Fig. 1From: Evaluation of fluorescence imaging with indocyanine green in hepatocellular carcinomaQuantification of fluorescence intensity in paraffin-embedded surgical specimens. Ratio is the average of fluorescence intensity at three points in the cancerous region (ROI 1, 2 and 3)/average in three points in the non-cancerous surrounding liver tissue (ROI 14, 15 and 16).
