Extent of Gross-Total Resection and Progression-Free Survival in Patients with Brain Metastasis Can Be Predicted Using Intraoperative Second Window ICG

Researchers used delayed near-infrared imaging with high-dose indocyanine green (called “second window ICG” or “SWIG”) in the identification of brain metastases during surgery. They found that SWIG can be used to predict the extent of gross-total resection and progression-free survival in these cases.
