Figure 4. Examples of LR-M. A heterogeneous 4.6 cm liver mass shows rim APHE (arrows in A) that is incomplete, and washout that is early and marked (arrows in B), meeting the criteria for LR-M. Biopsy of this lesion showed HCC. Another LR-M liver lesion measuring 1.7 cm shows APHE (arrows in C), but early washout (arrows in D). Biopsy of this lesion showed metastatic neuroendocrine tumor.
