摘　　要：目的 :探讨新型钼靶X线机与彩色多普勒超声 (colorDopplerultrasonography,CDUS)检查对乳腺结节的诊断价值。方法 :对直径≤ 2 .0cm的 118例钼靶X线、CDUS乳腺结节资料采用双盲法进行前瞻性分析、定性诊断 ,并与术后病理结果对照。结果 :钼靶X线与CDUS对乳腺结节灶性质的判断、灵敏度分别为 96 .2 %、85 .9%;特异性分别为 10 0 .0 %、92 .5 %;总一致性比较 ,钼靶X线 (97.5 %)优于CDUS(88.1%) (P <0 .0 1) ;二者联合诊断与单独钼靶X线诊断结果相比较 ,灵敏度、特异度、总一致性均无显著性差异 (P >0 .0 5 ) ;彩色多普勒血流显像 (colorDopplerflowimaging ,CDFI)检测良、恶性乳腺结节灶血流信号率有显著性差异 (P <0 .0 0 1) ,血流丰富率亦有显著性差异 (P <0 .0 0 1) ;检测到的良、恶性结节灶内血流阻力指数 (resistanceindex ,RI)及血流搏动指数 (pulsatilityindex ,PI)均无显著性差异。结论 :新型钼靶X线机与CDUS均为评价乳腺结节灶较理想的设备。二者相比较 ,钼靶X线优于CDUS ,但两者在诊断乳腺结节性质方面有很强的互补 ;CDFI检测乳腺结节灶内血流敏感性高 。Objective:[WT5”BZ]To evaluate the diagnostic value of mammography by new type molybdenum x ray machine and color Doppler ultrasonography(CDUS)for breast nodule.ethods:118 breast nodules(≤2.0cm)were examined with both new type x ray machine and CDUS.Diagnosis was made in every case with double blind method and compared with the pathological results.Results:The sensitivity of molybdenum mammography and CDUS is 96.2% and 85.9% respectively,the specificity is 100.0%、92.5% respectively;Comparing the diagnostic crude consistency (97.5% vs 88.1%)of mammography with that of CDUS,mammography is better than CDUS([WT5”BX]P[WT5”BZ]<0.01);Comparing mammography only with mammography and CDUS combined,there is no significant difference in sensitivity、specificity and crude consistency([WT5”BX]P[WT5”BZ]>0.05);Using CDFI,there is significant difference in blood flow signal([WT5”BX]P[WT5”BZ]=0.001)and the ratio of rich blood flow([WT5”BX]P[WT5”BZ]<0.001)between benign and malignant nodules.There is no significant difference in mean resistance index(RI)and mean pulsatility index(PI)between benign and malignant nodules.[WT5”HZ]Conclusion:[WT5”BZ]Both molybdenum x ray machine mammography and CDUS are ideal techniques for evaluation of breast nodules.The mammography is better than CDUS,but combining mammography and CDUS can compensate each other.CDFI has high sensitivity in detecting blood flow of breast nodule,it can be an auxiliary method of B type US in distinguishing the nature of breast nodes.
