【摘要】：目的分析子宫肌瘤高强度聚焦超声(HIFU)术后增强型T_2*加权血管成像(ESWAN)信号的变化,探讨ESWAN的应用价值。方法 HIFU术前、后1 d对子宫肌瘤行常规MRI和ESWAN成像,测量ESWAN参数值并使用配对t检验进行比较。结果子宫肌瘤HIFU术前和术后的幅度值分别为1624.59±53.07和1750.13±39.81,相位值为(0.12×10~(-2)±0.81×10~(-2))Hz和(0.25×10~(-2)±0.10)Hz,R_2*值为(27.69±1.27)Hz和(24.19±1.20)Hz,T_2*值为(34.66±2.07)ms和(36.46±2.14)ms。HIFU术后,幅度值、相位值和T_2*值升高(P=0.04、P=0.91和P=0.45),R_2*值降低(P=0.02)。结论 ESWAN有助于评估子宫肌瘤HIFU术后的组织学变化。
[Abstract]:Objective to analyze the changes of enhanced T 2 * weighted Angiography (ESWAN) signal after high intensity focused ultrasound (HIFU) for uterine leiomyoma and to explore the value of ESWAN. Methods conventional MRI and ESWAN were performed before and 1 day after HIFU. The parameters of ESWAN were measured and compared with paired t test. 缁撴灉瀛愬��鑲岀槫HIFU鏈�鍓嶅拰鏈�鍚庣殑骞呭害鍊煎垎鍒�涓�1624.59卤53.07鍜，
