Abstract:

【Abstract】 Objective To compare the diagnostic value between acoustic radiation farce impulse(ARFI) and contrast-enhanced ultrasonography in the differential diagnosis of breast masses. Methods Forty patients with 48 masses were examined with ARFI technique and contrast-enhanced ultrasonography. The receiver operator characteristic (ROC) curves were constructed to evaluate diagnostic value with pathological result as the golden standard. Results The area of ROC curve for ARFI and contrast-enhanced ultrasonography were in 0.862 and 0.929, respectively..There was no statistically significant difference of the diagnostic values between the two methods (P.>0.05). There were also no statistically significant differences in specificity and sensitivity between the two methods (P>0.05). Conclusion The ARFI technique and contrast-enhanced ultrasonography are useful in the differential diagnosis of breast masses.
