  •   objective  To investigate the value of MRI diagnosis of nodular breast benign and malignant lesions.   Methods  Retrospective analysis of 71 patients with nodular breast disease confirmed by pathology in our hospital, Perform MRI multi-parameter imaging before surgery, Select DCE-MRI and DWI for analysis, After processing: TIC time-signal curve, peak time, peak enhancement rate, SImax peak and ADC apparent diffusion coefficient, Combined with morphological characteristics: rough edges, ring strengthening, edge burr sign and leaf leaf sign for analysis.  Results  43 malignant lesions, 28 benign lesions.There were 22 TIC time-signal curves of type I, with 17 cases of benign lesions and 5 cases of malignant lesions.There were 35 cases of type Ⅱ, of which 24 were malignant and 11 were benign.14 of type Ⅲ are all malignant lesions.The TIC time-signal curve types of benign and malignant lesions are different, and the difference is statistically significant (P < 0.05); The peak time, peak enhancement rate, SImax peak and ADC apparent diffusion coefficient of benign and malignant lesions were significantly different, and the difference was statistically significant (P < 0.05).  Conclusion  MRI dynamic enhanced scanning hemodynamic parameters, ADC combined with morphological features are of great value in the diagnosis of breast nodular benign and malignant diseases.
