Abstract:
Objective To evaluate the value of modified ultrasound BI-RADS classification by elastography in the diagnosis of breast masses.
Methods According to the pathological results of surgery or biopsy of breast masses between January to December 2016 in Dongguan People’s Hospital Affiliated to Southern Medical University, the results of ultrasound breast imaging reporting and data system (US-BI-RADS) and modified US-BI-RADS by elastography (UE-BI-RADS) were analyzed respectively, then to compare the value of two methods in the diagnosis of breast masses.
Results The positive predictive value (PPV) of US-BI-RADS in diagnosing malignant lesions of grade 3-5 lesions was 0.86%, 6.80%, 26.04%, 71.58%, 91.25%, respectively; and of UE-BI-RADS was 0.57%, 6.67%, 31.91%, 79.31%, 96.77%, respectively. The sensitivity, specificity, Youden index and area under curve of US-BI-RADS were 82.22%, 88.43%, 0.71 and 0.919, and those of US-BI-RADS were 87.18%, 88.98%, 0.76, 0.941.
Conclusions UE-BI-RADS can improve the diagnostic value of ultrasound for breast malignant lesions. For lesions above Grade 4, it is necessary to adjust the BI-RADS after elastography.
