Figure 4.
Representative images from a 54-year-old man diagnosed with hepatocellular carcinoma. Preoperative T2 MR image shows a round tumor about 1.1*1.0 cm in the left liver (a) (arrowheads). After enhanced perfusion of this tumor under CEUS guidance (b) (arrowheads), then a laser fiber ablated the target tumor (c) (arrowheads), and immediately CEUS showed no enhanced perfusion (d) (arrowheads). During six-month follow-up after ablation, T1 (e) and substance phase MR images (f) showed the mass was successfully ablated (arrowheads).
