Figure 4

Region of histological features of interest for invasive lobular carcinoma, as seen in conventional H&E staining (a) and PhC \(\mu\)CT (b) with a pixel size of 4 μm. The adipose component as well as the stromal component infiltrated by lobular carcinoma, respectively, included in red and black dashed lines, are well distinguishable in both images. The scalebar is to 0.5 mm. The white spots in CT reconstructions (in correspondence of the area marked in red in panel a) are attributable to air bubbles in the paraffin at different vertical planes, primarily resulting from the sharp interface between paraffin and air.
