目的比较超声造影(contrast-enhanced ultrasound,CEUS)与MRI增强扫描在高强度聚焦超声(high intensive focused ultrasound,HIFU)治疗子宫肌瘤中的疗效监测作用。方法选取2013年1月—2014年12月采用HIFU治疗的179例子宫肌瘤患者(共234个肌瘤),对治疗前肌瘤体积及治疗后非灌注区肌瘤消融体积分别采用CEUS和MRI增强扫描检查。结果 CEUS和MRI增强扫描在治疗前肌瘤体积对比中差异有统计学意义(P<0.05),在治疗后非灌注区肌瘤消融体积对比中差异无统计学意义(P>0.05)。对治疗后残留两者均可有效检出。结论 CEUS和MRI增强扫描在HIFU治疗前都是治疗必须的检查,两者不可替代;两者均是治疗后疗效评价的有效方法,但CEUS比MRI增强扫描在治疗中更具灵活性、可重复性,在一定程度上可替代MRI增强扫描。
Objective To compare the efficacy of contrast-enhanced ultrasound (CEUS) and MRI enhanced MRI in the treatment of uterine fibroids by high intensity focused ultrasound (HIFU). Methods From January 2013 to December 2014, 179 patients with uterine fibroids (234 fibroids in total) treated with HIFU were enrolled in this study. CEUS and MRI were performed on the volume of myoma before treatment and the volume of myoma after non-perfusion Enhanced scan check. Results The CEUS and MRI contrast-enhanced MRI showed significant difference in the volume of fibroids before treatment (P <0.05), but there was no significant difference in the ablation volume of non-perfusion areas between the two groups after treatment (P> 0.05). Residual after treatment can be effectively detected both. Conclusions Both CEUS and MRI enhanced scans are necessary tests for treatment before HIFU treatment, both of which are irreplaceable. Both of them are effective methods for post-treatment evaluation, but CEUS is more flexible and repeatable than MRI enhanced MRI Sex, to a certain extent, can replace MRI enhanced scan.
