[Importance of color Doppler in diagnostics of breast diseases]

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.
