Feasibility of Intraoperative Tracing of Meningioma Using [Cu64]DOTATATE

Patients will undergo a \[Cu64\]DOTATATE PET/MRI or PET/CT before undergoing radio- guided surgery. Patients will undergo another \[Cu64\]DOTATATE PET/MRI or PET/CT 6 weeks- 3 months after their surgery, and 6 months- 12 months after surgery.

After the subjects undergo the preoperative \[Cu64\]DOTATATE PET/MRI, subjects will undergo radio-guided surgery in which the surgeon will utilize a standard intraoperative gamma probe (Neoprobe Gamma Detection System ®) to assess primary/residual tumor detection.
