Insights
Magnetic resonance imaging (MRI) is more sensitive than computed tomography (CT) for detecting brain injuries in children with severe head trauma. MRI is recommended, especially when CT scans are normal but deficits persist.
Area of Science:
- Pediatric neurology
- Neuroradiology
- Traumatic brain injury research
Background:
- Severe head injuries in children can lead to long-term neurological deficits.
- Initial assessment often relies on cranial computed tomography (CT).
- The sensitivity of CT in detecting subtle or non-hemorrhagic lesions may be limited.
Purpose of the Study:
- To correlate initial cranial CT findings with long-term follow-up MRI in pediatric severe head injury.
- To evaluate the frequency and location of lesions identified exclusively by MRI.
Main Methods:
- A prospective study followed 70 children with severe head injury and initial pathological CT scans.
- Long-term follow-up was conducted using MRI, with a mean follow-up time of 3 years.
Main Results:
- 71% of children showed pathological findings on follow-up MRI.
- MRI revealed parenchymal lesions in 43% of children with subdural bleeding and in all children with epidural bleeding.
- 44% of children had parenchymal lesions on MRI that were not initially or retrospectively detectable on CT.
- 16 corpus callosum lesions were identified solely by MRI.
Conclusions:
- MRI demonstrates higher sensitivity than CT for non-hemorrhagic parenchymal lesions and diffuse axonal injury in children.
- MRI is recommended for children with severe head injury, particularly those with normal CT scans but persistent post-traumatic neurological deficits.
Purpose:
A prospective study was initiated for the correlation of the findings in the initial cranial CT with the long-term follow-up MRI in children with severe head injury. Another aim was the evaluation of frequency and location of lesions, found only in MRI.
Methods:
70 children with severe head injury and initially performed pathological CCT were followed up (mean time 3 years) by MRI.
Results:
71% of the children had a pathological MRI. In 43% of the children with subdural bleeding could be found parenchymal lesions in the underlying cortex. All 15 children with epidural bleeding had unsuspicious findings at the former hematoma. All of the contusions were found as parenchymal residual lesions. 44% of the children had evidence of parenchymal lesions in the follow-up MRI initially and retrospectively not revealable. 16 lesions in the corpus callosum were only revealed by MRI.
Conclusion:
This study shows the higher sensitivity of magnetic resonance imaging in non-hemorrhagic parenchymal lesions and in "diffuse axonal injury". A MRI-examination is recommended in children with severe head injury, especially in patients with normal CCT and posttraumatic neurological deficits.
