Navigated Intraoperative Ultrasound in Functionally Eloquent Tumour Resection: A Descriptive Single-Centre Series Within the Modern Multimodal Neuro-Oncology Surgery Workflow

Background/Objectives: Navigated intraoperative ultrasound (N-ioUS) compensates for brain shift, but its place within a multimodal workflow alongside neuronavigation, 5-aminolevulinic acid (5-ALA) fluorescence and neurophysiological monitoring is not well defined. We describe functional and surgical outcomes in a single-centre series of functional-eloquent tumours resected with N-ioUS within such a workflow.
