Outcome Measures
Primary Outcomes (2)
Qualitatively measure the visual appearance of target lesion to cranial blood pool using the maximum SUV ratio to compare results from Ga-68-DOTATATE and -DOTATOC PET.
Compare visual appearance qualitatively using the maximum SUV ratio of target lesion to cranial blood pool (i.e. superior sagittal sinus reference region) of DOTATATE and DOTATOC PET scans in patients with meningioma. Based on our pilot clinical case series, the following reference regions will be evaluated: 1. Suspected meningioma; 2. Pituitary gland; 3. Superior sagittal sinus; 4. Brain parenchyma. Dynamic PET will be acquired and data will be analyzed including comparison of tissue-activity curves and Patlak analysis, as established by the PI in a pilot cohort. Extent of meningioma based on Ga-68-DOTATATE- and DOTATOC PET/CT will be compared to extent of disease as determined by MRI.
Over 12 months
Quantitatively measure the visual appearance of target lesion to cranial blood pool using the maximum SUV ratio to compare results from Ga-68-DOTATATE and -DOTATOC PET.
Compare visual appearance quantitatively using the maximum SUV ratio of target lesion to cranial blood pool (i.e. superior sagittal sinus reference region) of DOTATATE and DOTATOC PET scans in patients with meningioma. Qualitative analysis will include evaluation by board certified radiologists with expertise in nuclear medicine/ molecular imaging who will be blinded to the radiotracer injected. Quantitative analysis will include extraction of the ratio of lesion's SUVmax values/reference regions.
Over 12 months
Secondary Outcomes (4)
Compare molecular biomarker (Ki67) analysis to Ga-68-DOTATATE PET and Ga-68-DOTATOC PET by measuring biomarker histopathology (Ki67) results to the maximum SUV ratio of target lesion to cranial blood pool.
Over 12 months
Compare molecular biomarker (EGFR) analysis to Ga-68-DOTATATE PET and Ga-68-DOTATOC PET by measuring biomarker histopathology (EGFR) results to the maximum SUV ratio of target lesion to cranial blood pool.
Over 12 months
Compare molecular biomarker (progesterone receptor) analysis to Ga-68-DOTATATE PET and Ga-68-DOTATOC PET by measuring biomarker histopathology (progesterone receptor) results to the maximum SUV ratio of target lesion to cranial blood pool.
Over 12 months
Compare molecular biomarker (SSTR2 expression) analysis to Ga-68-DOTATATE PET and Ga-68-DOTATOC PET by measuring biomarker histopathology (SSTR2 expression) results to the maximum SUV ratio of target lesion to cranial blood pool.

Patients with Meningioma
EXPERIMENTALSubjects with suspected meningioma planned for surgery who meet the inclusion and exclusion criteria.
Interventions
The study intervention consists of two PET scans that will be performed using two different radiotracers, 68-Ga-DOTATATE and 68-Ga-DOTATOC. Ga-68-DOTATATE and 68-Ga-DOTATOC are PET radiotracers targeting somatostatin receptors. The study intervention consists of 2 PET scans that will be performed at least 24h apart using 68-Ga-DOTATATE and 68-Ga-DOTATOC radiotracers, in patients with suspected meningioma that are planned for subsequent surgery.

Eligibility Criteria
You may qualify if:
- Adult patients with clinically suspected meningioma
- Patients planned for surgery - undergoing preoperative workup
- No contraindications to either radiotracer
You may not qualify if:
- Age less than 18 years
- Inability to lay on the scanner table for the required period of time, e.g., due to bone pain or claustrophobia.
