目的探讨CT和MRI应用于乳腺 肿瘤诊断的临床价值及其特征表现。方 法 以我院放射科收治的58例经病理证实 的乳腺肿瘤患者为研究对象，根据其临床 资料进行回顾性分析和总结，分别对其进 行CT和MRI检查，对比分析两种检查方式 的诊断结果。结果 MRI检出乳腺良性肿瘤 29例，乳腺癌23，CT检出乳腺良性肿瘤19 例，乳腺癌11例，MRI对乳腺肿瘤的检出 率明显高于CT，p＜0.05,差异显著。结论 CT和MRI在诊断乳腺肿瘤方面均具有较高 的临床价值，其影像具有一定的特征性， 但是MRI可以提供更多的信息，可以为患 者的后续治疗提供重要的参考依据，具有 较高的临床应用推广价值。

Objective This Paper is to study clinical value of CT and MRI applied to diagnose the breast tumor and its characteristics. Methods Fifty eight patients who were confirmed to suffer from breast cancer, by pathology admitted by the Radiology Department of the Hospital were selected as research objects, who were retrospectively analyzed and summarized according to the clinical data, patients were subject to CT and MRI examinations respectively, and two types of inspection diagnosis were contrasted and analyzed. Results MRI detected 29 patients suffering from benign breast tumor and 23 patients with breast cancer, CT detected 19 patients with benign breast tumor and 11 patients with breast cancer, the detection rate of MRI on the breast tumor was obviously higher than that of CT(p<0.05), and the difference was significant. Conclusions Both CT and MRI deliver high clinical value in diagnosis of breast tumor, their images pose certain characteristic, but MRI is capable of providing more information, and it can provide important reference basis for subsequent treatment, throwing high value of clinical application and promotion.
