摘要
目的探讨彩色多普勒(CDFI)及超声能量图(PDI)在乳腺癌新辅助化疗前后诊断中的价值。方法采用彩色多普勒及超声能量图对120例乳腺癌患者新辅助化疗前后原发灶及淋巴结的大小,二维超声图像,血流分布,血流动力学参数等各项指标的变化进行观测分析。结果 120例患者原发灶化疗前平均体积为(17.66±9.87)cm3,化疗后为(8.66±5.68)cm3;平均Vmax及RI在化疗前后分别为(33.34±13.63)cm/s、(0.84±0.11)和(20.12±8.27)cm/s、(0.68±0.08),化疗前后差异均有统计学意义,P<0.05。结论彩色多普勒及超声能量图可为乳腺癌新辅助化疗提供简便、安全的疗效观察手段。
Objective To evaluate the value of color doppler（CDFI） and ultrasonic energy diagram（PDI） for breast cancer diagnosis before and after neoadjuvant chemotherapy.Methods The primary tumors and node metastases of 120 patients with breast cancer were evaluated by color Doppler and ultrasonic energy before and after chemotherapy.The size of the tumors,two-dimensional ultrasound images,blood flow distribution,and other hemodynamic parameters were analyzed.Results The mean volume of the tumors was（17.66±9.87）cm3 and（8.66±5.68）cm3 before and after chemotherapy.The mean Vmax and RI before and after chemotherapy were（33.34±13.63）cm/s,（0.84± 0.11）and（20.12 ± 8.27）cm/s,and（0.68±0.08）,respectively,which was significantly different（P0.05）.Conclusion Color Doppler and ultrasound energy plan is a simple,effective and safe measures of neoadjuvant chemotherapy for breast cancer.
