Multimodal Neuroimaging in Image-Guided Neurosurgery: Current Applications, Clinical Challenges and Future Directions -A Narrative Review

Background Modern neurosurgery increasingly relies on individualized neuroimaging to maximize lesion resection while preserving neurological function. Conventional magnetic resonance imaging (MRI) provides detailed anatomical information but does not fully characterize cortical function, white-matter connectivity, or a...
