Diagnostic values of breast imaging and reporting data system and ultrasonic elastography for benign and malignant breast lesions

Objective To explore the diagnostic values of breast imaging and reporting data system (BI-RADS) and ultrasonic elastography (UE) for benign and maglinant breast lesions. Methods A total of 122 breast lesions were studied with BI-RADS and UE scoring to compare the sensitivity and specificity according to the pathologic results.Receiver operating characteristic (ROC) curves were used to assess the diagnostic value of BI-RADS, UE and combination. Results Among them, pathological examinations showed that there were 72 benign and 50 malignant cases.Statistically significant differences in specificity existed between BI-RADSlexicon (as≥4) and UE or combination (P 0.05); Statistically significant differences in sensitivity existed between BI-RADS (as≥4B) and UE or combination (P 0.05); No statistically significant differences existed between UE or combination.The area under the ROC curve was above 0.7. Conclusion Both BI-RADSand UE have a great diagnostic value for breast disease.UE is somewhat superior to BI-RADS.However, the value of combination may be more significant.
