PCCT slices of unstained and stained cirrhotic livers and the corresponding line profiles highlighting the contrast enhancement obtained after application of the iodine-based staining protocol. (a) Overview image of the unstained cirrhotic liver. (b) Overview image of the cirrhotic liver after staining. The following anatomic structural regions could be identified and were labelled: vessel lumens (black arrows) and abnormal nodules (N) surrounded by annular fibrosis (red arrows). (c) Profile of the blue line shown in (a). (d) Profile of the red line shown in (b). Scale bar = 500 µm. Window settings have been optimized for both the unstained and stained CT images to provide the best contrast for the fibrous tissues. The improved contrast of the stained PCCT in comparison with that of the unstained PCCT images can be appreciated.
