Abstract:
Objective To investigate the optimal combination and the value of functional magnetic resonance imaging in the diagnosis of breast tumors. Methods One hundred and forty patients who had been clinically and pathologically diagnosed as breast tumors in our hospital during the period of 2009 to 2013 were collected. 63 of whom had breast cancer and 77 had benign tumor. All the patients received 1H-MRS, DWI and dynamic enhanced MRI at the same time. The obtained images were analyzed and then compared with the pathological findings. The accuracy, sensitivity, and specificity of MRS combined with DWI or dynamic enhanced MRI, or DwI combined with enhanced MRI in the diagnosis of breast cancer were obtained. Results All the diagnosis were pathologically confirmed. The accuracy, sensitivity, and specificity were 89.8%, 90.1%, and 90.0% for DWI combined with dynamic contrast-enhanced MRI; 77.9%, 77.3% and 79.3% for MRS in combination with enhanced MRI; and 76.3%, 77.8% and 77.1% for DWI combined with MRS. There were significant differences among the three kinds of combination detection in diagnosis of breast cancer , χ2= 9.057, P = 0.011. Conclusions The sensitivity, specificity and accuracy is the highest in DWI combined with dynamic enhanced MRI in the diagnosis of breast tumor , which can be used as the best combination imaging for breast tumor.
