Role of gadoxetic acid-enhanced liver magnetic resonance imaging in the evaluation of hepatocellular carcinoma after locoregional treatment

Figure 6 A 62-yr-old patient with infiltrative hepatocellular carcinoma with associated neoplastic portal vein thrombosis. A: High-b-value diffusion-weighted image; B: Arterial phase magnetic resonance imaging (MRI); C: Arterial phase MRI with image subtraction technique; D: Portal venous phase MRI; E and F: Hepatobiliary phase MRI; G: Pre-treatment arteriography; H: Pre-treatment cone beam computed tomography (CT); I and J: Post trans-arterial radio-embolization single photon emission computed tomography (SPECT) images. Left panel shows pre-treatment liver MRI, illustrating the cranial portion of the lesion with portal branch infiltration; whereas the right panel shows pre-treatment arteriography, the cone beam CT of the cranial portion of the lesion with the portal vein infiltration, and preoperative planning with SPECT images post administration of Tc-99m-labeled albumin macroaggregates with hyperfixation at both lesion site and portal thrombosis.
