【摘要】：目的對(duì)行高強(qiáng)度聚焦超聲(HIFU)消融治療的不同T2信號(hào)的子宮肌瘤行CEUS定量分析及動(dòng)態(tài)血管模型(DVP)參數(shù)成像。方法對(duì)16例行HIFU治療的單發(fā)子宮肌瘤患者,依據(jù)術(shù)前MRI T2WI信號(hào)不同分為高信號(hào)組(n=6)、等信號(hào)組(n=4)、低信號(hào)組(n=6),于HIFU治療前行CEUS并利用SonoLiver CAP軟件對(duì)其行定量分析,以子宮肌瘤與周圍肌層增強(qiáng)水平差值為參數(shù)行DVP參數(shù)成像構(gòu)建。結(jié)果 3組峰值強(qiáng)度、上升時(shí)間、達(dá)峰時(shí)間、平均渡越時(shí)間分別為:高信號(hào)組為(235.40±35.46)%、(22.80±3.16)s、(25.09±2.44)s、(125.78±27.63)s,等信號(hào)組為(71.97±2.43)%、(24.85±3.22)s、(32.81±3.92)s、(66.52±3.48)s,低信號(hào)組為(16.17±2.83)%、(25.42±2.66)s、(32.82±3.76)s、(64.27±3.33)s,3組間各參數(shù)比較差異均有統(tǒng)計(jì)學(xué)意義(P均0.05)。高信號(hào)、低信號(hào)組子宮肌瘤的DVP曲線主要表現(xiàn)為未消退型和負(fù)向型。結(jié)論 CEUS參數(shù)成像分析和DVP參數(shù)圖可直觀、動(dòng)態(tài)、定量地反映不同T2信號(hào)子宮肌瘤的血流灌注差異,為HIFU治療子宮肌瘤提供重要信息。
[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. 緇撴灉 3緇勫嘲鍊煎己搴，
