68-Ga DOTATATE PET/MRI in the Diagnosis and Management of Somatostatin Receptor Positive CNS Tumors.
The study population consists of patients who undergo resection for somatostatin
receptor-positive (SSTR-positive) CNS tumors, focusing on meningioma, and including
esthesioneuroblastoma, hemangioblastoma, medulloblastoma, paraganglioma, pituitary adenoma,
and SSTR-positive systemic cancers metastatic to the brain, such as small cell carcinoma of
the lung. The study indication is to determine the diagnostic utility of 68Ga-DOTATATE
PET/MRI in the diagnosis and management of patients with SSTR-positive CNS tumors,
specifically whether 68Ga-DOTATATE PET/MRI demonstrates utility distinguishing between tumor
recurrence and post-treatment...
