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。
Objective To investigate the clinical value of MRI and mammography in the diagnosis of breast cancer. Methods 75 cases of elderly patients with breast cancer were selected, all underwent mammography, MRI and pathological examination. The results of different tests for statistics and comparison. Results The coincidence rate of digital mammography was the lowest. The coincidence rates of plain MRI, enhanced MRI and mammography combined with MRI increased successively. The difference between the two methods was statistically significant (P <0.05). There was no significant difference between the two imaging examinations (P> 0.05). The rate of mammography in calcification was significantly higher than that in MRI (P <0.05). The tumor or nodules, pectoralis major invasion and axillary lymph node enlargement MRI showed significantly higher than the molybdenum target (P <0.05). Conclusion The diagnosis of breast cancer, mammography and MRI examination have their own advantages and disadvantages, the combination of the two tests although the detection rate can be increased, but the cost is relatively high, clinical work should be flexible according to the situation.
