【摘要】：目的分析子宮肌瘤高強度聚焦超聲(HIFU)術(shù)后增強型T_2*加權(quán)血管成像(ESWAN)信號的變化,探討ESWAN的應(yīng)用價值。方法 HIFU術(shù)前、后1 d對子宮肌瘤行常規(guī)MRI和ESWAN成像,測量ESWAN參數(shù)值并使用配對t檢驗進行比較。結(jié)果子宮肌瘤HIFU術(shù)前和術(shù)后的幅度值分別為1624.59±53.07和1750.13±39.81,相位值為(0.12×10~(-2)±0.81×10~(-2))Hz和(0.25×10~(-2)±0.10)Hz,R_2*值為(27.69±1.27)Hz和(24.19±1.20)Hz,T_2*值為(34.66±2.07)ms和(36.46±2.14)ms。HIFU術(shù)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)。結(jié)論 ESWAN有助于評估子宮肌瘤HIFU術(shù)后的組織學變化。
[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. 緇撴灉瀛愬鑲岀槫HIFU鏈墠鍜屾湳鍚庣殑騫呭害鍊煎垎鍒負1624.59鹵53.07鍜，
