Diagnostic Value Analysis of Dynamic Contrastenhanced Magnetic Resonance Imaging (DCE-MRI) combined with Diffusion Weighted Imaging (DWI) before Breast Cancer Surgery

摘要

Objective:The objective of this study was to investigate the diagnostic efficacy of pre-operative magnetic resonance imaging(MRI)–dynamic contrast imaging(dynamic contrast-enhanced[DCE]-MRI)combined with diffusion-weighted imaging(DWI)in detecting breast cancer.Research Methodology: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 DCEMRI combined with DWI was significantly higher than ultrasound(91.0%vs.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:Pre-operative application of DCE-MRI combined with DWI can provide a more accurate and effective reference for surgical planning.
