摘要: [摘要]〓
〖HTH〗目的〖HTSS〗〖KG*2〗应用3.0T磁共振成像(magnetic resonance imaging,MRI)及弥散加权成像(diffusionweightedimaging,DWI) 评价高强度聚焦超声(high intensity focused ultrasound,HIFU) 治疗子宫肌瘤对邻近周围组织的影响。
〖HTH〗方法〖HTSS〗〖KG*2〗选择子宫肌瘤患者43例,于HIFU治疗术前及术后1 d行MRI成像检查,观察子宫周围组织(腹壁、耻骨联合、骶骨、膀胱、直肠)MRI信号的变化,并在T1WI和T2WI压脂、常规增强扫描、DWI以及通过表观弥散系数(apparent diffusion coefficient,ADC)测定其信号值。评价HIFU治疗子宫肌瘤对邻近周围组织的影响。
〖HTH〗结果〖HTSS〗〖KG*2〗子宫肌瘤HIFU术后T2WI压脂像上,耻骨联合、腹壁损伤组信号值高于术前,骶骨损伤组信号值低于术前(P<005)。耻骨联合损伤组、骶骨损伤组术后T1WI、增强扫描信号值低于术前(P<005)。耻骨联合损伤组应用b=500 s/mm2、b=1 500 s/mm2,损伤区域术后ADC值均较术前增高(P<005)。
〖HTH〗结论〖HTSS〗〖KG*2〗3.0T MRI及DWI可以显示HIFU治疗子宫肌瘤术后邻近周围组织出现的异常信号,有效评价HIFU治疗子宫肌瘤对其周围邻近组织的影响,指导临床减少或避免并发症的发生。

Abstract: [Abstract]〓Objective〖HTSS〗〓To evaluate the effects of 3.0T magnetic resonance imaging(MRI) combined with diffusion weighted imaging(DWI) on the adjacent tissues in the early postoperative period of highintensity focused ultrasound(HIFU) in uterine leiomyoma.
〖HTH〗〖WTHZ〗Methods〖HTSS〗〓Fortythree patients with hysteromyoma were selected and underwent MRI imaging at 1 d before and after HIFU treatment. We observed the tissue around the uterus(abdominal wall, pubic symphysis, sacrum, bladder and rectum) and MRI signal changes in T1WI, T2WI pressure grease, conventional enhancement scanning, DWI imaging and apparent diffusion coefficient(ADC) on the determination of the value of the signal, and to evaluate the effect of HIFU on adjacent uterine tissue.
〖HTH〗〖WTHZ〗Results〖HTSS〗〓The signal value of T2WI, pressure and lipid in HIFU after uterine fibroids was higher in the symphysis pubis and in the abdominal wall injury group than in the preoperative group. The signal value of sacral injury group was lower than that before operation(P<005). The value of T1WI and enhanced scan in the combined injury group and sacral injury group was lower than that before operation(P<005). By using b=500 s/mm2 and b=1 500 s/mm2, the ADC value of was higher in the symphysis fracture group than in the preoperative group(P<005).
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗〓3.0T MRI and DWI can show abnormal signal of surrounding tissue after HIFU treatment of uterine fibroids, evaluate effectively the influence of HIFU treatment  on the adjacent tissue, and guide clinical reduction, avoid complications.
