PDFAbstract
Objective To study the clinical value of magnetic resonance imaging (MRI) in differential diagnosis of benign and malignant breast lesions. Methods A total of 85 patients with breast diseasesadmitted to the hospital between March 2013 and September 2016 were enrolled in the study. MRI plain scan and dynamic enhanced scanning were performed, and all patients were confirmed by pathology. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of MRI plain scan and MRI enhanced scan in the diagnosis of benign and malignant breast lesions were evaluated. Results The sensitivity, specificity and accuracy of MRI plain scan were 82.1%, 84.2% and 83.0%, respectively while of MRI were 92.9%, 94.7% and 93.6%, respectively. The diagnostic accuracy of MRI (93.6%) was higher thanMRI plain scan (83.0%) (χ2 =5.148, P<0.05). Conclusion The sensitivity and specificity of MRI are high in the diagnosis of benign and malignant breast lesions. Dynamic contrast-enhanced imaging can improve the morphological features of benign and malignant breast lesions and improve the diagnostic accuracy of MRI.
