Abstract

Neonatal encephalopathy (NE) is a significant global health concern. It is a leading cause of long-term neurodevelopmental impairment, with hypoxic-ischaemic perinatal brain injury being the most common underlying contributor. Although therapeutic hypothermia has reduced mortality and improved outcomes for some affected infants, many survivors experience neurodevelopmental disability, including cerebral palsy and/or deficits in cognition, behaviour, and executive functioning. Early and accurate prognostication and identification of injury severity remain a challenge due to evolving clinical signs and multiple etiologies. Magnetic resonance imaging (MRI) is the gold standard for characterizing NE-related brain injury. Diffusion-weighted imaging (DWI) enables early detection of injury, and proton magnetic resonance spectroscopy (1H-MRS), specifically the Lac/NAA peak area ratio from basal ganglia and thalamus, provides robust prognostic indicators of two-year neurodevelopmental outcomes. MRI scoring systems incorporating multiple modalities correlate well with later neurodevelopmental outcomes. Advanced imaging modalities, such as diffusion tensor imaging (DTI), arterial spin labelling (ASL), and blood oxygen level-dependent (BOLD) imaging, offer further insights into microstructural integrity, perfusion, and functional connectivity. By standardizing acquisition protocols and post-processing, MRI biomarkers can serve as reliable, early surrogate endpoints in neuroprotection trials, allowing smaller sample sizes and accelerating clinical translation. MRI and 1H-MRS integration enhances prognostication, guides clinical management, and supports informed decision-making in NE care.
