Abstract

PURPOSE
To evaluate radiology residents' performance in interpretation and comprehension of breast ultrasonographic descriptors in the Breast Imaging Reporting and Data System (BI-RADS) to suggest the adequate duration of training in breast ultrasonography.
MATERIALS AND METHODS
A total of 102 radiology residents working in the Department of Radiology were included in this study. They were asked to answer 16 questions about the ultrasonographic lexicon and 11 questions about the BI-RADS category. We analyzed the proportion of correct answers according to the radiology residents' year of training and duration of breast imaging training.
RESULTS
With respect to the duration of breast imaging training, the proportion of correct answers for lexicon descriptors ranged from 77.2% to 81.3% (p = 0.368) and the proportion of correct answers for the BI-RADS category was highest after three-four months of training compared with after one month of training (p = 0.033). The proportion of correct answers for lexicon descriptors and BI-RADS category did not differ significantly according to the year of residency training.
CONCLUSION
Radiology residents' comprehension of the BI-RADS category on breast ultrasonography was not associated with their year of residency training. Based on our findings, radiology residents' assessment of the BI-RADS category was significantly improved with three-four months of training compared with one month of training.

  Fig. 1. Transverse (A) and longitudinal (B) ultrasonographic images showing an irregular hypoechoic mass with spiculated margins. The proportion of correct answers for margin was 74.1% (60/81). The mass was confirmed as a complex sclerosing lesion. Complex sclerosing adenosis can be seen as a spiculated margin.

  Fig. 2. Transverse (A) and longitudinal (B) ultrasonographic images of an oval circumscribed hypoechoic mass showing BI-RADS category 3. The proportion of correct answers for this BI-RADS category was 38.2% (26/68). The mass was confirmed to be a fibroadenoma. BI-RADS = Breast Imaging Reporting and Data System
