Figure 1: Comparative identification of tumor foci under brightfield and fluorescence laparoscopy. (a) OV100 open image from a representative mouse. View of left upper quadrant in a mouse specimen under FL (b–d) and BL (e–g). The green fluorescence of the metastatic lesions are unmistakable under FL, whereas under BL the tumor foci resembled normal tissue and were not identifiable. BL: brightfield laparoscopy; FL: fluorescence laparoscopy [1].
