Preoperative PET/MRI and radio-guided surgery using [Cu64]DOTATATE in meningioma: a feasibility study. Illustrative case.

Background: Meningiomas are the most common primary intracranial neoplasms. Gross-total resection, the primary treatment goal, is not achieved in up to 50% of patients, affecting progression-free and overall survival. The traditionally used intraoperative assessment of resection extent using the Simpson grade has recently been shown to be less accurate than postoperative MRI.
