【摘要】：目的：探討治療前子宮肌瘤MRI參數(shù)對(duì)預(yù)測(cè)超聲消融治療子宮肌瘤消融療效的價(jià)值。 資料和方法：回顧性分析中國(guó)科學(xué)院上海臨床中心/上海市徐匯區(qū)中心醫(yī)院影像科超聲消融治療中心2012年4月至2013年12月94例患者152個(gè)子宮肌瘤進(jìn)行超聲引導(dǎo)HIFU消融治療的資料數(shù)據(jù)，通過對(duì)治療前靶肌瘤的MRI T2信號(hào)強(qiáng)度值、T2信號(hào)強(qiáng)度比值及其信號(hào)均勻度、彌散加權(quán)成像ADC值和血供類型進(jìn)行分析，評(píng)估磁共振參數(shù)數(shù)值和超聲消融治療效果的關(guān)系，設(shè)定其閾值并分組，，比較分析各組與治療后肌瘤消融率的關(guān)系。 結(jié)果：T2信號(hào)強(qiáng)度閾值為200，≥200和＜200的肌瘤的平均消融率分別為81.3±16.8%、90±13.7%（P＜0.05）；T2信號(hào)強(qiáng)度比值的閾值為1.5，≥1.5和＜1.5肌瘤的平均消融率分別為83.6±17.2%、89.7±13.3%（P＜0.05）；擴(kuò)散加權(quán)成像ADC值的閾值為1.4×10-3mm2/s，其≥1.4×10-3mm2/s和＜1.4×10-3mm2/s肌瘤的平均消融率分別為81.7±18.4%、88.3±14.3%（P＜0.05）。血供豐富、少血供類型肌瘤的平均消融率分別為80.8±18.8%、89.8±12.8%（P＜0.05）；血供豐富類型伴T2信號(hào)強(qiáng)度比值≥1.5肌瘤的平均消融率低于少血供類型伴T2信號(hào)強(qiáng)度比值＜1.5、少血供類型伴T2信號(hào)比值≥1.5、血供豐富類型伴T2信號(hào)比值＜1.5的肌瘤（P＜0.05）；T2均勻高信號(hào)肌瘤的平均消融率低于T2不均勻高信號(hào)、T2均勻低信號(hào)、T2不均勻低信號(hào)的肌瘤（P＜0.05）。 結(jié)論：T2信號(hào)及其均勻度、ADC值和血供類型磁共振影像參數(shù)可預(yù)測(cè)聚焦超聲治療子宮肌瘤的消融療效，T2均勻高信號(hào)和血供豐富的肌瘤超聲消融率較低。
[Abstract]:Objective: to evaluate the value of MRI parameters in predicting the effect of ultrasound ablation on uterine leiomyoma before treatment. Materials and methods: a retrospective analysis of 152 uterine leiomyomas with ultrasound guided HIFU was performed in 94 patients with uterine leiomyoma from April 2012 to December 2013 in Shanghai Clinical Center of Chinese Academy of Sciences / Center Hospital of Xuhui District of Shanghai. Data on ablation treatment, By analyzing the MRI T2 signal intensity ratio and signal uniformity, diffusion-weighted imaging ADC value and blood supply type of target leiomyoma before treatment, the relationship between magnetic resonance parameters and the effect of ultrasound ablation was evaluated. The relationship between each group and the ablation rate of leiomyoma after treatment was compared and analyzed. Results the mean ablation rate of myoma with T 2 signal intensity threshold of 200, 鈮
