Advancements in Imaging and Neurosurgical Techniques for Brain Tumour Resection
Abstract: Brain tumour resection requires achieving maximal tumour removal while preserving neurological function. Recent advancements in neuroimaging and intraoperative neurosurgical technologies have substantially enhanced the precision, safety, and effectiveness of surgical interventions. This review provides a comprehensive overview of contemporary image-guided techniques, including neuronavigation, intraoperative magnetic resonance imaging (iMRI), intraoperative ultrasound (iUS), diffusion tensor imaging (DTI), fluorescence-guided surgery with sodium fluorescein, awake craniotomy, and functional brain mapping. A systematic review of studies published between 2010 and 2023 in PubMed, Scopus, and Web of Science was conducted to evaluate the clinical utility of these approaches, particularly in the management of high-grade gliomas. Current evidence indicates that combining fluorescence-guided surgery with advanced intraoperative imaging improves the extent of safe tumour resection while preserving eloquent brain regions. Nevertheless, limitations such as brain shift, imaging artifacts, and reliance on blood?brain barrier disruption remain significant challenges. Overall, the integration of advanced imaging modalities with modern neurosurgical techniques has improved surgical outcomes and holds considerable promise for advancing personalized brain tumour management.
