彩色多普勒能量图对卵巢肿瘤血流的研究

目的应用彩色多普勒能量图观察卵巢肿瘤的血流特征，以探讨其临床价值。材料与方法超声检查265例卵巢肿瘤患者293个病灶，所有病例均经手术获病理组织学证实。结果本组92.9％的卵巢癌显示肿瘤内血流，其中81.9％血流呈弥散分布。46.7％的卵巢良性肿瘤无血流显示，47.2％为包膜周边点状、带状单支规则血流。良恶性卵巢病灶的血流显示比较，相差极显著(P＜0.01)。结论彩色多普勒能量图能够直观地描述卵巢肿物的灌流状态，对于卵巢良恶性肿瘤的鉴别诊断有重要的参考价值。

Color Doppler Energy in Detecting Flow Characteristics of Ovarian Masses

Purpose: To investigate the clinical value of color Doppler energy (CDE) in detecting the blood flow characteristics of ovarian tumor. Materials and Methods: A total of 265 cases (293 lesions) with ovarian tumor were examined using CDE and the diagnosis of all cases were confirmed by postoperative histopathology. Results: It was showed that 92.9% malignant ovarian masses had centrally located vascularity and 81.9% had diffuse vascular arrangment. Benign Ovarian tumor, on the other hand, showed no color flow in 46.7% and peripherally located regular spotty or bandy single vascularity in 47.2%. There was a significant difference between benign and malignant ovarian lesions (P<0.01). Conclusion: CDE can visually depict the vascularity of ovarian masses and is thus valuable in differentiating malignant ovarian tumors from benign.
