摘　　要：目的探讨钼靶、超声联合MRI检查在早期乳腺癌患者临床诊断中的应用价值。方法收集经手术和病理证实的46例乳腺癌病例作为研究对象,均行X线钼靶、彩色多普勒超声、MRI检查,观察三种检查方法的影像学表现,并比较不同检查方法对肿块、钙化、肿块内部结构、微小病灶等方面的敏感性,比较诊断符合率。结果三种检查方法对肿块、微小病灶敏感性的两两差异无统计学意义(P>0.05);X线钼靶与彩超对钙化敏感性均高于MRI,彩超与MRI对肿块内部结构的敏感性均高于X线钼靶,差异有统计学意义(P<0.05)。X线钼靶、彩超、MRI的诊断符合率分别为89.1%、82.6%、78.3%,联合诊断符合率为97.8%。结论钼靶X线、彩色多普勒超声、MRI检查方法对早期乳腺癌的显示各有其优势与不足,诊断准确性有限,而采取三者的联合检查可最大限度地避免漏误诊,提高诊断准确率。Objective To explore the mammography, ultrasonography and MRI examination in the clinical application value of early diagnosis of breast cancer patients. Methods 46 cases with breast cancer confirmed by surgery and pathology as the research object, underwent X-ray mammography, color Doppler ultrasound, MRI examination, to observe the performance of three methods of imaging, and check method to compare different mass, calcification, the internal structure of mass sensitivity of small lesions, compared the diagnostic rate. Results of three methods of the masses, no statistically significant differences in the sensitivity of two two small lesions（P〈0.05）; mammography and ultrasonography were higher than MRI on calcification of sensitivity, color Doppler ultrasound and MRI were higher than that of X-ray mammography is sensitive to the internal structure of the masses, the difference was statistically significant（P〈0.05）. X-ray mammography, ultrasound and MRI diagnosis coincidence rate was 89.1%,82.6%,78.3%, the combined diagnosis with rate was 97.8%. Conclusions Conclusions mammography, color Doppler ultrasound, MRI examination method for early breast cancer showed that each has its advantages and disadvantages, diagnostic accuracy is limited, and take the joint inspection can maximize to avoid misdiagnosis and improve the diagnostic accuracy.
