摘要

Abstract Purpose To evaluate strain elastography as a complementary tool for characterization of lesions identified during second‐look MRI‐directed sonographic examination. Methods We reviewed 83 breast lesions evaluated with MRI, secondlook ultrasound (US) and strain elastography in 75 consecutive patients (median age, 56?years). US‐guided biopsies were performed in all cases. Results After histopathological examination, 44 lesions were benign, 38 were malignant and 1 was high‐risk. At MRI, the mean size of the lesions was 12?mm. Forty lesions (48.2%) appeared as masses, 30 (36.1%) as “non‐masses” and 13 (15.7%) as “foci.” At second‐look US examination, 56 (67.5%) appeared as masses (mean size, 7 mm) and 27 (32.5%) as non‐masses (mean size, 14?mm). At strain elastography, among the 39 malignant/high risk lesions, 5 (12.8%) had a score of 4 or 5, whereas 16 (41%) had a score of 1 and 2 (false negative). Among the 44 benign lesions, 36 (82%) had a score of 1 or 2, whereas none had a score of 5. Sensitivity and specificity of strain elastography in the diagnosis of breast cancer were 58% and 81%, respectively. Conclusion The addition of strain elastography offers no benefit in the characterization of lesions identified on second‐look US after breast MRI.(E1, 3).
