目的:应用磁共振动态增强(DCE-MRI)半定量参数评估子宫肌瘤射频治疗的疗效.方法:回顾性分析2015年1月—2020年4月大庆油田总医院经射频治疗的52例子宫肌瘤患者的临床资料.术前及术后行磁共振动态增强检查,测量达峰时间(time to peak,TTP)、最大浓度(maximum concentration,MAX Conc)、时间—浓度曲线下面积(area under the time concentration curve,AUC)及最大斜率(maximum slope,MAX Slope),并利用四组参数对病灶进行疗效评估.结果:TTp、MAX Conc、AUC、MAX Slope比较,差异有统计学意义(Z=-4.025、-5.929、-6.011、-5.646,P<0.05).结论:磁共振动态增强半定量参数TTp、MAX Conc、AUC、MAX Slope在术后疗效评估中具有重要意义,可作为有效的评估手段.
Value of Magnetic Resonance Dynamic Enhancement Semiquantitative Parameters in the Assessment of Uterine Fi-broids After Radiofrequency Ablation Therapy for Uterine Fibroids
Objective:To apply semi-quantitative parameters of dynamic magnetic resonance enhancement(DCE-MRI)to assess the efficacy of radiofrequency treatment of uterine fibroids.Methods:Clinical data of 52 patients with uterine fibroids treated with radiofrequency in the sample hospital from January 2015 to April 2020 were analyzed retrospectively.Magnetic resonance dy-namic enhancement was performed preoperatively and postoperatively.Time to peak(TTP),maximum concentration(MAX Conc),area under the time-concentration curve(AUC)and maximum slope(MAX Slope)were measured.The efficacy of the lesions was al-so assessed using the four sets of parameters.Results:The differences in TTp,MAX Conc,AUC,and MAX Slope were statistically significant(z=-4.025,-5.929,-6.011,-5.646,P<0.05).Conclusion:Magnetic resonance dynamic enhancement semiquantitative parameters TTp,MAX Conc,AUC,and MAX Slope have significance in the assessment of postoperative efficacy and can be used as an efficacy assessment tool.
