PDFAbstract
Objective To explore the sensitivity and specificity of MR dynamic enhancement curve, diffusion weighted imaging (DWI) and apparent diffusion coefficient (ADC) value in the qualitative diagnosis of breast diseases. Methods 30 cases (30 lesions) of patients with suspected breast masses were collected from the hospital from June 2014 to June 2015. All cases were confirmed by surgery and pathology. Among them, 17 cases were benign lesions and 13 were malignant ones. The accuracy, sensitivity and specificity of MR dynamic enhancement curve, ADC value and combined diagnosis in diagnosis of breast diseases were statistically analyzed. Results With histopathology as the golden standard, the accuracies of MR dynamic enhancement curve, ADC value and combined diagnosis were 76.67%, 80.0% and 90.0%, respectively. The sensitivities were 84.62%, 84.62% and 92.31%, respectively. The specificities were 70.59%, 76.47% and 88.24% respectively. Conclusion MR dynamic enhancement curve and ADC value combined diagnosis in the diagnosis of breast diseases can improve the accuracy and specificity of diagnosis.
