Images of a 58-year-old patient with a small HCC (8.8 mm) in the caudate lobe (a; T1WI dashed circle). First, with the guidance of MR, the probe was accurately inserted into the target lesion to finish the ablation procedure (b, c; T1WI). After the treatment, the thermal-induced damage zone estimated as hyperintensity on the T1 high signal range completely covers the tumor after ablation d. Then, a typical “target sign” is clearly shown in the ablated area of T1WI d, e, and a low point appears in T2WI immediately after MWA f; dashed circle)
