The aim of the present study was to prove the efficiency of Color Doppler and Spectral Doppler in evaluation and characterization of the ovarian neoplasm.
In total, 104 patients with adnexal masses were examined sonographically to evaluate for morphologic characteristics, as well as pulsatility indices (PI), and resistance indices (RI) over a period of 2 years, of which 20 were excluded as the masses were not finally proven to be adnexal, and thus 84 patients with ovarian neoplasm were retained as the study subjects. The final diagnosis was based on histopathologic confirmation.
Out of 84 cases, 44 were benign and 40 were malignant. Color Doppler showed vascularity in 97.5 % of malignant tumors in contrast to only 68.1 % of benign tumors. The present study showed that, 87.5 % of malignant tumors had PI less than 0.8 in contrast to only 4.54 % of benign tumors. Similarly, 82.5 % of malignant tumors had RI less than 0.6 in contrast to only 6.81 % of benign tumors.
Multiparameter analysis utilizing B-mode USG along with Color Doppler and Spectral Doppler is the mainstay in diagnosis of patients with ovarian tumors. A good specificity (84.1 %) and sensitivity (97.5 %) with PI and RI values of <1.0 and <0.6, respectively, was achieved with the present study which is highly significant in differentiating between malignant and benign ovarian tumours.
本研究旨在证明彩色多普勒和频谱多普勒在评估和鉴别卵巢肿瘤方面的有效性。
在两年时间里,对总共104例附件包块患者进行了超声检查,以评估其形态学特征以及搏动指数(PI)和阻力指数(RI),其中20例因包块最终未被证实为附件包块而被排除,因此保留84例卵巢肿瘤患者作为研究对象。最终诊断基于组织病理学确认。
84例病例中,44例为良性,40例为恶性。彩色多普勒显示97.5%的恶性肿瘤有血管分布,而良性肿瘤只有68.1%有血管分布。本研究表明,87.5%的恶性肿瘤PI小于0.8,而良性肿瘤只有4.54%PI小于0.8。同样,82.5%的恶性肿瘤RI小于0.6,而良性肿瘤只有6.81%RI小于0.6。
利用B型超声检查以及彩色多普勒和频谱多普勒进行多参数分析是诊断卵巢肿瘤患者的主要方法。本研究分别以PI值<1.0和RI值<0.6取得了良好的特异性(84.1%)和敏感性(97.5%),这对于鉴别恶性和良性卵巢肿瘤具有高度显著性。
