摘要
目的 通过磁共振成像(MRI)及超声随访探讨高强度聚焦超声(HIFU)治疗子宫肌瘤的有效性. 方法 60例经HIFU治疗的子宫肌瘤患者,术前、术后分别在MRI上表现出T1加权像(T1WI)和T2加权像(T2WI)上的信号,并分别在术后1、3、6和12个月进行超声复查,计算瘤体的均径和治疗前比较.结果 MRI显示HIFU治疗后子宫肌瘤组织表现为凝固性坏死,即在T2WI呈低、高或稍高信号,和T1WI呈低信号,超声随访显示治疗后1个月出现肌瘤缩小,3个月以后瘤体明显缩小,与治疗前相比差异有统计学意义(P<0.05).结论 MRI检查和超声随访证实HIFU治疗子宫肌瘤的确有效.
Objective To investigate the effects of high intensity focused ultrasound(HIFU)for uterine leiomyoma(ULMM) which were examined by MRI and followed up by ultrasound. Methods Sixty cases of ULMM were treated with HIFU which were studied by MRI of T1WI and T2WI imagine and were followed up by ultrasound 1,3,6 and 12 months after HIFU to compare the diamenters of the ULMM. Results After HIFU the ULMM became coaggulatire necrosis as showed on MRI by low or higher image of T2WI and lower image of T1WI. Ultrasound follow-up showed that the tumor began to shrink one month after HIFU ablation and the regression of ULMM was obvious three months after HIFU (P<0.05). Conclusions MRI examination and ultrasound follow-up confirm that the HIFU has an obvious effect on ULMM.
