Figure 4
Presence, extent, and appearance of the contrast agent deposition in tissue areas of the histology presenting abnormal density (i.e., blood vessel walls, airway walls, tuberculosis lesions) in the micro-CT images. All sections are stained with haematoxylin. Borders of the tissue (first row) and lesion regions (second row) are shown by columns for: No CA) no contrast agent, AgNO3) silver contrast agent, and I2) iodinated contrast agent. Orange circles indicate the pools of the contrast agents. A difference on the background colour is also noticeable. The scale bar represents 200 um.
