【摘要】：目的:探讨超微血管成像技术在乳腺癌新辅助化疗(Neoadjuvant chemotherapy,NAC)疗效评估中的应用价值。方法:对57例乳腺癌患者73个肿瘤行NAC前后采用超微血管成像技术(Superb microvascular imaging,SMI)检查,对肿瘤最大径线、血流分级及血流动力学参数进行分析。结果:73个肿瘤NAC后最大径线较NAC前缩小;行彩色模式SMI检查显示化疗后血流分级(以0级、Ⅰ级为主)较化疗前(以Ⅱ级、Ⅲ级为主)下降,肿瘤内血流动力学参数Vmax、RI均降低(P0.05)。超声评价本组中完全缓解21例,部分缓解37例,总有效率79.5%,与病理评价结果一致性较好。结论:SMI为临床评估乳腺癌NAC疗效提供了一种无创、快捷、有效的检查方法。
[Abstract]:Objective: to evaluate the value of supermicrovascular imaging in evaluating the efficacy of neoadjuvant chemotherapy in breast cancer. Methods: supermicrovascular imaging was performed before and after NAC in 57 patients with breast cancer. The maximum diameter, blood flow grade and hemodynamic parameters of the tumor were analyzed. Results: the maximum diameter of 73 tumors after NAC was smaller than that before NAC, and the color mode SMI examination showed the blood flow grade after chemotherapy (grade 0). Compared with those before chemotherapy (grade 鈪，
