Abstract
Objective
We examined whether early diffusion-weighted magnetic resonance imaging (DW-MRI) abnormalities of the brain and variation of apparent diffusion coefficient (ADC) values can provide prognostic information on clinical outcome in children following cardiac arrest (CA).
Design
Retrospective study.
Setting
A 12-bed paediatric intensive care unit (PICU).
Patients
Children aged between 1 month and 18 years who had DW-MRI with ADC measurement within the first week following CA. Neurological outcomes were assessed using the Pediatric Cerebral Performance Category Scale (PCPC). Differences between the favourable (PCPC ≤3) and unfavourable (PCPC ≥4) groups were analysed with regard to clinical data, electrophysiological patterns as well as qualitative and quantitative DW-MRI abnormalities.
Results
Twenty children with a median age of 20 months (1.5–185) and a male/female sex ratio of 1.5 underwent DW-MRI after CA with a median delay of 3 days (1–7). Aetiologies of CA were (i) asphyxia (n = 10), (ii) haemodynamic (n = 5) or (iii) unknown (n = 5). With regard to DW-MRI findings, the unfavourable outcome group (n = 8) was associated with cerebral cortex (p = 0.02) and basal ganglia (p = 0.005) lesions, with a larger number of injured brain regions (p = 0.001) and a global decrease in measured ADC signal (p = 0.008). Normal DW-MRI (n = 5) was exclusively associated with the favourable outcome group (n = 12).
Conclusion
Qualitative, topographic and quantitative analysis of early DW-MRI with ADC measurement in children following CA may provide valuable prognostic information on neurological outcomes.
