Liver metastases: The role of magnetic resonance imaging

Figure 4 Liver metastases from colorectal cancer. A: EOB-magnetic resonance imaging of a 62-year-old woman demonstrates a liver lesion with hyperintensity on T2-weighted images; B: On diffusion weighted imaging the lesion appears markedly hyperintense; C: Apparent diffusion coefficient map demonstrates a peripheral hypointensity of the lesion; D: On the post-contrast arterial phase the lesion demonstrate reduced enhancement compared to the surrounding liver parenchyma with typical targetoid hypointensity; E: On the portal-venous phase the lesion remain hypovascular with targetoid appearance; F: On the hepatobiliary phase the lesion shows persistent hypoenhancement. Multiple other metastases were present in the liver parenchyma (not shown).
