Histograms of size distribution of pathologically confirmed colorectal liver metastasis nodules.
Nodule size refers to that recorded in pathology reports. Dark and gray bars represent nodules detected (true positives) and undetected (false negatives) at preoperative CT, respectively. Fourteen nodules were not included in the histograms as their sizes were missing in the pathology reports. (a) 447 nodules from 228 liver resections. (b) Subgroup of 331 nodules from 163 resections following gadoxetic acid-enhanced MR imaging. (c) Subgroup of 116 nodules from 65 resections without gadoxetic acid-enhanced MR imaging.

(a) Gadoxetic acid-enhanced transverse T1-weighted MR image during the hepatobiliary phase shows a small nodule (arrow) in segment 4. (b) The nodule (arrow) is not clearly seen at contrast-enhanced transverse CT image. (c) The nodule (arrow) measured 5 mm and was confirmed to be CRLM.
