The breast cancer occupies one of the first places among women's malignant neoplasms. Breast cancer case rate annually increases in the majority of the countries of the world. It is very important early diagnostics and active revealing of breast pre-tumor diseases. With the purpose of definition of value of color Doppler, there were inspected 127 patients with various breast pathologies. Breast ultrasonic research, color Doppler and power Doppler allowed obtaining the essential additional data for carrying out of differential diagnostics. According to the results, concentration of vessels in a zone of tumor unit with a primary locating on periphery is characteristic for malignant formations of breast. It is, accordingly, cause of rising vascularisation of tissues of breast, and also high parameters of linear speed of blood-flow - Vmax - 0,34+/-0,05 m/s, Pi (Pulls index )- 1,42+/-0,04, Ri (Resistance index) - 0,71+/-0,02. Parameters of linear rate of a blood-flow are lower for non malignant nodal formations - Vmax from 0,14+/-0,02-0,19+/-0,02 m/s, Pi - 1,42+/-0,12-1,42+/-0,06, Ri - 0,60+/-0,02-0,62+/-0,02. In cases of weak vascularised of nodal formations the method of power Doppler was used. The maximal rate in circumflex vessels of the pathological formations in most cases did not exceed 0,25 m/s, when size of formation was up to 1,5 sm and 0,7 m/s when size of formations was more than 3 sm. At use of ultrasonic intervention combining with color Doppler and power Doppler sensitivity of diagnostics has made 93,8% and specificity - 88,6%. Proceeding from, color Doppler especially in a combination to other methods of research is the effective method, allowing increase of diagnostic accuracy. Dopplerography, allowing to visualization of blood-flow in fine vessels and even perfusion in a tissue of breast, undoubtedly, soon will occupy the one of the conducting places in diagnostics of breast diseases.
乳腺癌在女性恶性肿瘤中位居前列。世界上大多数国家的乳腺癌发病率每年都在上升。早期诊断和积极发现乳腺肿瘤前疾病非常重要。为了确定彩色多普勒的价值,对127例患有各种乳腺疾病的患者进行了检查。乳腺超声检查、彩色多普勒和能量多普勒能够为进行鉴别诊断获取重要的额外数据。结果显示,肿瘤单元区域(主要位于周边)的血管浓度是乳腺恶性肿瘤的特征。因此,这是乳腺组织血管化增加的原因,也是血流线性速度的高参数——Vmax为0.34±0.05米/秒,Pi(阻力指数)为1.42±0.04,Ri(阻力指数)为0.71±0.02。非恶性结节性病变的血流线性速度参数较低——Vmax为0.14±0.02至0.19±0.02米/秒,Pi为1.42±0.12至1.42±0.06,Ri为0.60±0.02至0.62±0.02。对于血管化较弱的结节性病变,使用了能量多普勒方法。大多数情况下,病理病变的旋支血管中的最大速度,当病变大小达1.5厘米时不超过0.25米/秒,当病变大小超过3厘米时为0.7米/秒。当使用超声介入结合彩色多普勒和能量多普勒时,诊断的敏感性为93.8%,特异性为88.6%。由此可见,彩色多普勒尤其是与其他研究方法相结合时,是一种有效的方法,能够提高诊断准确性。多普勒超声能够可视化微血管中的血流甚至乳腺组织中的灌注情况,毫无疑问,它很快将在乳腺疾病诊断中占据主导地位之一。
