二维彩色血流显像诊断乳腺小肿块的价值

Diagnostic value of small breast mass with B - mode and color Doppler imaging.

目的 探讨二维彩色多普勒诊断乳腺小肿块的价值。方法 60例乳腺小肿块女性病人,平均年龄51.5岁,经二维彩色多普勒检查,手术与病理证实小乳腺癌和良性小肿块各30例。彩色血流按信号丰富程度分四级:0、Ⅰ、Ⅱ、ⅢI级。结果 彩色多普勒在小乳腺癌中可探到80％动脉血流,且70％属Ⅱ、Ⅲ级。良性肿块可探到43.3％动脉血流,且10％属Ⅱ、Ⅲ级。经t检验有显著性差异(P<0.05)。结论 把二维特点、间接征象和血流动力学的改变结合起来,综合分析可提高小乳腺癌的正确诊断率。

Purpose To evaluate the value of B - mode and color Doppler imaging in diagnosis of small breast mass. Methods 60 female patients with small breast mass were detected by B - mode and color Doppler imaging. If there was blood flow in masses, the density of the signals was divided into four grades as 0, I , II ,III . Small breast cancer and benign lesion each held 30 cases, with mean age of 51.5 and all cases were confirmed with pathology. Results Arterial blood flow was found in 80 % small breast cancer and 70 % blood flow signals belonged to II and III grades; in 43.3% small benign lesion, 10% belonged to II and III grades (t test P< 0.05). Conclusion comprehensive evaluation can increase the overall accuracy in diagnosing the breast small cancer,which combined with B- mode indirect sign and hemodynamics changes of the mass.
