Liver metastases: The role of magnetic resonance imaging

Figure 6 Liver metastases from ileal neuroendocrine tumor. A: EOB-magnetic resonance imaging of a 55-year-old female patient shows a focal liver lesion isointense on in-phase images; B: On out-of-phase images, the lesions persist isointense compared to the healthy liver parenchyma; C: On T2-weighted images the lesion appears slightly hyperintense (orange arrow); D: Diffusion weighted imaging reveal restriction of diffusion of the lesion (orange arrow); E: Before contrast administration the lesion is isointense; F: During the post-contrast late hepatic arterial phase the lesion appears hypervascular (orange arrow); G: The lesion is isointense on the portal-venous phase; H: On the hepatobiliary phase lesion’s low signal intensity is observed (orange arrow).
