To analyze the ultrasound features of Breast Imaging Reporting and Data System (BI-RADS) category 4 breast cancer
and to improve the diagnostic accuracy of atypical breast cancer by ultrasound.
Methods:
A total of 138 cases with ultrasound-diagnosed BI-RADS category 4 breast cancer in 5-year follow-up were collected and confirmed by surgery and pathology. The ultrasound classification was compared with pathological results.
Results:
Among 138 cases of BI-RADS category 4 breast cancer diagnosed by ultrasound
there were 59 classified as 4A
28 as 4B and 51 as 4C. There was no significant difference between ultrasound classification and pathological results. But the ultrasound features betw
een 4A and 4B/4C were significantly different (
P
0.05).
Conclusion:
Ultrasound could improve the diagnosis of early BI-RADS category 4 breast cancer.
