This phase I trial studies how well gallium Ga 68-DOTATATE positron emission tomography (PET)/computed tomography (CT) works in predicting tumor growth in patients with meningiomas. Giving Gallium Ga 68-DOTATATE before PET/CT scan may work better in predicting tumor growth in patients with meningiomas.



I. To assess the ability of imaging with gallium Ga 68-DOTATATE (68Ga-DOTATATE) positron emission tomography/computed tomography (PET/CT).

II. To assess a metabolic response to radiation therapy in meningiomas as measured by a reduction in the tumor to background ratio of the maximum standardized uptake values (SUV) of the tumor compared to background brain parenchyma.


Patients receive gallium Ga 68-DOTATATE intravenously (IV) over a few minutes and, after 60 minutes, undergo a PET/CT scan over 5-10 minutes 14 days before starting scheduled radiation therapy and 6 weeks after completion of radiation treatment.
