目的:探讨核磁共振(MRI)、钼靶X射线摄影和彩色多普勒超声(CDUS)单独或联合使用对未触及肿块乳腺癌早期诊断的实用价值。方法:150例未触及肿块的可疑乳腺疾病患者均行MRI、钼靶X射线摄影和CDUS检查,对其单独或并联检查的结果进行分析,并与病理结果进行对照。结果:MRI、钼靶X射线摄影、CUDS单独或联合使用与病理结果呈正关联,以上3种方法单独应用的诊断效能两两比较差异无统计学意义(P>0.05),MRI并联钼靶摄影、MRI并联CDUS、钼靶摄影并联CDUS以及3种方法并联应用的诊断效能比较,差异均无统计学意义(P>0.05),但上述4种并联应用方法的诊断效能均高于单独应用的诊断效能。相对而言,钼靶X射线摄影与CUDS并联检查可明显提高未触及肿块的乳腺癌的检出阳性率和灵敏度,诊断效能最好。结论:MRI、CDUS、钼靶X射线摄影单独或联合使用均可应用于未触及肿块的乳腺癌早期诊断,结合我国的实际情况,钼靶X射线摄影与CUDS联合应用可作为未触及肿块的乳腺癌的首选筛查方法。但MRI也有一定的临床应用价值。
Objective: To investigate the practical value of MRI, mammography and color doppler ultrasound (CDUS) alone or in combination on the early diagnosis of untreated breast cancer. Methods: 150 cases of suspected breast disease without palpable mass were performed MRI, mammography and CDUS examinations. The results of single or parallel examinations were analyzed and compared with the pathological findings. Results: MRI, mammography and CUDS alone or in combination were positively correlated with the pathological results. There was no significant difference in the diagnostic efficacy of these three methods alone (P> 0.05), MRI parallel mammography, MRI parallel CDUS, mammography parallel CDUS and the three methods in parallel, the difference was not statistically significant (P> 0.05), but the diagnostic efficacy of the above four parallel methods were higher than the diagnostic efficacy alone . In contrast, molybdenum target X-ray photography and CUDS parallel examination can significantly improve the positive rate and sensitivity of breast cancer without palpable mass, the diagnosis of the best. Conclusion: MRI, CDUS and mammography alone or in combination can be applied to the early diagnosis of breast cancer without palpable mass. Combined with the actual situation in our country, mammography combined with CUDS can be used as the breast without palpable mass Cancer screening method of choice. But MRI also has some clinical value.
