目的:分析乳腺恶性肿瘤的声像特征,提高超声对乳腺恶性肿瘤诊断价值。方法:回顾性分析53例经病理证实的乳腺恶性肿瘤在二维超声、彩色多普勒、组织弹性成像、声学造影及淋巴结转移的规律。结果:53例乳腺恶性肿瘤二维超声显示毛刺征32例,周边有高回声27例,后方有衰减的37例,针尖钙化的3例;多普勒和彩色能量图中显示未见明显血流信号的1例,可见少量血流信号52例,穿入型血流的31例,分支状血流的29例,不规则血流血流信号的19例;组织弹性成像的技术中,弹性分数越高灵敏度逐渐增高,特异系性逐渐减低,准确性逐渐减低;超声造影技术中恶性肿瘤达峰值较快,血管数量较多;恶性肿瘤淋巴结晚期转移的骨髓破坏、淋巴门消失。结论:乳腺恶性肿瘤在声像图上特征性表现,超声检查方法方便、安全、无痛,有较高的敏感性,对组织显示十分清晰,而在乳腺疾病的诊断中有着不可替代的优势,故能对乳腺良恶性肿瘤鉴别诊断分析为临床提高可靠的诊断指标,对治疗提供重要的参考价值,提高生命质量。
Objective: To analyze the sonographic features of breast malignant tumors and to improve the diagnostic value of ultrasound in malignant breast tumors. Methods: A retrospective analysis of 53 cases of pathologically confirmed breast cancer in two-dimensional ultrasound, color Doppler, tissue elastography, acoustic contrast and lymph node metastasis rule. Results: Fifty-three cases of malignant breast tumors showed 32 cases of burr by two-dimensional ultrasonography, 27 cases had hyperechoic circumferences, 37 cases attenuated behind and 3 cases of acupoint calcification. Doppler and color energy showed no significant blood flow Signal in 1 case, showing a small amount of blood flow signal in 52 cases, penetrating blood flow in 31 cases, 29 cases of branch-shaped blood flow, irregular blood flow signal in 19 cases; tissue elastography, the elastic fraction The higher the sensitivity gradually increased, the specificity of the system gradually reduced, the accuracy gradually reduced; ultrasound imaging of malignant tumors peaked faster, more blood vessels; lymph node metastasis of malignant tumor bone marrow destruction, lymphatic door disappeared. Conclusion: Malignant breast tumor is characterized by sonographic features. The sonographic method is convenient, safe, painless and sensitive. It shows the tissue clearly, but has an irreplaceable advantage in the diagnosis of breast disease. Therefore, the differential diagnosis of benign and malignant breast tumors as a clinical diagnostic index to improve the reliability of the treatment provides an important reference value and improve the quality of life.
