Second Window Indocyanine Green for All Nervous System Tumors

Intraoperative Molecular Imaging of Central Nervous System Tumors Using Same Day Second Window Imaging With Indocyanine Green (TumorGlow™ - CNS)

The study is being conducted to determine if a same-day, low-dose intravenous (into a vein) injection of indocyanine green (ICG) (FDA-approved dye) being detected by using an imaging system can be a useful tool in identifying and differentiating tumor tissue from normal tissues.

Inclusion Criteria:

1. Adult patients 18 years of age and older
2. Patients presenting with a nervous system tumor presumed to be resectable and at risk for local recurrence on pre-operative assessment
3. Good operative candidates, as determined by the treating physician and multidisciplinary team
4. Subjects capable of giving informed consent

Exclusion Criteria:

1. Pregnant women, as determined by urinary or serum beta hCG within 48 hours of surgery
2. Subjects with a history of iodide allergies
3. Vulnerable patient populations
4. Patients unable to participate in the consent process
