Meta-analysis of diagnostic accuracy of magnetic resonance imaging and mammography for breast cancer.

Objective: The aim of this study was to compare the performance of mammography (MG) and magnetic resonance imaging (MRI) in the diagnosis of breast cancer. Methods: Searching in the databases including PubMed, Embase, and Google Scholar about comparative study of MG and MRI in the diagnosis of breast cancer during 2000-2017. After we screened further, the extracted effective data were calculated by Meta-Disc 1.4 software. Results: we obtained 11 articles. The pooled estimates for sensitivity of MG and MRI were 0.75 (95% confidence interval [CI], [0.72, 0.78]) and 0.92 (95% CI, [0.89, 0.94]) respectively, and for specificity were 0.71 (95% CI, [0.67, 0.74]) and 0.70 (95% CI, [0.66, 0.73]), respectively. Their weighted area under the summary receiver operating characteristic curve was 0.79 and 0.93, respectively. Conclusion: MRI remains to be a satisfactory method for the diagnosis of breast cancer and should first be considered for patients.
