To evaluate the ability of transvaginal Doppler examination to discriminate between different types of solid pelvic tumors, 55 women scheduled for laparotomy because of a solid pelvic mass underwent transvaginal sonographic examination, including color and spectral Doppler techniques. Arteries in the wall and core of each mass were examined. The histological diagnoses were as follows: uterine myoma (n = 28), malignant ovarian tumor (n = 19), and benign ovarian tumor (n = 8). Pulsatility index values tended to be highest in the malignant ovarian tumors, albeit with considerable overlap with respect to the other tumor types. The respective median pulsatility index values for arteries in the wall and core of the malignant ovarian tumors were 0.93 and 0.87, versus 0.65 and 0.51 in the benign ovarian tumors and 0.80 and 0.67 in the myomas. Time-averaged maximum velocity did not differ significantly among the three types of tumor. We conclude that Doppler measurement of blood flow velocity in tumor arteries does not add substantial information to the differential diagnosis between myomas and benign or malignant solid ovarian tumors.
为评估经阴道多普勒检查区分不同类型盆腔实性肿瘤的能力，对55例因盆腔实性肿块计划行剖腹手术的女性进行了经阴道超声检查，包括彩色和频谱多普勒技术。检查了每个肿块壁和中心的动脉。组织学诊断如下：子宫肌瘤（n = 28）、卵巢恶性肿瘤（n = 19）和卵巢良性肿瘤（n = 8）。卵巢恶性肿瘤的搏动指数值往往最高，尽管与其他肿瘤类型有相当大的重叠。卵巢恶性肿瘤壁和中心动脉各自的搏动指数中值分别为0.93和0.87，而卵巢良性肿瘤为0.65和0.51，子宫肌瘤为0.80和0.67。三种肿瘤类型之间的时间平均最大速度无显著差异。我们得出结论，肿瘤动脉血流速度的多普勒测量对子宫肌瘤与卵巢良性或恶性实性肿瘤的鉴别诊断没有增加实质性信息。
