摘　　要：目的:探讨超声弹性成像(UE)与彩色多普勒超声在乳腺良恶性占位病变诊断中的价值。方法:选择乳腺占位性病变的女性患者195例,共234个病灶,所有病灶均行彩色多普勒超声检查及UE检查,并以病理检查为金标准,比较彩色多普勒超声检查及UE对病灶良、恶性诊断的敏感性、特异性及准确性。结果:共有234个乳腺占位性病灶,病理诊断为良性病灶146个,恶性病灶88个。UE、CDFI血流分级、RI、CDFI血流分级联合RI对恶性占位性病灶诊断敏感性、特异性性、准确性分别为(87.5%、95.2%、92.3%)、(69.3%、71.9%、75.2%)、(76.5%、62.2%、68.7%)、(55.7%、84.9%、73.9%);UE诊断正确病灶数为216个,误诊病灶18个,而CDFI血流分级联合RI正确诊断病灶数为173个,误诊病灶61个,UE诊断乳腺良恶性病灶准确性高于彩色多普勒超声(P<0.05)。结论:UE对乳腺占位性病变的良恶性诊断的敏感性、特异性、准确性高于多普勒超声,但也存在一定的误诊率。因此,联合其他影像学检查可进一步提高UE对乳腺占位性病灶良恶性的诊断准确率。Objective： To investigate the diagnosis values about ultrasound elasticity imaging（ UE） and color Doppler ultrasound applicating in breast benign or malignant lesions. Methods： 195 female patients had 234 breast space occupied lesions, all lesions were examined with color Doppler ultrasound and UE examination, and pathological examination was gold standard,the thesensitivity,specificity and accuracy of diagnosising benign or malignant lesions by color Doppler ultrasonography and UE were compared. Results： Among 234 breast lesions,there were 146 benign lesions and 88 malignant lesions by pathologic diagnosis. The diagnosis sensitivity,specificity,accuracy of malignant occupied lesions by UE,CDFI flow grade,RI,CDFI flow grade combinated with RI were respectively（ 87. 5%,95. 2%,92. 3%）,（ 69. 3%,71. 9%,75. 2%）,（ 76. 5%,62. 2%,68. 7%）,（ 55. 7%,84. 9%,73. 9%）; There were 216 lesions correctly diagnosised by UE,18 lesions were misdiagnosised.There were 173 lesions which were correctly diagnosised by CDFI flow grade combinated with RI diagnosis,61 lesions were misdiagnosised,the diagnosis accuracy by UE in benign and malignant breast lesions was higher than that by color Doppler ultrasonography（ P 〈0. 05）. Conclusion： The diagnosis accuracy,sensitivity,specificity by UE in benign and malignant breast lesions are higher than those by Doppler ultrasound,but also it has some misdiagnosis rate. Therefore,combining with other imaging can improve UE＇s diagnosis accuracy rate in benign or malignant breast space occupied lesion.
