Contrast-enhanced ultrasound in evaluating the curative effect of interventional therapy in patients with liver cancer

Figure 2 Ultrasound image illustrating a typical case. A: It depicts a standard instance of preablation ultrasonography using a low-frequency convex array probe. The arterial phase of the solid mass at the proximal peritoneum of hepatic S4 exhibited rapid enhancement within a brief duration, implying robust neoangiogenesis and ample blood supply, characteristic of tumor malignancy; B: High-frequency line array probe; C: Low-frequency convex array probe. They illustrate a typical postablation ultrasonography scenario. In the arterial phase, the solid mass at the proximal peritoneum of hepatic S4 displayed no enhancement, signifying a near-complete cessation of blood flow in the tumor region post-treatment without evident perfusion, indicating a favorable therapeutic outcome.
