改良弹性评分标准在乳腺良恶性病灶鉴别诊断中的前瞻性研究

Prospective study of improved elasticity scores in the differential diagnosis of malignant and benign breast lesions

目的探讨改良弹性评分标准在乳腺良恶性病灶鉴别诊断中的价值。方法对手术病理证实的394例患者共508个乳腺病灶进行了超声弹性成像检查前瞻性研究，分别采用改良及旧评分标准评分。结果508个病灶采用改良评分标准均可评分分类，其中82个病灶采用旧评分标准无法评分分类；采用改良及旧评分标准超声弹性成像诊断乳腺良、恶性病灶的准确性分别为88．8％和78．1％。结论改良超声弹性成像评分标准使用更为简便、准确，有助于减少不必要的穿刺活检。

Objective To explore the value of improved elasticity scores in differentiating malignant and benign breast lesions. Methods A prospective study was done in 394 patients with 508 breast lesions confirmed by pathology and the elastographic images of the lesions were evaluated by using old and improved elasticity scores respectively. Results The elastographic images of the lesions could be evaluated and classified in all patients by improved elasticity scores but could not be evaluated and classified in 82 lesions by old elasticity scores. The accuracy of ultrasonic elastography for diagnosing benign and malignant breast lesions was 88.8% and 78. 1%, respectively by old elasticity scores and improved elasticity scores. Conclusions The elastographic images of breast lesions were accurately evaluated by using improved elasticity scores, and the use of improved elasticity scores is helpful to reduce the biopsy which is not necessary.
