彩色多普勒超声结合超声弹性成像对非哺乳期乳腺炎、乳腺癌的诊断分析

Diagnosis of non lactation mastitis,breast cancer by color doppler flow imaging and ultrasonic elastography

目的：运用彩色多普勒超声技术（CDFI）结合超声弹性成像技术（UE）观察分析非哺乳期乳腺炎、乳腺癌的超声参数特征，并探讨其临床应用价值。方法回顾性分析因触及乳腺肿物而进行治疗的85例女性患者的临床资料，共85个乳腺病灶。所有患者均获得病理证实，并根据病理结果，分为非哺乳期乳腺炎组（NLM组）共计28例，乳腺癌组（Ca组）共计57例。患者均在治疗前接受CDFI检查以及UE检查，对两组患者所获得的超声参数进行比较分析。结果 NLM组乳腺病灶血流分级中0～I级所占比例（71．43％）和阻力指数（RI）＜0．7所占比例（82．14％）明显高于Ca组（24．56％、15．79％），而Ⅱ～Ⅲ级所占比例（28．57％）和RI≥0．7所占比例（17．86％）明显低于 Ca组（75．44％、84．21％），差异均有统计学意义（χ2＝17．185、35.217，均P＜0．05）；NLM组乳腺病灶UE评分[（1．75±0．97）分]以及应变率比值（1．64±0．83）明显低于Ca组[（4．19±0．74）分，（5．03±1．08）]，差异均有统计学意义（t＝-12．873、-14．623，均P＜0．05）；CDFI联合UE的准确率（89．41％）高于UE 的准确率（76．47％）、CDFI 的准确率（67．06％），差异有统计学意义（χ2＝12.337，P＜0．05）。结论 CDFI、UE对非哺乳期乳腺炎以及乳腺癌均具有一定的诊断能力，两者联合可获得更高的诊断准确率，值得临床上推广应用。

Objective To study ultrasonic parameters characteristics of lactation mastitis,breast cancer by using color doppler flow imaging（CDFI）and ultrasonic elastography（UE）,and to explore its clinical value.Methods Retrospective analysis was conducted in the clinical data of 85 female patients （a total of 85 breast lesions）.All patients were confirmed by pathology,and according to the results of pathology,they were divided into non lactation mastitis group（group NLM,a total of 28 cases）,breast cancer group（group Ca,a total of 57 cases）.All patients accepted CDFI and UE before treatment,and compared ultrasound parameters between the two groups.Results The＆amp;nbsp;proportions of class 0~I（71.43%）and RI〈0.7（82.14%）in group NLM were significantly higher than those in group Ca,while the proportions of classⅡ ~Ⅲ（28.57%）and RI≥0.7 （17.86%）were significantly lower than 75.44%,84.21% in group Ca（χ2 =17.185,35.217,all P〈0.05）.The UE ratings（1.75 ±0.97）and the strain rate ratio （1.64 ±0.83）in NLMgroup were lower than （4.19 ±0.74）,（5.03 ±1.08）in group Ca（t=-12.873,-14.623,all P〈0.05）.The accuracy of CDFI ＋UE（89.41%）was higher than the accuracy of UE（76.47%）or the accuracy of CDFI（67.06%）（χ2 =12.337,P〈0.05）.Conclusion CDFI,UE have a certain diagnosis ability for non lactation mastitis and breast cancer,combining both can obtain better diagnostic value,which is worthy of clinical application.
