摘　　要：目的探讨超声和MRI图像(US-MRI)配准融合技术在高强度聚焦超声(HIFU)消融子宫肌瘤中的价值。方法评估78例子宫肌瘤患者的80组US-MRI图像的配准与融合效果;记录并分析用于指导不同配准融合操作的解剖标记部位和效果。结果以子宫的边界为标志配准同一子宫平面,与配准前比较,图像清晰度评分显著增加(P=0.004);以子宫肌瘤的边界为标志配准同一子宫肌瘤平面,与配准前比较,图像清晰度评分显著增加(P<0.001);以耻骨边界为标志能配准同一耻骨平面;以骶岬为标志点能配准骶尾骨。结论 US-MRI配准技术可有效提高HIFU消融子宫肌瘤的可视化空间。Objective To explore the value of the registration and fusion technique of ultrasound image and magnetic resonance image（US-MRI）in high-intensity focused ultrasound（HIFU）ablation for uterine fibroids.Methods The effect of registration and fusion in 80 groups of images from 78 patients with symptomatic uterine fibroids was evaluated.The anatomic sites and effects of different registration and fusion operations were recorded and analyzed.Results Taking the boundaries of the uterus as a sign to register the same plane of uterine,the registration clarity of the images significantly increased than that of the images before registration（P=0.004）.While taking the boundaries of the fibroids as a sign to register the same plane of fibroids,the registration clarity significantly increased than that of the images before registration（P〈0.001）.The boundary of the pubic bone was taken as a sign to match the same plane of the pubic bone,and the sacral promontory was taken as a sign to match the sacrococcyx.Conclusion US-MRI registration technique can effectively improve the visualization space of HIFU ablation for uterine fibroids.
