PURPOSE
The aim of this study was to investigate the diagnostic performance of lesion echogenicity ratios (LER) calculated by image histogram analysis for distinction of malignant and benign breast lesions.
MATERIAL AND METHODS
A total of 55 patients (mean age, 44 years) with 59 lesions were included. Ultrasound images were analyzed retrospectively.
RESULTS
Mean LER values in benign and malignant lesions were 1.63±0.41 and 3.1±0.87, respectively. The difference between LER values of benign and malignant breast lesions was statistically significant (P<.001).
CONCLUSION
LER can be used as an adjunct ultrasound parameter to differentiate between benign and malignant breast lesions.
目的
本研究旨在探讨通过图像直方图分析计算病变回声比（LER）对鉴别良恶性乳腺病变的诊断性能。
材料与方法
共纳入 55 例患者（平均年龄 44 岁）的 59 个病灶。回顾性分析超声图像。
结果
良性和恶性病变的平均 LER 值分别为 1.63±0.41 和 3.1±0.87。良性和恶性乳腺病变的 LER 值差异有统计学意义（P<.001）。
结论
LER 可作为辅助超声参数，用于鉴别良恶性乳腺病变。
