Application of SWIG for stereotactic biopsies. Stereotactic biopsies with SWIG offer rapid confirmation that abnormal tissue was biopsied. When a sample was biopsied outside the contrast-enhancing legion using neuronavigation (top row), it did not demonstrate NIR fluorescence and was normal tissue on the frozen pathology. On the contrary, when a sample was biopsied within the contrast-enhancement (bottom row), it demonstrated NIR fluorescence and pathology diagnosis was GBM. Thus, SWIG offers an affordable, rapid, and accurate adjunct to stereotactic biopsies to reduce operating length.
