【摘要】：目的对行高强度聚焦超声(HIFU)消融治疗的不同T2信号的子宫肌瘤行CEUS定量分析及动态血管模型(DVP)参数成像。方法对16例行HIFU治疗的单发子宫肌瘤患者,依据术前MRI T2WI信号不同分为高信号组(n=6)、等信号组(n=4)、低信号组(n=6),于HIFU治疗前行CEUS并利用SonoLiver CAP软件对其行定量分析,以子宫肌瘤与周围肌层增强水平差值为参数行DVP参数成像构建。结果 3组峰值强度、上升时间、达峰时间、平均渡越时间分别为:高信号组为(235.40±35.46)%、(22.80±3.16)s、(25.09±2.44)s、(125.78±27.63)s,等信号组为(71.97±2.43)%、(24.85±3.22)s、(32.81±3.92)s、(66.52±3.48)s,低信号组为(16.17±2.83)%、(25.42±2.66)s、(32.82±3.76)s、(64.27±3.33)s,3组间各参数比较差异均有统计学意义(P均0.05)。高信号、低信号组子宫肌瘤的DVP曲线主要表现为未消退型和负向型。结论 CEUS参数成像分析和DVP参数图可直观、动态、定量地反映不同T2信号子宫肌瘤的血流灌注差异,为HIFU治疗子宫肌瘤提供重要信息。
[Abstract]:Objective to evaluate the quantitative analysis of CEUs and dynamic vascular model DVP parameters in uterine leiomyomas with different T 2 signals treated by high intensity focused ultrasound (HIFU) ablation. Methods Sixteen patients with single uterine leiomyoma treated with HIFU were divided into high signal group (n = 6), iso-signal group (n = 4) and low signal group (n = 6) according to MRI T _ 2WI signal intensity before HIFU. CEUs were quantitatively analyzed by SonoLiver CAP before HIFU treatment. DVP parameter imaging was performed with the difference of enhancement level between uterine leiomyoma and peripheral myometrium. 缁撴灉 3缁勫嘲鍊煎己搴，
