目的 探讨钼靶X线联合动态增强 MRI对乳腺疾病的诊断价值研究。方法 选 取我院2015年6月-2016年2月经病理检查 诊治的乳腺肿块患者62例，患者均进行钼 靶X线检查、MRI平扫、MRI动态增强及弥 散加权成像扫描检查，观察乳腺疾病分别 在钼靶X线、MRI检查中的影像学表现及 诊断准确率，分析钼靶X线检查联合动态 增强MRI检查对乳腺疾病的诊断价值。结 果 钼靶X线检查准确诊断乳腺疾病患者43 例，其诊断准确率为69.35%(43/62)；MRI 检查准确诊断乳腺疾病患者57例，其诊 断准确率为91.93%(57/62)；联合检查诊 断准确率为96.77%(60/62)，高于单纯钼 靶X线及动态增强MRI检查的准确率，两组 数据差异具有统计学意义(P<0.05)。结论 动态增强MRI对乳腺疾病诊断的准确度高 于钼靶X线检查，钼靶X线检查联合动态增 强MRI检查能提高对乳腺疾病诊断的准确 率，为临床及时制定合理治疗方案提供相 关影像学资料。

Objective To investigate the diagnostic value of mammography combined with dynamic contrast-enhanced MRI in breast diseases. Methods 62 cases of breast masses diagnosed by pathological examination were selected as subjects admitted to our hospital from June, 2015 to February, 2016. The patients were examined by mammography, MRI, MR enhancement and diffusion-weighted imaging. The imaging findings and diagnostic accuracy of molybdenum target X-ray and MRI were analyzed respectively. The diagnostic value of mammography combined with dynamic contrast-enhanced MRI was analyzed. Results The diagnostic accuracy of mammography was 43.35% (43/62). MRI diagnosis was performed in 57 patients with breast disease. The diagnostic accuracy was 91.93% (57/62) (P<0.05). The accuracy of the combined examination was 96.77% (60/62), which was higher than that of pure mammography and dynamic contrastenhanced MRI. The difference was statistically significant (P<0.05). Conclusion Dynamic contrast-enhanced MRI is more accurate than mammography, and mammography combined with dynamic contrast-enhanced MRI can improve the accuracy of breast disease diagnosis, which provides relevant imaging information for the clinical development of reasonable treatment plan.
