摘要
目的评价实时剪切波弹性成像(SWE)在乳腺组织及其病变中的组织定征能力和实用价值。方法对168例女性患者共215个病灶术前行SWE测定,以穿刺活检或手术病理为诊断金标准,获得乳腺病灶的弹性模量值;同样方法获得178例正常乳腺腺体及108例乳腺皮下脂肪的弹性模量值。结果乳腺恶性病灶(47个)的平均弹性最大值、平均值及最小值分别为(113.92±61.05)kPa、(55.68±31.65)kPa及(23.45±16.13)kPa,良性病灶(167个)的平均弹性最大值、平均值及最小值分别为(37.26±24.10)kPa、(23.45±14.73)kPa及(13.61±9.49)kPa,良恶性病灶3个弹性值比较差异均有统计学意义(P<0.01);乳腺腺病(61个病灶)的3个弹性值均高于纤维腺瘤(69个病灶,P<0.05);而纤维腺瘤的弹性值显著高于正常乳腺腺体和脂肪组织(P<0.01)。结论 SWE可直接实时检测各种组织的弹性模量,弹性量化数据的大小显示出SWE具有较高的组织定征能力和鉴别诊断价值。
Objective To evaluate the value of quantitative elastography with shear wave elastography (SWE) in the tissue characterization for patients with breast tissue and lesions.Methods SWE quantitative elastography were performed in 178 mammary glands,108 women with fatty tissue and 168 women with 215 breast lesions.The breast lesions were taken with pathologic results as reference,quantitative elasticity value of the lesions were measured.Results Pathological tests in 47 lesions showed were malignant and 167 les...
