The goal of this study is to propose the first direct comparison of Ga-68-DOTATATE PET/CT or PET/MR and Ga-68-DOTATOC PET/CT in patients with meningioma.
The investigator is proposing a direct comparison of Ga-68-DOTATATE and -DOTATOC in a pilot cohort of patients with meningioma, and hypothesize non-inferiority of DOTATOC. This pilot study will form the basis for a subsequent prospective clinical trial and will allow us to optimize our existing imaging protocols, while developing a more cost-effective protocol. Primary Objectives: * Optimize the Ga-68-DOTATOC PET/CT protocol. * Compare Ga-68-DOTATATE PET and -DOTATOC PET/CT in patients with meningioma. Secondary Objectives • Correlate Ga-68-DOTATATE PET and -DOTATOC PET/CT with clinical an…
Inclusion Criteria: * Adult patients with clinically suspected meningioma * Patients planned for surgery - undergoing preoperative workup * No contraindications to either radiotracer Exclusion Criteria: * 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.
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.
