能量多普勒和三维血管重建在乳腺肿瘤诊断中的应用研究

目的:研究乳腺肿块能量多普勒显像和三维血管重建血流灌注及形态特征的变化。方法:171例乳腺肿块,选用能量多普勒和三维血管重建对照,观察血流程度变化、血流形态特征,定量分析彩色血流灌注面积。结果:三维血管重建显示乳腺癌和良性肿块血流信号比能量多普勒有显著增强效果,两者差异有显著性(P<0.05)。乳腺癌灌注面积显著大于良性肿块,两者差异有显著性(P<0.05)。结论:三维血管重建能有效增强乳腺肿块的血流信号,能量多普勒和三维血管重建对照能显著提高乳腺肿瘤鉴别诊断的价值。

Clinical evaluation of power Doppler and Three- Dimensional Reconstruction in diagnosing of Breast masses

Objective: To study the characteristics of power Doppler and Three - Dimensional Reconstruction in blood flow fill and signal in breast masses. Methods: 171 patients with breast mass were performed by power Doppler and Three -Dimensional Data Marasrment System. Patterns of vascular, color flow fill pixel density and quantitative blood flow fill were analyzed. Results: Through Three-Dimensional Reconstruction and power Doppler contrast, there was greater blood enhancement in breast cancer group than in benign group. The correlation between benign and breast cancer lesions was statistically significant ( P <0.05). Colour blood flow fill was greater in breast cancer group than in benign group ( P < 0.05,). Conclusion: Three-Dimensional Reconstruction provides significant ? improvement of blood flow signal in breast lesion. Contrast - enhanced and power Doppler and Three-Dimensional Reconstruction are valuable for differentiating breast masses.
