Filtered tomographic slices of a metastasis of a low-grade adenocarcinoma in a steatotic liver filtered with the 3D bilateral filter.

<p>Conventional absorption-based (A, D) and phase-contrast (B, E) CT images of the liver specimen in two different planes. H&E stain (C) corresponds to image A and B, respectively. (F) shows the histogram of the filtered absorption image (top) and the filtered phase-contrast image (bottom) with red dashed lines marking the window level in the shown slices.
