ANC ≥ 1.5 X 10^9/L w/o myeloid growth factor support for 7 d preceding lab assessment\n2. Hgb ≥ 9 g/dL (90 g/L); < 9 g/dL (< 90 g/L) is acceptable if Hgb is corrected to ≥ 9 g/dL (90 g/L) as by growth factor or transfusion prior to PET scan\n3. Platelet count ≥ 100 X 10^9/L w/o blood transfusions for 7 d preceding lab assessment\n4. Bilirubin ≤ 1.5 X ULN except for pts w/ documented history of Gilbert's disease\n5. ALT and AST ≤ 2.5 X ULN\n6. Alkaline phosphatase (AP) ≤ 3 X ULN\n7. Women of childbearing potential (WCBP): negative serum pregnancy test\n\n   3.

(Part 2, intracranial tumor patients ONLY) (a) Radiographical or pathological evidence of newly-diagnosed intracranial tumor that is status-pre surgical resection, or (b) Radiographical or pathological evidence of progressive/recurrent intracranial tumor, (c) Question of pseudoprogression vs. true progression on most recent standard-of-care brain MRI, or (d) Evidence on the most recent standard-of-care brain MRI scan of intracranial metastasis/metastases in a patient with known extracranial primary cancer.\n\n   6. (Part 3, GBM patients ONLY) Any patient with at least a 1cm3 contrast-enhancing lesion suspicious for GBM (either newly-diagnosed or 1st /2nd/ 3rd recurrence of GBM, molecular GBM, diffuse astrocytomas with molecular features of GBM, H3K27M midline gliomas, gliosarcomas, or any other WHO Grade IV glioma) on a standard-of-care (SOC) brain MRI scan. If the patient undergoes a biopsy or resection for GBM (either newly-diagnosed or 1st /2nd/ 3rd recurrence of GBM, molecular GBM, diffuse astrocytomas with molecular features of GBM, H3K27M midline gliomas, gliosarcomas, or any other WHO Grade IV glioma) then the remaining contrast-enhancing lesion is at least 1cm3 in size on the post-operative scan.\n\n   7. (Part 3, GBM patients ONLY) Life expectancy of ≥ 6 months.\nHealthy volunteers allowed\nMust have minimum age of 18 Years",

Patients who have implantable devices that are contra-indicated for MRI\n   4. Bleeding disorder\n   5. Any other significant co-morbid conditions that in the opinion of the Investigator would impair study participation or cooperation.\n   6.
