不同影像学方法诊断乳腺癌的差异分析

Difference Analysis of Different Imaging Methods in the Diagnosis of Breast Cancer

本文运用声触诊组织定量(VTQ)技术测量剪切波速度(SWV),并对比SWV、X线、普通彩超在乳腺癌诊断中的价值。选取85例存在乳腺肿块的乳腺病变患者为研究对象,所有患者均接受X线、普通彩超、VTQ检查及手术病理活检,以病理结果为金标准将乳腺癌患者设置为乳腺癌组(52例),将良性肿块患者设置为良性组(33例),对比两组患者的血流阻力指数(RI)、SWV数值、血流显示率,分析不同影像学方式诊断乳腺癌的效能。乳腺癌组患者的RI、SWV、血流显示率数值大于良性组(P<0.05);影像学诊断结果显示,X线诊断乳腺癌的灵敏度为32.69%、特异度为45.45%,普通彩超诊断乳腺癌的灵敏度为69.23%、特异度为69.70%,SWV诊断乳腺癌的灵敏度为82.69%、特异度为75.76%;SWV、普通彩超、X线诊断乳腺癌的AUC分别为0.801、0.687、0.453。相比X线、普通彩超等影像学方式,SWV诊断乳腺癌的效能最高,SWV数值可对病灶硬度进行评估,弥补了普通超声的不足。

Measured the shear wave velocity(SWV)in this paper by virtual touch tissue quantification(VTQ),and then compared the value of SWV,X-ray and color Doppler ultrasound in the diagnosis of breast cancer.85patients with breast lesions with breast masses were selected as the research objects.All patients received X-ray,ordinary color Doppler ultrasound,VTQ and surgical pathological biopsy.Taking the pathological results as the gold standard,and the patients with breast cancer were set as the breast cancer group(52cases),and the patients with benign breast masses were set as the benign group(33cases).Compared the blood flow resistance index(RI),SWV value and blood flow display rate of the two groups,and analyzed the efficacy of different imaging methods in the diagnosis of breast cancer.The RI,SWV and blood flow display rates in the breast cancer group were higher than those in the benign group(P<0.05).The imaging diagnosis results showed that the sensitivity and specificity of X-ray in the diagnosis of breast cancer were 32.69%and 45.45%,respectively.The sensitivity and specificity of ordinary color Doppler ultrasound in the diagnosis of breast cancer were 69.23%and 69.70%,respectively.The sensitivity and specificity of SWV in the diagnosis of breast cancer were 82.69%and 75.76%,respectively.The AUC of breast cancer diagnosed by SWV,conventional color ultrasound and X-ray were 0.801,0.687and 0.453,respectively.Compared with X-ray,common color ultrasound and other imaging methods,the SWV has the highest efficiency in diagnosing breast cancer,and SWV value can evaluate the hardness of lesions,making up for the deficiency of common ultrasound.
