摘要
目的应用超声造影与动态增强磁共振成像(DCE-MRI)观察经皮穿刺微波消融治疗局限性子宫腺肌病消融治疗的效果并进行分析。方法选取2013年1月至2016年7月于山东省聊城市肿瘤防治院行经皮微波消融治疗的单发局限性子宫腺肌病患者42例,术前及术后1~2 d分别进行静脉超声造影和DCE-MRI检查,观察及子宫腺肌病及病灶消融治疗的效果。结果微波消融治疗后,超声造影及DCE-MRI显示42例局限性子宫腺肌病消融灶无造影剂增强,且平均消融率均达90%以上。其中超声造影显示微波消融病灶内无造影剂灌注,消融体积及病灶消融率分别为(49.0±29.5)cm^3、(91.6±7.1)%;DCE-MRI显示消融灶内无增强区,消融体积及病灶消融率分别为(49.4±29.9)cm^3、(91.9±6.7)%。结果显示微波治疗局限性子宫腺肌病效果好,且超声造影与DCE-MRI观察的消融率一致性相近。结论超声造影对微波消融治疗局限性子宫腺肌病消融率的评价较准确,与DCE-MRI评价消融率一致性较好,对造影显示消融不完全的病灶可即刻补充消融。
Objective To observe and analyze the therapeutic effect of focal uterine adenomyosis treated with percutaneous microwave ablation by contrast-enhanced ultrasound and dynamic contrast enhanced MRI（DCE-MRI）. Methods From January 2013 to July 2016, 42 patients with focal uterine adenomyosis voluntarily underwent percutaneous microwave ablation in the tumor hospital of Liaocheng. Contrast-enhanced ultrasound and DCE-MRI were performed before and after percutaneous microwave ablation. The therapeutic effects of percutaneous microwave ablation in treatment of uterine adenomyosis lesions were observed. Results After percutaneous microwave ablation of the 42 cases, the ablated zone showed no enhancement with contrast-enhanced ultrasound and DCE-MRI. Contrast-enhanced ultrasound showed that the volume and ablation rate of ablated zone were（49.0±29.5） cm^3 and（91.6±7.1）%, and that of DCE-MRI were（49.4±29.9）cm^3 and（91.9±6.7）%, respectively. The results showed that percutaneous microwave ablation could cure focal uterine adenomyosis at the rate over 90%. Contrast-enhanced ultrasound and DCE-MRI are in accordance in observing the ablation rate. Conclusions Contrast-enhanced ultrasound can accurately show the ablation rate of focal uterine adenomyosis treated with percutaneous microwave ablation, which is quite consistent with DCE-MRI. Contrast-enhanced ultrasound has its advantages such as identifying the lesions which need immiedately supplemental ablation.
