Insights
Whole-body MRI (WBMR) offers a radiation-free diagnostic imaging alternative for severely injured children, though it may require longer scan times and sedation. Whole-body CT (WBCT) is faster but involves radiation exposure.
Area of Science:
- Pediatric Traumatology
- Diagnostic Imaging
- Radiology
Background:
- Serious accidents are a leading cause of pediatric mortality, necessitating efficient diagnostic protocols.
- Whole-body imaging, including magnetic resonance imaging (WBMR) and computed tomography (WBCT), is utilized for diagnosing severely injured children.
Purpose of the Study:
- To compare the effectiveness and outcomes of WBMR versus WBCT in pediatric trauma patients.
- To evaluate differences in patient demographics, injury severity, diagnostic time, and need for sedation between WBMR and WBCT.
Main Methods:
- Retrospective review of 134 WBMR and 158 WBCT examinations in patients under 16 years old.
- Data collected from two trauma centers between 2007 and 2018.
- Analysis of Injury Severity Score (ISS), age, diagnostic time, mortality, and sedation requirements.
Main Results:
- WBCT showed a higher ISS (10.6 vs. 5.8) but no significant difference in mortality compared to WBMR.
- WBMR was preferred for younger children (9.6 vs. 12.8 years).
- WBCT diagnostic time was significantly longer (92.1 vs. 37.1 min), with more patients requiring analgesic sedation and/or intubation (37.3% vs. 21.6%).
Conclusions:
- Whole-body MRI is a viable, radiation-free imaging option for high-energy pediatric trauma.
- While effective, WBMR may involve longer diagnostic durations and increased need for sedation compared to WBCT.
- Further research is warranted to optimize imaging protocols and address limitations in pediatric trauma diagnosis.
Abstract:
Although serious accidents remain the leading cause of pediatric mortality, protocols to orient diagnostic procedures towards a certain type of initial imaging are widely needed. Since 2007, we have performed whole-body magnetic resonance imaging (WBMR) and whole-body computed tomography (WBCT) for diagnoses of severely injured children. We retrospectively reviewed 134 WBMR and 158 WBCT in patients younger than 16 years that were performed at two trauma centers between 2007 and 2018. A higher Injury Severity Score (ISS) was found in WBCT vs. WBMR (10.6 vs. 5.8; p = 0.001), but without any significant difference in mortality. The WBMR was significantly preferred at younger ages (9.6 vs. 12.8 years; p < 0.001). The time between patient's arrival until diagnosis was 2.5 times longer for WBCT (92.1 vs. 37.1 min; p < 0.001). More patients in the CT group received analgesic sedation and/or intubation at 37.3% vs. 21.6% in the MRI group. Of these patients, 86.4% (CT) and 27.6% (MRI) were already preclinically sedated (p < 0.001). Correspondingly, 72.4% of the patients were first sedated in-hospital for MRIs. In conclusion, WBMR is an alternative and radiation-free imaging method for high-energy-traumatized children. Although the selected diagnostics seemed appropriate, limitations regarding longer duration or additional analgesic sedation are present, and further studies are needed.
