Research into the value of b-mode ultrasound and strain elastography ultrasound in the diagnosis of breast cancer

SUMMARY

A diagnostic test study was conducted at Bạch Mai hospital to evaluate the efficacy of Ultrasound Strain Elastography in diagnosis of breast masses.

Result: 22 patients with 24 lesions were prospectively evaluated by B-mode ultrasound and strain elastography, followed by the core biopsy. The sensitivity, specificity, positive predictive value, negative predictive value, accuracyfor the B-mode Ultrasound were 94.1%, 57.1%, 84.2%, 80%, 83,3%. Elastography combined with B-mode ultrasound improved the value in diagnosis, the sensitivity, specificity, positive predictive value, negative predictive value, accuracywere 100%, 71,4%, 89,4%, 100%, 91,7%.

Conclusion: Strain elastography can better diagnose BI-RADS 3 and 4a lesions, especially when combined with B-mode breast ultrasound, which may increase or decrease the BI-RADS level, improvethe accuracy from 83,3% to 91,4%.
