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

Figure 3 Two-years liver magnetic resonance imaging follow-up of a 71-yr-old male with liver cirrhosis and previous subcapsular hepatocellular carcinoma in segment VIII underwent radiofrequency ablation. A: T2-spectral attenuated inversion recovery; B: High b-value diffusion weighted imaging; C: Arterial phase magnetic resonance imaging (MRI); D: Arterial phase MRI with image subtraction technique; E and F: Hepatobiliary phase MRI. Liver MRI showed recurrent hepatocellular carcinoma (8 mm) located infero-lateral to the radiofrequency scar, characterized by moderate to high signal hyperintensity in T2, hyperintensity in high b-value diffusion sequences, with arterial “wash in” and hypointensity in hepatobiliary excretion phase.
