Ultrasound elasticity imaging correction and biopsy diagnosis value in BI-RADS 4 breast mass / 中国肿瘤临床

ABSTRACT

Objective:To compare the diagnostic value of strain ratio correction in ultrasound elasticity imaging and ultrasound-guided percutaneous biopsy for the diagnosis of breast imaging reporting and data system (BI-RADS) 4 breast mass. Methods:From January 2014 to June 2016 in the Affiliated Hospital of Chengde Medical College, 120 patients with breast tumor resection and preoperative BI-RADS4 of all the masses were included in this study. The diagnostic value of contrast ultrasound elastography strain ratio correction and biopsy in ultrasound-guided percutaneous biopsy was evaluated with pathology as the gold standard. Results:In the 120 cases of grade BI-RADS4 mass by ultrasound elastography after correction, 46 cases were graded BI-RADS4 without changing;59 cases were downgraded to BI-RADS3, and 15 cases were upgraded to BI-RADS5. The pathology, ultrasonic elastography strain ratio correction, biopsy diagnostic sensitivity, specificity, and accuracy were 90.7%, 81.8%, 85.5%, 88.8%, 98.5%, and 95.0%, respectively. A significant difference was found between ultrasonic elastography strain ratio correction and ultrasound-guided biopsy for the diagnosis of breast malignant mass (P0.05). Conclusion:Ultrasound-guided puncture biopsy is highly valuable in qualitative diagnosis of BI-RADS4 breast mass. After the pathological diagnosis, ultrasound elastography strain ratio has certain clinical value in BI-RADS4 guided biopsy and correction of mass classification.
