ABSTRACT
Objective To evaluate the application of ultrasound elastography (UE) 5-point scores and ratio of traced area in diagnosis of breast diseases. Methods One hundred and thirty foure patients with 178 lesions were examined with UE. And 5-point scores were applied at first, and then the area ratios were calculated. The receiver operating characteristic (ROC) curve was established to evaluate diagnostic value. The histology results were used as the golden standard. The optimal cut-off point was calculated. Results The sensitivity, speciifcity and accuracy of 5-point scores (score≥4) were 78.8%, 93.8%and 91.0%respectively. The sensitivity, speciifcity and accuracy of ratio of traced area were 75.8%, 95.8%, 92.1%respectively. There was no signiifcant difference between these two diagnostic methods (Ρ>0.05). The cut-off of ratio of traced area was 1.45. When combining these two methods, the sensitivity, speciifcity and accuracy were 90.9%, 98.6%, 97.2%respectively. The accuracy was signiifcantly improved (Ρ<0.05). Conclusions The ratio of traced area and 5-point scores were both valuable diagnostic approaches. The combination of the two methods can improve the accuracy of diagnosis.
