Abstract
Objectives: To investigate whether the signal intensity (SI) ratio of residual fibroid (RF) to myometrium using Contrast-Enhanced Magnetic Resonance Imaging (CE-MRI) could predict fibroid regrowth after high-intensity focused ultrasound (HIFU) treatment.
Materials and methods: A retrospective analysis was conducted among 164 patients with uterine fibroids who underwent HIFU. To predict the RF regrowth, the SI perfusion parameters were quantified using the RF-myometrium SI ratio on CE-MRI on day 1 post-HIFU and then compared with the fibroid-myometrium SI ratio on the T2-weighted image (T2WI) and Funaki classification 1 year later. Thirty cases from another center were used as an external validation set to evaluate the performance of RF-myometrium SI ratio.
Results: The predictive performance of the RF-myometrium SI ratio on CE-MRI on day 1 post-HIFU (Area Under Curve, AUC: 0.869) was superior to that of the preoperative and postoperative fibroid-myometrium SI ratios on the T2WI (AUC: 0.724, 0.696) and Funaki classification (AUC: 0.663, 0.623). Multivariate analysis showed that the RF- myometrium SI ratio and RF thickness were independent factors. The RF-myometrium SI ratio reflects the long-term rate of re-intervention (r = 0.455, p < 0.001).
Conclusion: The RF-myometrium SI ratio on CE-MRI exhibits greater accuracy in predicting RF regrowth compared to the SI classification and the SI ratio on T2WI.
Critical relevance statement: The ratio of residual uterine fibroid to myometrial signal intensity on contrast-enhanced (CE)-MRI can reflect residual blood supply, predict regrowth of fibroids, and thus reflect long-term re-intervention rate and recovery situation of clinical high-intensity focused ultrasound (HIFU) treatment.
Key points: Contrast-enhanced (CE)-MRI can indicate the blood supply of residual uterine fibroids after high-intensity focused ultrasound (HIFU) treatment. The predictive capability of CE-MRI ratio surpasses T2WI ratio and the Funaki. Residual fibroids can serve as a measure of the long-term efficacy of HIFU.
研究目的研究对比增强磁共振成像(Contrast-Enhanced Magnetic Resonance Imaging,CE-MRI)显示的残留肌瘤(RF)与子宫肌层的信号强度(SI)比值能否预测高强度聚焦超声(HIFU)治疗后肌瘤的再生情况:对164名接受HIFU治疗的子宫肌瘤患者进行了回顾性分析。为了预测射频再生长情况,在HIFU术后第1天使用CE-MRI上的射频-子宫肌层SI比值对SI灌注参数进行量化,然后与T2加权成像(T2WI)上的肌瘤-子宫肌层SI比值以及1年后的Funaki分类进行比较。另一个中心的30个病例作为外部验证集,以评估射频-子宫肌瘤SI比值的性能:结果:HIFU术后第1天CE-MRI上的射频-子宫肌瘤SI比值的预测性能(曲线下面积,AUC:0.869)优于T2WI上的术前和术后肌瘤-子宫肌瘤SI比值(AUC:0.724,0.696)和Funaki分类(AUC:0.663,0.623)。多变量分析表明,射频-子宫肌层 SI 比值和射频厚度是独立因素。射频-子宫肌层 SI 比值反映了长期的再介入率(r = 0.455,p 结论:射频-子宫肌层 SI 比值和射频厚度是独立因素:与SI分类和T2WI上的SI比值相比,CE-MRI上的射频-子宫肌层SI比值在预测射频再生长方面表现出更高的准确性:对比增强(CE)-MRI上残留子宫肌瘤与子宫肌层信号强度的比值可反映残留血供,预测肌瘤再生,从而反映临床高强度聚焦超声(HIFU)治疗的长期再介入率和恢复情况:对比增强(CE)-MRI可显示高强度聚焦超声(HIFU)治疗后残留子宫肌瘤的血供情况。CE-MRI 比值的预测能力超过了 T2WI 比值和 Funaki。残留肌瘤可作为衡量 HIFU 长期疗效的指标。
