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

Figure 7 Post-trans-arterial radio-embolization images in the patient mentioned in Figure 6. A: T2-spectral attenuated inversion recovery; B: High b-value diffusion weighted imaging; C: Apparent diffusion coefficient (ADC) map; D: Arterial phase magnetic resonance imaging (MRI); E: Arterial phase MRI with image subtraction technique; F: Hepatobiliary phase (HBP) MRI; G: T2-spectral attenuated inversion recovery; H: High b-value diffusion weighted imaging; I: ADC map; J: Arterial phase MRI; K: Arterial phase MRI with image subtraction technique; L: HBP MRI. The liver MRIs reveal almost no signal restriction in DWI and no enhancement in dynamic study in the caudal portion of the lesion (left panel) which are suggestive of a good outcome. Whereas in the cranial infiltrating part of the lesion (right panel) at portal branch level, the high signal in DWI with arterial enhancement is suspected for residual disease.
