本文介绍了在肝脏射频消融（RFA）手术中使用声辐射力脉冲（ARFI）成像的临床试验的初步结果。迄今为止，已从5例独特患者的6次RFA手术中收集了数据。在消融前恶性肿瘤（平均7.5 dB，范围5.7-11.9 dB）和消融后热损伤（平均6.2 dB，范围5.1-7.5 dB）的ARFI图像中观察到大位移对比度。一般来说，ARFI图像提供了上级边界定义的结构相对于单独使用传统的超声检查。虽然还需要进一步的研究，但初步结果令人鼓舞，并证明了ARFI方法在RFA手术的许多阶段的临床应用前景。（电子邮件：bfahey04@gmail.com）（C）2008年世界医学和生物学超声联合会。
The initial results from clinical trials investigating the utility of acoustic radiation force impulse (ARFI) imaging for use with radio-frequency ablation (RFA) procedures in the liver are presented. To date, data have been collected from 6 RFA procedures in 5 unique patients. Large displacement contrast was observed in ARFI images of both pre-ablation malignancies (mean 7.5 dB, range 5.7-11.9 dB) and post-ablation thermal lesions (mean 6.2 dB, range 5.1-7.5 dB). In general, ARFI images provided superior boundary definition of structures relative to the use of conventional sonography alone. Although further investigations are required, initial results are encouraging and demonstrate the clinical promise of the ARFI method for use in many stages of RFA procedures.
