Abstract:
Objective To discuss application of dynamic contrast-enhanced MR scan combined with DWI in diagnosis of benign and malignant breast disease. Methods A total of 71 cases with breast disease and 50 healthy volunteers were selected. All subjects received MRI conventional scanning, conventional scanning and DWI, sensitivity, specificity, the positive predictive value and the negative predictive value of different methods for diagnosis of benign and malig-nant breast disease. Results MR morphology in diagnosis of benign and malignant breast disease, sensitivity was 90.0%, specificity was 73.7%, the positive predictive value was 78.3%, the negative predictive value was 87.5%. Dy-namic contrast-enhanced MR scan in diagnosis of benign and malignant breast disease, sensitivity was 92.5%, speci-ficity was 66.4%, the positive predictive value was 74.0%, the negative predictive value was 89.3%. Dynamic con-trast-enhanced MR scan combined with DWI and MR morphology in diagnosis of benign and malignant breast disease, sensitivity was 95.0%, specificity was 89.5%, the positive predictive value was 90.5%, the negative predictive value was 94.4%. Conclusion Dynamic contrast-enhanced MR scan combined with DWI and MR morphology in diagnosis of benign and malignant breast disease can improve sensitivity, specificity, the positive predictive value and the negative predictive value.
