彩色多普勒血流成像联合弹性成像多参数分析在乳腺肿块鉴别诊断中的价值(1)
摘要:目的 探讨常规多普勒超声(CDFI)联合超声弹性成像(UE)多参数分析在乳腺良惡性肿块鉴别诊断中的价值。方法 回顾性分析2015年1月~12月85例患者的92个乳腺肿块的CDFI表现及UE多参数分析,以术后病理结果作为金标准,对CDFI、UE及两者联合诊断对乳腺肿块的鉴别价值采用SPSS18.0 统计软件进行分析,率的比较采用χ2检验,P<0.05 为差异有统计学意义。结果 CDFI结果与病理结果相符67个病灶,其诊断敏感性、特异性、准确率分别为:70.0%(16/23),73.9%(51/69),71.7%(67/92)。UE多参数综合诊断结果与病理结果相符71个病灶,其诊断敏感性、特异性及准确性分别为73.9%(17/23),78.4%(54/69),77.2%(71/92)。CDFI与UE联合诊断敏感性、特异性、准确率分别为:86.9%(20/23),89.9%(62/69),89.1%(82/92)。以上三种诊断方法对乳腺肿块的诊断准确率比较,联合应用常规超声与弹性成像技术能明显提高诊断敏感性,特异性及准确率(P<0.05)。结论 CDFI联合UE多参数分析可提高乳腺肿块诊断准确率。

Abstract:Objective To study the value of the combination of color doppler ultrasound and elastography multiparameter in the diagnosis of breast tumor. Methods Clinical characteristics of 92 nodules in 85 patients were examined by color doppler ultrasound and elastography, with postoperative pathology results as "gold standard". Comparison was made between the diagnosis of the ultrasound and pathology results by using SPASS 18.0 software to evaluate clinical value of combined application of doppler ultrasound and elastography in the differential diagnosis of breast nodules. The test was used in the ratio comparison, and P<0.05 was considered statistically significant. Results The diagnostic results of 67 nodules using CDFI were in accordance with the athological results. The sensitivity, specificity,and accuracy of CDFI in detecting breast nodules were 70.0%,73.9%,and 71.7% respectively. 71 nodules using UE were in accordance with the athological results. The sensitivity, specificity,and accuracy of CDFI in detecting breast nodules were 73.9%,78.4%,and 77.2% respectively. Those of combination of CDFI and UE were 86.9%,89.9%,and 89.1% respectively. There wsa significant difference between three diagnostic performances in the differential diagnosis of benign and malignant breast nodules(P<0.05). Conclusion The combination of CDFI and UE could improve the diagnostic accuracy of breast nodules.

乳腺癌发病率位于女性恶性肿瘤的首位,严重威胁女性的身心健康。早期诊断乳腺癌可以对临床治疗方案的选择起到关键的作用,对乳腺癌预后极为重要。高频彩超因无创价廉便捷成为乳腺检查的首选方法,彩色多普勒超声血流显像(color doppler flow imaging,CDFI)从血供方面为乳腺良、恶性病灶鉴别诊断提供帮助,但有时鉴别诊断比较困难[1]。超声弹性成像(ultrasonic elastography, UE)是从病灶质地反映病灶性质的一种新技术[2]。本研究旨在探讨UE多参数分析(弹性成像评分、面积比值、应变率比值)联合CDFI在提高乳腺癌诊断准确率中的价值。
1资料与方法
1.1一般资料 回顾性分析2015年1月~12月我院术后病理证实,同时接受UE和CDFI联合诊断的85例乳腺肿块患者,92个病灶。其中良性病灶69个,恶性病灶23个。患者均为女性,年龄在24~77岁,平均年龄59岁。

1.2仪器与方法 超声仪器采用LOGIC E9和Esaote MyLab twice彩色多普勒超声诊断仪,探头频率4~13 MHz。充分暴露乳腺和腋窝后常规超声检查,记录病灶位置、大小、形态、内部回声、有无钙化等,重点观察病灶内部及周边血流信号及频谱等,采用Adler 半定量法[3]对病灶的血流分级。0级:病灶内未检测出血流信号;Ⅰ级;为少量血流,可见1~2 处点状或细棒状血管,管径<1 mm;Ⅱ级:为中量血流,可见一条主要血管,其长度超过病灶半径或同时可见2~3 条小血管;Ⅲ级:为多量血流,可见4条以上的血管,或血管相连通交织成网状。0~Ⅰ级:判定为良性病灶;Ⅱ~Ⅲ级:判定为恶性病灶。然后切换入超声弹性成像模式, 取样框约病灶范围2倍,包括病灶组织及周围组织的皮下脂肪组织及部分胸肌组织, 手持探头在病灶部位作微小振动,获取弹性图像。采用由Itoh 等[2]提出的弹性成像评分5分法,对乳腺实性病灶进行评分,1~3 分为良性病灶,4~5 分为恶性病灶。在弹性图上计算病灶的应变率和同深度正常乳腺组织的应变率比值,本研究中以3.0为界值,比值≥3.0为恶性,<3.0为良性。在双模图上勾画弹性图与二维图肿块面积,计算面积比,比值≥1.1为恶性,<1.1为良性。为减少主观性,CDFI、UE 均由同一名经验丰富的副主任医师完成。, 百拇医药(张文 孙红光 戚庭月)
