目的:探讨核磁共振成像(MRI)与计算机X线断层扫描(CT)对乳腺癌患者的临床诊断价值。方法:选取2012年10月~2013年10月经MRI或CT检查后拟诊为乳腺癌的98例患者为研究对象,均经病理穿刺或手术确诊,比较两种检查方法对鉴别良恶性乳腺肿瘤、不同类型乳腺癌及病灶大小的临床价值。结果:MRI、CT对乳腺癌的检出率为94.44%、96.67%,灵敏度为98.82%、96.67%,特异度为53.84%、54.54%,差异无统计学意义(P>0.05)。CT对导管内原位癌(DCIS)检测率高于MRI,差异有统计学意义(P<0.05)。CT、MR对浸润性小叶癌(LDC)及浸润性导管癌(IDC)检测率无统计学差异(P>0.05)。结论:MRI与CT对鉴别乳腺癌良恶性肿瘤均具有一定的诊断价值,CT对乳腺癌分类检测率较高。临床可根据患者实际情况选择合适的诊查方法,以提高乳腺癌检出率。
Objective: To investigate the clinical value of MRI and computed tomography (CT) in the diagnosis of breast cancer. Methods: A total of 98 patients diagnosed as breast cancer after MRI or CT examination from October 2012 to October 2013 were selected as the study objects. All the patients were diagnosed by pathological puncture or operation. The two methods were compared to distinguish benign and malignant breast tumors, Different types of breast cancer and the clinical value of lesion size. Results: The detection rates of breast cancer by MRI and CT were 94.44% and 96.67%, respectively. The sensitivity was 98.82% and 96.67% respectively. The specificity was 53.84% and 54.54% respectively. There was no significant difference between them (P> 0.05). CT detection of ductal carcinoma in situ (DCIS) was higher than MRI, the difference was statistically significant (P <0.05). There was no significant difference in the detection rates of CT and MR between invasive lobular carcinoma (IDC) and invasive ductal carcinoma (IDC) (P> 0.05). Conclusion: Both MRI and CT have certain diagnostic value in the differential diagnosis of benign and malignant breast cancer. CT has a higher classification rate of breast cancer. Clinical according to the actual situation of patients choose the appropriate diagnostic methods to improve the detection rate of breast cancer.
