目的：评估声辐射力脉冲（ARFI）图像在评估肝细胞癌（HCC）相关射频消融中的潜在用途。方法：2010年1月至2010年6月，共38例肝细胞癌（包括复发肝细胞癌）患者接受RFA后ARFI弹性成像。检查肿瘤的亮度并测量剪切波速以量化刚度。根据亮度将肿瘤分为较亮、同色、较暗三组。采用相同的方法，对8例RFA状态后复发hcc患者的亮度与邻近RFA消融区进行比较。结果：38例hcc患者中，20例（52.6%）比周围肝硬化实质亮。另有13个（34.2%）肤色较深。其余5例（13.2%）与相邻肝实质颜色相同。所有38例rfa后病变均比既往肿瘤及周围实质颜色更深。然而，在所有8例中，复发的hcc比治疗部位更亮。结论：ARFI技术有助于鉴别诊断，在病情不明的患者中更容易发现复发的hcc。(C) 2011年白石登。版权所有。
AIM: To evaluate the potential usefulness of acoustic radiation force impulse (ARFI) images for evaluation of hepatocellular carcinomas (HCC)-associated radiofrequency ablation.METHODS: From January 2010 to June 2010, a total of 38 patients with HCC including recurred HCCs after RFA underwent ARFI elastography. The brightness of tumor was checked and the shear wave velocity was measured for the quantification of stiffness. According to the brightness, the tumors were classified as brighter, same color and darker compared with adjacent parenchyma. Using the same methods, 8 patients with recurred HCCs after RFA state were evaluated about the brightness compared with adjacent RFA ablation area.RESULTS: In the 38 patients with HCCs, 20 (52.6%) were brighter than surrounding cirrhotic parenchyma. Another 13 (34.2%) were darker. The others (5 cases, 13.2%) were seen as the same color as the adjacent liver parenchyma. Post-RFA lesions were darker than previous tumor and surrounding parenchyma in all 38 cases. However, recurred HCCs were brighter than the treated site in all 8 cases.CONCLUSION: Using ARFI technique is helpful for differential diagnosis in order to detect recurred HCCs more easily in patients with confusing status.
