【摘要】：目的探討子宮肌瘤的相關(guān)磁共振成像(MRI)參數(shù)在預(yù)測(cè)子宮肌瘤消融效果方面的價(jià)值。方法回顧性分析上海市徐匯區(qū)中心醫(yī)院超聲消融治療中心2012年4月至2013年12月共91例患者144個(gè)子宮肌瘤超聲消融治療的相關(guān)數(shù)據(jù),分析術(shù)前靶肌瘤的血供類型、MRI-T2WI信號(hào)強(qiáng)度比值(SIR)、信號(hào)均勻度、信號(hào)強(qiáng)度值(SI)和表觀彌散系數(shù)(ADC)與超聲消融療效的關(guān)系,設(shè)定MRI參數(shù)閾值并分組比較各組間治療后肌瘤的消融率。結(jié)果少血供和多血供類型的肌瘤平均消融率為89.4%、80.9%(P0.05);T2WI SIR1.5、≥1.5的肌瘤平均消融率分別為89.1%、83.6%(P0.05);T2WI SI200、≥200的肌瘤平均消融率分別為89.5%、81.4%(P0.05);ADC1.4×10-3 mm2/s、≥1.4×10-3 mm2/s的肌瘤平均消融率分別為88.3%、81.7%(P0.05);肌瘤為多血供伴T2WI SIR≥1.5的消融率低于多血供或少血供伴T2WI SIR1.5、少血供伴T2WI SIR≥1.5(P0.05);肌瘤為T2WI均勻高信號(hào)的消融率低于均勻低信號(hào)、不均勻高信號(hào)、不均勻低信號(hào)(P0.05)。結(jié)論子宮肌瘤的MRI參數(shù)可預(yù)測(cè)超聲消融子宮肌瘤的療效,血供豐富和T2WI均勻高信號(hào)的肌瘤超聲消融率較低。
[Abstract]:Objective to evaluate the value of magnetic resonance imaging (MRI) parameters of uterine leiomyoma in predicting ablation effect of uterine leiomyoma. Methods the data of 144 uterine leiomyoma patients treated by ultrasound ablation in Shanghai Xuhui District Central Hospital from April 2012 to December 2013 were analyzed retrospectively. To analyze the relationship between the blood supply type of target leiomyoma before operation and the effect of ultrasound ablation, the ratio of signal intensity to signal intensity ratio, signal uniformity, signal intensity value and apparent diffusion coefficient (MRI) on MRI-T2WI were analyzed. The threshold of MRI parameters was set and the ablation rate of leiomyoma after treatment was compared among groups. Results the average ablation rate of myoma with low blood supply and multiple blood supply was 89.40.The average ablation rate of SIR1.5 on T2WI of P0.05 and 鈮，
