Balanced generation 2 (Gen2) confocal laser endomicroscope (CLE) images with different gain results in comparable image quality. (A–D) Comparison of the CLE images taken with various gain setup. Human meningioma (A,B) and glioblastoma (C,D) samples scanned ex vivo 2 h after fluorescein sodium (2-mg/kg) injection are used for analysis and illustration. Increase in the gain requires reciprocal adjustments in the brightness. Overall, the resulting images have comparable quality. (A,B) are visualized from one patient, while (C,D) are visualized from a different patient. Thick arrows signify post-processing in FIJI, which includes despeckling and maximum brightness adjustment. Scale bars are 50 μm. Used with permission from Barrow Neurological Institute, Phoenix, Arizona.
