Objective:

To evaluate the value of the diagnostic accuracy and detection rate of digital breast tomosynthesis (DBT)

digital mammography (DM)

and ultrasonography (US) in intraductal papilloma (IDP) of the breast.

Methods:

To retrospectivelyanalyze imaging findings from 567 cases with 696 lesions of IDP confirmed by pathology. The imaging findings were evaluated according to the Breast Imaging Reporting and Data System (B

I-RADS) of the American College of Radiology (ACR) by comparing the differences in the detection rates and diagnostic accuracies among the three techniques for all lesions.

Results:

For this study

comparison of DBT with DM

US with DBT

and US with DM gave the following results: for the detection rate

60.6%

vs

44.7%

99.0%

vs

60.6%

and 99.0%

vs

44.7%

respectively; and for diagnostic accuracy

51.3%

vs

39.4%

80.2%

vs

51.3%

and 80.2%

vs

39.4%

respectively

of IDP

and the differences were statistically significant.

Conclusion:

US is the first examination for the detection and imaging signs of the IDP and the IDP in the dense breast

but DBT has great value in the diagnosis of IDP as a new technique.
