Magnetic Resonance Image for Diagnosis of Breast Lesions

Objective To evaluate the application value of MRI in diagnosis of breast lesion.Methods 63 female patients with suspected breast lesion underwent X-ray mammography,breast infrared diaphany,plain and contrast-enhanced MRI examination,and then all of them received surgery treatment and pathologic examination.Results Among 63 cases,two cases of non-breastdisease,which were misdiagnosed by the three tranditional methods,were identified by MRI.Contrast-enhanced MRI had the sensitivity, specificity and overall accuracy being respectively 91.4%,96.2%,92.0% in terms of benign and malign lectiferous glands tumor,and Plain MRI presented an accuracy of 79.3% in terms of breast disease.X-ray mammography,ultrasound and breast infrared diaphany had an accuracy of 66.7%,67.8% and 56.3% respectively.Conclusion As far as diagnosis of breast lesions is concerned,contrast-enhanced MRI is superior to other methods and plain MRI presents no significant difference compared with X-ray and ultrasound,but it is better than infrared diaphany.
