Purpose: To determine the difficulties in interpretation of breast ultrasound with American College of Radiology Breast Imaging Reporting and Data System (ACR BI-RADS) through survey and to find out the answers.
Materials and Methods: We made the questionnaire of 23 questions after we had made a data of the difficulties regarding the interpretation of breast ultrasound with ACR BI-RADS, from 10 dedicated breast radiologists of 8 branch hospitals of the same medical school. The survey was classified into 6 categories such as application of ACR BI-RADS(question 1-4), lexicon and interobserver variability(question 5-10), assessment category(question 11-15), ultrasound after breast surgery(question 16,17), notcategorized(question 18-21), and medical audit(question 22, 23). 1 answer was to be selected among 2 to 5 answers for multiple-choice questions, if available. Some questions were discussion question requiring each radiologist’s opinion. The questionnaire was emailed to each participant of this study and we collected the reply for 7 days. We analyzed the collected data and tried to find the most appropriate answer by review of literatures.
Results: Most inquired questions are about the lexicon and interobserver variability (6 questions) and assessment category (5 questions). Excluding 2 discussion questions, only 3(14%) basic questions show the agreement unanimously. The remained 18 questions, agreement of more than 70% (7 out of 10) is revealed in 8(38%) questions. The other 10(48%) questions show the lower agreement. Number of questions showing discrepancy between most selected answers and the literature-reviewed most appropriate one is 7. In this 7 questions, 3 are in need of correct answers and belong to the most inquired and not-categorized categories.
Conclusion: We conclude that dedicated breast radiologists have various interpreting criteria for breast ultrasound with ACR BI-RADS, with especially low understanding in ACR BI-RADS lexicon and interobserver variability and assessment category. If more precise and consistent interpretation criteria for breast ultrasound are established through the literature reviews and many studies, we could perform more effective breast ultrasound examination and interpretation
