超声弹性成像硬度评分及面积比法在术前乳腺良恶性肿块诊断价值

目的：探讨超声弹性成像硬度评分与面积比对乳腺良恶性肿块鉴别的诊断价值。方法2014年2月至2015年6月本科超声检查发现乳腺单发肿块患者68例，术前均采用超声弹性成像检查，获取病灶弹性成像图和灰阶声像图的面积比值资料，并获取术后病理结果，探讨两者在乳腺肿瘤定性方面的价值。结果恶性组43例，良性组25例；恶性组其中83．7％病灶弹性硬度4～5分，明显高于良性组12．8％（ P＜0．05）；恶性组肿块的弹性成像图与灰阶声像图面积比平均为（1．48±0．26），明显高于非恶性组肿块（1．26±0．21）（ P＜0．05）。硬度评分诊断乳腺恶性病变的灵敏度82．6％特异度84．3％，以面积比为1．3界点诊断乳腺恶性病变的灵敏度67．4％，特，异度为88．6％。结论超声弹性成像硬度评分及面积比法在鉴别乳腺肿块的良恶性具有较高的参考价值。

Hardness score and area ratio method in Breast Benign and Malignant Solid Lesions with Ultrasonic Elastography Pre-operation

Objective To investigate the value of hardness score and area ratio method in the identification of benign and malig-nant breast tumors .Methods 68 patients with single breast lesion diagnosed and given operation in Boai hospital of Zhongshan from February 2012 to June 2015 were selected .Conventional ultrasound and ultrasonic elastography were used and hardness score and area ratio were calculated .Results Among the 68 breast masses ,43 were malignant and 25 were benign .83 .7% of malignant tumors with hardness score 4-5 ,was significantly higher than 12 .8% of benign tumors(P< 0 .05) .The area ratio of malignant tumors was 1 .48 ± 0 .26 ,significantly higher than 1 .26 ± 0 .21 of benign tumors(P<0 .05) .The sensitivity and specificity of hard-ness score method was 82 .6% and 84 .3% .The sensitivity ,specificity and the best cutoff point ROC curve of area ratio method were 1 .3 ,67 .4% and 88 .6% .Conclusion Hardness score and area ratio method of ultrasonic elastography shows great clinical val-ue in the diagnosis of malignant and benign breast tumors .
