Abstract：Objective:To explore the impact of MR T2WI high signal rim sign(T2-rim sign)on the 1-year therapeutic respons-es of high intensity focused ultrasound(HIFU)in the treatment of uterine fibroid.Methods:A retrospective study was conducted in 406 patients treated with HIFU from October 2018 to October 2023 in the First People's Hospital of Liangshan Yi Autonomous Prefecture and Nanchong Central Hospital.According to the exist images of preoperative MR T2WI T2-rim sign,the patients were divided into T2-rim sign group(94 patients)and no T2-rim sign group(312 patients).Uterine volume,uterine fibroids volume,symptoms severity score(SSS)and uterine fibroid symptoms quality of life questionnaire(UFS-QOL)score of two groups were com-pared.And adverse reactions and complications were analyzed.Results:3-month follow-up after the operation,there were statisti-cally significant differences in uterine volume,fibroid volume,and UFS-QOL score between the two groups(Z=-4.692,-8.361,-2.254;P＜0.05).No serious adverse reactions or complications occurred in either group.Conclusion:T2-rim sign has no significant impact on the safety and efficacy of HIFU treatment on fibroids.1 year after HIFU surgery,T2-rim sign group are satisfied with the clinical efficacy.
