目的探讨超声造影在评价HIFU治疗肝癌近期疗效中的价值。方法利用三维超声造影和增强CT观察26例原发性肝癌的29个肿瘤病灶的影像学变化。结果高强度聚焦超声(HIFU)治疗前超声造影和增强CT检查,病灶表现为快进快出典型灌注模式者为27/29(93.1%)个和26/29(89.7%)个,二者比较差异无统计学意义(P>0.05);HIFU后超声造影和增强CT检查25/29个病灶(86.2%)表现为边界清楚的肿瘤灌注缺损,且可见边缘锐利光滑的环状增强带。结论超声造影和增强CT均可较准确地评价HIFU治疗肝癌的疗效,二者比较差异无统计学意义。超声造影是评价HIFU治疗肝癌后近期疗效的重要方法之一。
Objective To investigate the value of contrast-enhanced ultrasound (CEUS) in evaluating the short-term curative effect of HIFU in the treatment of liver cancer. Methods Three-dimensional contrast-enhanced ultrasound and enhanced CT were used to observe the imaging changes of 29 tumor lesions in 26 cases of primary hepatocellular carcinoma. Results Compared with contrast-enhanced ultrasonography and contrast-enhanced computed tomography (CT) before HIFU treatment, the rate of lesions was 27/29 (93.1%) and 26/29 (89.7%) respectively There was no significant difference between the two groups (P> 0.05). 25/29 lesions (86.2%) underwent HIFU contrast-enhanced ultrasound and enhanced CT showed a well-defined tumor perfusion defect with a sharp and smooth annular enhancement band. Conclusion Contrast-enhanced ultrasound and contrast-enhanced CT can evaluate the efficacy of HIFU in the treatment of liver cancer more accurately. There is no significant difference between the two groups. Contrast-enhanced ultrasound is one of the important methods to evaluate the short-term efficacy of HIFU in the treatment of liver cancer.
