Qualitative analysis of contrast-enhanced ultrasound in differential diagnosis of breast lesions

Abstract

The objective . Revelation of informative markers of qualitative analysis CEUS in the differential diagnosis of breast lesions, determination of effectiveness CEUS in the breast cancer examination. Materials and methods . The work is based on the results of a retrospective comparison ultrasound data with the histological results conducted in 145 women with breast lesions at the age of 17-71 years (average age was 45.5 years) from December 2017 until November 2018 year. Results. Statistical analysis of markers of qualitative assessment CEUS showed that more important markers in the differential diagnosis were - indicators of definition of the boundaries of lesion during CEUS (Se 79,27 Sp 63,41); the velocity of accumulation of contrast agent (Se 78,05 Sp 80,95); wash-out velocity from lesion (Se 68,29 Sp 95,24). Conclusion . Qualitative data analysis of CEUS provides to detail of breast lesions and surround tissues vascular architecture, improves differential diagnosis of breast tumors, which allows to reduce the number of additional methods of examination and biopsies, predict the volume of surgical and complex treatment.
