| 目的 探讨超声背向散射积分(IBS)在肝癌射频或微波消融治疗疗效评价中的应用价值。方法 43个肝脏肿瘤病灶,在微波或射频消融治疗前后,分别测定肿瘤及消融区的IBS值,比较治疗前后的IBS值变化,并以增强CT/MRI检查作为对照。结果 肿瘤消融后IBS值明显大于消融前,与增强CT/MRI确定的范围有良好的相关性。结论 通过观察IBS值的变化,超声背向散射积分为肝脏肿瘤消融治疗疗效评估提供了一种无创的量化检查方法。 |

| Objective To evaluate the role of ultrasonic integrated backscatter (IBS) in assessing the therapeutic response to percutaneous radiofrequency and microwave ablation in patients with hepatic carcinoma. Methods Forty-three liver tumor lesions were evaluated with ultrasonic IBS before and after the treatment of microwave or radiofrequency ablation. The IBS and its changes in the tumors and the regions of interest were examined and compared before and after the treatment. The results of ultrasonic IBS were compared with those of contrast-enhanced CT or contrast-enhanced MRI. Results The values of ultrasonic IBS showed significant difference before and after the ablation. The IBS was also in correlation with the contrast-enhanced CT and/or contrast-enhanced MRI. Conclusion The IBS heralds a new method of noninvasive quantitative measurement in the assessment of therapeutic response to microwave or radiofrequency ablation of hepatic carcinoma. |
