目的：探讨对比增强三维能量多普勒超声在鉴别良恶性附件病变中的潜在价值。方法：对45例经阴道B模式和/或彩色多普勒超声检查的不确定恶性的复杂附件病变患者在注射对比剂前后进行三维能量多普勒超声检查。穿透型和混合型提示附件恶性肿瘤。结果：卵巢恶性肿瘤12例，良性附件病变33例。在12例卵巢癌中，7例（58.3%）在非增强三维能量多普勒超声检查中显示血管分布，提示恶性肿瘤。在注射造影剂后，在所有卵巢恶性肿瘤病例中检测到穿透性血管模式和/或混合穿透性和外周模式。一个囊腺纤维瘤显示穿透血管在初始扫描，而两个良性病变（纤维瘤和囊腺纤维瘤）被误诊为恶性对比增强，三维能量多普勒超声。三维能量多普勒超声造影剂的使用显示的诊断效率（95.6%）是上级的非增强三维能量多普勒超声（86.7%）。结论：对比增强，三维能量多普勒超声检查提供了更好的显示肿瘤的血管在复杂的附件肿块。如果与三维形态学超声评估一起使用，增强三维能量多普勒成像可以准确区分良性和恶性附件病变。（《妇产科》，2000年;96：452-8。(C)2000年由美国妇产科医师学会。
Objective: To investigate the potential usefulness of contrast-enhanced, three-dimensional power Doppler sonography in the differentiation of benign and malignant adnexal lesions.Methods: A total of 45 patients with complex adnexal lesions of uncertain malignancy at transvaginal B mode and/or color Doppler sonography were prospectively evaluated with three-dimensional power Doppler sonography before and after injection of contrast agent. Presence of a penetrating pattern and a mixed penetrating and peripheral pattern suggested adnexal malignancy. All the results were compared with histopathology.Results: There were 12 cases of ovarian malignancy and 33 benign adnexal lesions. Of the 12 ovarian cancers, seven (58.3%) showed vascular distribution suggestive of malignancy at nonenhanced three-dimensional power Doppler sonography. After injection of contrast agent, a penetrating vascular pattern and/or a mixed penetrating and peripheral pattern were detected in all cases of ovarian malignancy. One cystadenofibroma demonstrated penetrating vessels at initial scan, whereas two benign lesions (fibroma and cystadenofibroma) were misdiagnosed as malignant at contrast-enhanced, three-dimensional power Doppler sonography. The use of a contrast agent with three-dimensional power Doppler sonography showed diagnostic efficiency (95.6%) that was superior to that of nonenhanced three-dimensional power Doppler sonography (86.7%).Conclusion: Contrast-enhanced, three-dimensional power Doppler sonography provides better visualization of tumor vascularity in complex adnexal masses. If used together with three-dimensional morphologic ultrasound assessment, enhanced three-dimensional power Doppler imaging might precisely discriminate benign from malignant adnexal lesions.
