彩色多谱勒能量图对子宫腺肌瘤与子宫肌瘤的诊断

Diagnosis of adenomyoma and uterine myoma with color doppler energy

目的 :探讨子宫腺肌瘤与子宫肌瘤在彩色多谱勒能量图上表现 ,为其鉴别诊断提供途径。方法 :观察子宫螺旋动脉血流平均积分 ,瘤体血供类型 ,频谱阻力指数。结果 :子宫腺肌瘤螺旋动脉血流平均积分在 7 8左右 ;64 42 %瘤体为棒状血流、低速高阻、RI 0 78。子宫肌瘤螺旋动脉血流平均积分在 3 4左右 ;66 7%瘤体为网络状血流、高速低阻、RI 0 62。结论 :彩色多谱勒能量图能清楚地显示子宫螺旋动脉血流积分 ,瘤体血管网 ,为子宫腺肌瘤与肌瘤鉴别诊断奠定了基础。

Objective:To search a way of distinguishing the adenomyoma from the uterine myoma.Varying natures of them were studied with the color doppler energy (CDE).Methods:The indexes observed are the blood average integral (BAI),the blood supply type (BST) in tumors and the resistance index (RI) of frequency spectrum.Results:The differences (P<0 05) of the indexes above were observed between the adenomyoma(the BAI being about 7 8;the BST (64 42% tumors) being club-shaped;the characters of blood flow being low-speed and highresistance;the RI being 0 78),and the uterine myoma(the BAI being about 3 4;the BST(66 7% tumors)being web-shaped;the characters of blood flow being high-speed and low-resistance;RI being 0 62).Conclusions:The CDE can clearly display the BAI and the BST of the tumors,and provide a new method to distinguish the adenomyoma from the uterine myoma.
