Diagnostic value of preoperative MRI dynamic contrast imaging (DCE-MRI) combined with diffusion-weighted imaging (DWI) in breast cancer detection

Abstract

Abstract Objective: To investigate the diagnostic efficacy of preoperative MRI dynamic contrast imaging (DCE-MRI) combined with diffusion-weighted imaging (DWI) in detecting breast cancer.Methods: A retrospective study was performed to compare the results of DCE-MRI combined with DWI in 78 patients with breast cancer who were treated in our hospital between January 20 and December 2018.  Results: After diagnosis, the coincidence rate of diagnosis by DCE-MRI combined with DWI was significantly higher than ultrasound (91.0% versus 55.1%, respectively; P< 0.05). Among the two diagnostic methods, DCE-MRI combined with DWI imaging showed more obvious tumor signals, and the difference was statistically significant (P<0.05).Conclusion: Preoperative application of DCE-MRI combined with DWI can provide a more accurate and effective reference for surgical planning.
