超声弹性成像对乳腺疾病的诊断价值

【目的】探讨超声弹性成像对乳腺疾病的诊断价值。【方法】对照病理结果,分析32例(36个病灶)乳腺病变的超声弹性图像,对乳腺病灶的弹性成像硬度进行分级;测量弹性模式和二维模式下病灶面积,计算二者比值。【结果】(1)超声弹性成像显示,良性病变弹性分级多为0-II级(19/22),而恶性病变弹性分级多为III-V级(12/14)。(2)诊断乳腺恶性病灶的灵敏度为85.7%,特异度为86.4%;乳腺恶性病变的弹性图像面积(20.6±43.7)与二维图像面积(15.2±34.8)相比显著增加,差别有统计学意义(P<0.05)。(3)乳腺恶性病变弹性图像与二维图像面积比(1.97±0.49)与良性病变(1.23±0.06)相比显著增加,差别有统计学意义(P<0.05)。【结论】超声弹性成像能客观的评价乳腺肿块的相对弹性硬度,对鉴别乳腺肿块的良恶性有较高的诊断价值。

Application of ultrasonic elastography in the diagnosis of breast disease

[ Objective ] To investigate the value of ultrasonic elastography in the diagnosis of breast disease. [ Methods ] A total of 32 patients of breast disease with 36 lesions were analyzed by ultrasonic elastograms and gray-scale uhrasonography methods. The rigidity of all lesions were analyzed in elastography mode, the areas of lesions were measured in gray-scale uhrasonography and ultrasonic elastography respectively and meanwhile the ratio was calculated. All the results were contrasted with the pathological types. [ Results] （1）The ultrasonic elastograms ： most of the benign lesions were O- lI grade （19/22, about 86.4% ）, while most of the malignant lesions were III-V grade （12/14, about 85.7% ）. （2）The areas of malignant lesions in elastography （20.6 ±43.7） were significantly increased as compared with those in gray-scale uhrasonography （15.2±34.8） （P 〈 0.05 ）. （3）The area ratio of malignant group （1.97±0.49）in the two modes was larger than that of benign group （1.23 ± 0.06） （P 〈 0.05）. [ Conclusion ] Ultrasonic elastography can objectively evaluate the relative elastic hardness of breast tumors, and identify whether the breast lumps are benign or malignant with high diagnostic value.
