MRI与乳腺钼靶应用于乳腺癌诊断的临床对照研究

目的探讨MRI与乳腺钼靶对乳腺癌诊断的临床应用价值。方法选取老年乳腺癌患者75例，均行钼靶、MRI、病理学检查。对其不同检查结果进行统计和比较。结果数字钼靶诊断符合率最低，平扫MRI、增强MRI以及钼靶联合MRI诊断符合率依次升高，不同影像学检查方法之间比较差异明显，有统计学意义（P〈0．05）。毛刺或星芒征两种影像学检查显现差别不大（P〉0.05）；钙化灶钼靶显示率明显高于MRI（P〈0．05）；肿块或结节、胸大肌侵犯以及腋窝淋巴结肿大MRI显示率均明显高于钼靶（P〈0．05）。结论对乳腺癌进行诊断时，钼靶检查与MRI检查各有优缺点，两种检查联合应用虽然可以提高检出率，但费用也相对较高，临床工作中应根据情况灵活掌握。

The clinical contrast research for MRI and mammography applied in the diagnosis of breast cancer

Objective To investigate the clinical value of the application for MRI and mammograpby in the diagnosis of breast cancer. Methods 75 cases of elderly patients with breast cancer were chosen. All patients were taken with mammography, MRI, pathological examination. The different inspection results were taken for statistics and comparison. Results The diagnosis of digital mammography was with the lowest rate, unenhaneed MRI, enhanced MRI and mammography combined MRI diagnosis rate increased successively, there were obvious difference between the different imaging studies, and there was statistical significance（P〈0.05）. The burr or astral levy two imaging studies showed little difference（P〉0.05）. The calcification mammography display was significantly higher than MRI（P〈0.05）. The lumps or nodules, pectoralis major violation of axillary lymph nodes MRI showed significantly higher than that of mammography（P〈0.05）. Conclusion The diagnosis of breast cancer, mammography and MRI has advantages and disadvantages, two checks in combination can improve the detection rate, but the costs are relatively high. The clinical work should master flexibly depending on the circumstances.
