PDFAbstract
Objective To investigate the diagnostic value of mammography combined with dynamic contrast-enhanced MRI in breast diseases. Methods 62 cases of breast masses diagnosed by pathological examination were selected as subjects admitted to our hospital from June, 2015 to February, 2016. The patients were examined by mammography, MRI, MR enhancement and diffusion-weighted imaging. The imaging findings and diagnostic accuracy of molybdenum target X-ray and MRI were analyzed respectively. The diagnostic value of mammography combined with dynamic contrast-enhanced MRI was analyzed. Results The diagnostic accuracy of mammography was 43.35% (43/62). MRI diagnosis was performed in 57 patients with breast disease. The diagnostic accuracy was 91.93% (57/62) (P<0.05). The accuracy of the combined examination was 96.77% (60/62), which was higher than that of pure mammography and dynamic contrastenhanced MRI. The difference was statistically significant (P<0.05). Conclusion Dynamic contrast-enhanced MRI is more accurate than mammography, and mammography combined with dynamic contrast-enhanced MRI can improve the accuracy of breast disease diagnosis, which provides relevant imaging information for the clinical development of reasonable treatment plan.
