Objective:

The value of ultrasound Breast Imaging Reporting and Data System (BI-RADS) grading combined with real-time shear wave elastography (SWE) in the diagnosis of benign and malignant breast lesions.

Methods:

A total of 105 patients with breast diseases (105 breast lesions) admitted to The Fourth Peoples Hospital of Taizhou from Aug. 2017 to Dec. 2018 were selected. Preoperative lesions were graded by conventional ultraso

und BI-RADS. SWE examination was performed and shear wave velocity was measured. Pathological results were taken as the gold standard to evaluate the diagnostic significance of the combination of the two for benign and malignant breast lesions.

Results:

There were 105 patients with 105 lesions

of which 67 were benign lesions and 38 were malignant lesions. According to conventional ultrasound BI-RADS standards

37 cases were classified as 3 types

38 cases were classified as 4A

12 cases were classified as 4B

11 cases were classified as 4C

and 7 cases were classified as 5; the diagnostic sensitivity

specificity

and accuracy were 78.4%

71.2%

and 76.1%

respectively. After adding the SWE index

the BI-RADS classification was adjusted

and the results were 32 cases of type 3

30 cases of type 4A

15 cases of type 4B

18 cases of type 4C

and 10 cases of type 5; the diagnostic sensitivity

specificity

and accuracy were 85.2%

91.3%

84.2%

respectively. The difference was statistically significant (

P

＜0.05).

Conclusion:

BI-RADS classification combined with SWE can improve the accuracy of the diagnosis of benign and malignant breast lesions.
