目的探讨多种超声检查对高强度聚焦超声(HIFU)治疗子宫肌瘤的疗效评价。方法子宫肌瘤患者60例行HIFU治疗,于治疗前后及6个月后行常规二维超声、经阴道超声、彩色多普勒超声、超声造影,另行增强MRI为对照,比较其中资料完整的55例。结果常规二维超声可清晰显示子宫肌瘤位置、形态、大小、数目及内部回声特点,经阴道超声可清晰显示肌瘤边界。治疗后6个月未出现强化的肿瘤例数,彩色多普勒超声为48例(87.3%),超声造影为45例(81.8%),增强MRI为44例(80.0%)。超声造影与增强MRI结果比较无统计学差异。结论常规二维超声、经阴道超声、彩色多普勒超声均可粗略判断HIFU疗效,而超声造影可以更准确的评价其疗效。
Objective To evaluate the efficacy of multiple ultrasonography in the treatment of uterine fibroids by high intensity focused ultrasound (HIFU). Methods 60 cases of uterine fibroids patients underwent HIFU treatment before and after treatment and 6 months after the conventional two-dimensional ultrasound, transvaginal ultrasound, color Doppler ultrasound, contrast-enhanced ultrasound MRI as a control, compared with complete information 55 example. Results Conventional two-dimensional ultrasound can clearly show the location of uterine fibroids, morphology, size, number and internal echo characteristics, transvaginal ultrasound can clearly display the border of fibroids. Forty cases (87.3%) underwent color Doppler ultrasound, 45 cases (81.8%) underwent contrast-enhanced ultrasound and 44 cases (80.0%) underwent enhanced MRI. There was no significant difference between ultrasound and MRI. Conclusion Conventional two-dimensional ultrasound, transvaginal ultrasound, color Doppler ultrasound can roughly determine the efficacy of HIFU, and ultrasound can more accurately evaluate the efficacy.
