MRI in clinical diagnosis of breast tumours

Objective To explore MRI(magnetic resonance imaging) for the diagnosis of breast tumours.Methods A retrospective analysis of MRI characters of 99 patients with breast tumors was made to differentiate benign from malignant breast lesions.Results Compared with postoperative pathology result,the MRI examination of the 99 patients showed malignant lesion in 54 patients,benign lesion in 43 cases,and 2 cases were misdiagnosed.The diagnosis rate was 98%.Conclusion By MRI,occult early and small breast carcinoma can be detected,and malignant lesion of dense breast can also be identified.MRI can raise the rate of diagnosis and is helpful in preoperative staging of breast cancer.It is an important complementarity in breast examination.
