摘　　要：目的分析超微血管成像(SMI技术)对乳腺癌化疗患者的治疗效果的评估作用。方法研究对象为本院2019年1月至2020年1月收治的60例乳腺癌患者,所有患者均接受化疗治疗。在化疗前后利用SMI技术对患者进行检查,观察患者血流动力学参数、血流分级、肿瘤最大径线变化情况。结果SMI检查结果显示,化疗后患者的最大径线、血管收缩期最大流速(Vmax)、阻力指数(RI)均低于化疗前,差异均具有统计学意义(P<0.05);化疗后血流分级Ⅱ级、Ⅲ级人数明显减少,0级、Ⅰ级人数明显增多,与化疗前比较差异有统计学意义(P<0.05)。结论SMI技术简单快捷、价格低廉,可清楚显示乳腺癌患者血流动力学改变情况,通过对化疗前后微血管变化情况对比准确评估化疗效果。Objective To analyze the evaluation effect of ultravascular imaging(SMI)on the therapeutic effect of breast cancer chemotherapy patients.Methods The research subjects were 60 breast cancer patients admitted to our hospital from January 2019 to January 2020,and all patients received chemotherapy.Before and after chemotherapy,the patient was examined using SMI technology to observe the changes in hemodynamic parameters,blood flow grade,and maximum tumor diameter.Results The results of SMI examination showed that the maximum diameter,maximum flow rate of vasoconstriction(Vmax)and resistance index(RI)of patients after chemotherapy were lower than before chemotherapy,and the differences were statistically significant(P<0.05);blood flow after chemotherapy.The number of people in gradesⅡandⅢdecreased significantly,and the number of people in grade 0 andⅠincreased significantly,which was significantly different from that before chemotherapy(P<0.05).Conclusion The SMI technique is simple,fast,and inexpensive,and can clearly show the hemodynamic changes in breast cancer patients.The effect of chemotherapy can be accurately assessed by comparing the changes of microvessels before and after chemotherapy.
