Fig. 4From: Colorectal liver metastases: radiopathological correlationTypical 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)Back to article page
