- Trauma Imaging
Background:
- Facial fractures are common in pediatric trauma.
- Accurate and efficient imaging is crucial for diagnosis and treatment planning.
Purpose of the Study:
- To compare the diagnostic performance of brain computed tomography (CT) versus facial 3-dimensional (3D) CT.
- To evaluate radiation dose differences between the two CT modalities.
- To assess their utility in pediatric trauma patients with suspected facial fractures.
Main Methods:
- Retrospective analysis of 400 pediatric trauma patients.
- Independent review of brain CT and facial 3D CT for facial fractures in 8 anatomic regions.
- Evaluation of treatment decisions and interobserver agreement.
- Comparison of diagnostic accuracy and radiation effective dose.
Main Results:
- Brain CT demonstrated high sensitivity (94.1%-96.5%) and specificity (99.7%-100%), performing comparably to facial 3D CT.
- No significant difference in suggested treatment decisions between the two modalities.
- Mean effective radiation dose was significantly lower for brain CT (3.6 mSv) compared to facial 3D CT (5.5 mSv).
Conclusions:
- Brain CT offers acceptable diagnostic performance for pediatric facial fractures.
- Brain CT can serve as a primary imaging tool in the initial evaluation of pediatric trauma patients with suspected facial fractures.
- Utilizing brain CT reduces radiation exposure compared to dedicated facial 3D CT.
Objectives:
To compare the detection of facial fractures and radiation dose between brain computed tomography (CT) and facial 3-dimensional (3D) CT in pediatric patients who have experienced a trauma.
Study Design:
Four hundred pediatric patients who experienced a trauma and underwent immediate brain CT and facial 3D CT between January 2016 and June 2016 were included in this retrospective study. Two reviewers independently analyzed and determined the presence of the facial fractures of 8 anatomic regions based on brain CT and facial 3D CT over a 1-week interval. Suggested treatment decisions for facial fractures seen on brain CT and facial 3D CT were evaluated by one physician. The facial 3D CT scans, interpreted by a senior radiologist, were considered as the reference standard. Diagnostic performance, radiation dose, and interobserver agreement of the CT scans were evaluated.
Results:
Brain CT showed a high sensitivity (94.1%-96.5%), high specificity (99.7%-100%), and high accuracy (98.8%-99.0%) in both reviewers, and performed as well as did facial 3D CT (P ≥ .25). The suggested treatment decision was not different between the brain CT and facial 3D CT findings. The agreements between the reference standard and the reviewers, and between reviewers 1 and 2 were excellent (k = 0.946-0.993). The mean effective radiation doses used in brain CT (3.6 mSv) were significantly lower than those in brain CT with facial 3D CT (5.5 mSv) (P < .001).
Conclusions:
Brain CT showed acceptable diagnostic performance and can be used as the first-line imaging tool in the workup of pediatric patients with suspected facial fractures.

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...
