超声血流能量图与弹性成像在乳腺肿块良恶性鉴别诊断中的价值比较

Comparison of PDI and elastograph in differential diagnosing beast cancer and beast benign tumor

目的探讨高频彩色多普勒超声血流能量图PDI与弹性成像在乳腺肿块良恶性鉴别诊断中的价值。方法选取经病理结果证实的92个乳腺肿块,应用高频彩色多普勒超声PDI观察血流特点,同时进行超声弹性成像检查,并与术后病理结果对照,对二者鉴别乳腺肿块的效果分别进行评估。结果 PDI诊断乳腺癌的灵敏性、特异性和符合率分别为66.7%、71.4%、69.6%,超声弹性成像诊断乳腺癌的灵敏性、特异性和符合率分别为80.6%、85.7%、83.7%,两种方法符合率比较,χ2=5.129,P<0.05,有统计学意义。结论弹性成像在乳腺癌的鉴别诊断中准确度高于PDI。

Objective To explore the value of PDI(Power Doppler Imaging)and elastograph in differential diagnosis between beast cancer and beast benign tumor by the detection of high frequency color Doppler ultrasound.Methods Selecting 92 beast tumors evidenced by the pathological results,observing blood characteristics of high frequency color Doppler ultrasonic PDI and elastograph,and compared with the postoperative pathological results,the differential diagnostic effects of blood characteristics and Elastograph have been estimated.Results The sensitivity,specificity and accuracy of PDI in diagnosis of beast cancer were 66.7%.71.4%.69.6%.the sensitivity,specificity and accuracy of ultrasonic elastography in diagnosis of breast cancer were 80.6%,85.7%,83.7%,comparison of accuracy between the two methods,x2=5.129,P<0.05,means ststistic significance can be found.Conclusion The accuracy of Elastograph is higer than PDI in differentially diagnosing beast cancer.
