ISUOG 2014：三维重建多普勒血管造影(3D-PDA)技术在子宫附件肿物鉴别诊断的应用价值

3D-PDA血管造影诊断价值
关注

在第24届世界妇产科学超声大会上，西班牙国潘普洛纳市纳瓦拉大学妇产科J. Alcazar 和意大利卡利亚里大学妇产科S. Guerriero等学者报告了三维重建多普勒血管造影(3D-PDA)在子宫附件肿物鉴别诊断方面的应用价值。 该研究为一项前瞻性研究(2009年1月- 2013年12月)，收集这期间所有诊断为持续子宫附件肿物并预计行手术的患者。所有入选者均行经阴道或经腹超声评估。先使用

在第24届世界妇产科学超声大会上，西班牙国潘普洛纳市纳瓦拉大学妇产科J. Alcazar 和意大利卡利亚里大学妇产科S. Guerriero等学者报告了三维重建多普勒血管造影(3D-PDA)在子宫附件肿物鉴别诊断方面的应用价值。

该研究为一项前瞻性研究(2009年1月- 2013年12月)，收集这期间所有诊断为持续子宫附件肿物并预计行手术的患者。所有入选者均行经阴道或经腹超声评估。先使用B超“图形识别”进行形态学评估。良性图形病变可认为是恶性肿瘤的风险低，而实性成分肿瘤的风险高,有腹水和/或癌症迹象可认为是高风险,在这种情况下不再行进一步的检查。实性肿瘤但没有腹水或癌症迹象可认为是恶性肿瘤风险中等。使用二维多普勒超声(2D-PDA)评估肿瘤血管形成情况进而评估这些病灶。无血流或周围血流的病灶可认为是良性的,并不再行进一步的检查,而中央血流丰富的肿瘤可认为是恶性肿瘤。后一组再行3D-PDA评估。 VI是1-cc单位内肿瘤最多血管化面积。一个VI > 19.000%认为是恶性肿瘤。组织学诊断是金标准。计算每种方法的灵敏度和特异度并比较。

结果发现，367名女性患者(平均年龄45.8岁)的367块肿物,86块肿物是恶性的,281块是良性的。每种方法的灵敏度和特异度(见表格1)。

作者由此得出结论，增加2D-PDA显著提高了特异度而灵敏度仍保持较高。增加3D-PDA 未得到额外的信息,且未提高诊断性。
