Analysis on the Application Value of DCE-MRI in the Differential Diagnosis of Benign and Malignant Breast Tumors in Young Women
Objective To analyze the value of dynamic contrast-enhanced magnetic resonance imaging(DCE-MRI)in the differential diagnosis of benign and malignant breast tumors in young women.Methods 98 young female patients with breast lesions were examined by DCE-MRI.The sensitivity,specificity and accuracy of DCE-MRI in the differential diagnosis of benign and malignant breast tumors were analyzed with pathological diagnosis as the gold standard.According to the pathological results,the DCE-MRI parameters of benign and malignant breast tumors were compared.Results The results of pathological diagnosis showed that 127 breast nodules were detected in 98 patients with breast lesions,including 88 benign nodules and 39 malignant nodules.The sensitivity,specificity and accuracy of DCE-MRI in differential diagnosis of benign and malignant breast tumors in young women were 96.59％,53.85％and 83.46％,respectively.The SER of the benign lesion group was lower than that of the malignant lesion group,and the Tmax,PER and ADC value were higher than those of the malignant lesion group(P＜0.05).Conclusions DCE-MRI has certain value in the differential diagnosis of benign and malignant breast tumors in young women.The lesions can be qualitatively diagnosed by parameters such as Tmax,PER and ADC.
