Fig. 4

Typical MR appearance of non-otherwise specific (NOS) adenocarcinoma liver metastases in a 55-year-old male patient with colon cancer. Fast spin echo T2-weighted image (a) shows a 50 mm lesion (arrow) in the right liver lobe with a mild hyperintense rim and a central heterogeneous area. On diffusion-weighted imaging (b 600 s/mm2) (b) the lesion has a peripheral hyperintense rim (arrow). The lesion also shows peripheral enhancement (arrowhead) on extracellular gadolinium chelate-enhanced fat-saturated gradient recall echo T1-weighted sequences obtained during the hepatic arterial phase (c). Gross pathology (d) confirmed the central necrosis of the lesion (black stars) and the predominantly peripheral tumor proliferation (arrowhead)
