Applications of ultrasound elastography in diagnosis of breast tiny substantive lesions / 中国医师进修杂志

ABSTRACT

Objective To analyze the clinical value of ultrasound elastography (UE) in qualitative diagnosis of breast tiny (≤ 10 mm) substantive lesions.Methods The clinical UE examination data of recent clinical pathology diagnosis of 82 cases of breast tiny lesions were analyzed retrospectively,and compared with pathology results for statistical analysis.Results With the lesions nature was different,the UE elasticity score of breast parenchymal lesions wasdifferent,the UE overall detection rate of breast small lesions was 93.7％ (89/95).Four points 1 lesion misdiagnosed,pathologic diagnosis of mammary gland fibroma and calcification.Three points 5 lesions misdiagnosed,pathological diagnosis were 1 of invasive ductal carcinoma,2 of intraductal carcinoma in situ,2 of invasive lobular carcinoma.The detection rate of tiny breast cancer was 80.0％ (20/25).There was no significant difference between UE and the pathological diagnosis (P＞ 0.05).Elastic strain rate in the tiny benign and malignant breast lesions had significant difference (P ＜ 0.05).Conclusion UE and real-time strain techniques have larger clinical diagnosis value in breast tiny substantive lesions,and a certain complementary role for the lesions which are difficult to diagnose.
