Fig. 2.

Representative core with invasive tumor (core 15); 80 % cellularity estimated by author S.K. in histologic image (standard H&E staining), 75 % cellularity estimated in grayscale confocal fluorescence image (0.01 % proflavine staining), and 90 % cellularity estimated in false-colored confocal fluorescence image derived from grayscale image (0.01 % proflavine staining). The solid outlined region indicates areas of the CNB specimen that contain neoplastic tissue. The scale bar at left is 750 μm. The insets at right show a region of neoplastic tissue in the CNB specimen. The locations of the insets are indicated in each core by a square with dashed lines. The scale bar at right is 100 μm
