ABSTRACT
Objective To investigate the MRI features and characteristics of irregular intraductal papilloma (IDP)and invasive ductal carcinoma (IDC),and to improve the diagnostic accuracy of MRI.Methods This study retrospectively included 3 3 patients with IDP and IDC confirmed by surgery and pathology,and analyzed MRI findings including lesion size,boundary,internal components,plain signal intensity,enhancement mode,ADC value and TIC curve χ.2 test,t test and rank-sum test were performed.Results Compared with the two groups,lesion boundary (P<0.001),size (P<0.001 ),ADC value (P<0.001 ),enhancement mode (P=0.001 ),TIC curve peak time (P<0.001),slope (P<0.001)and peak enhancement rate (P<0.001)were statistically significant (P<0.05);lesion (P=0.159), internal components (P=0.778),T2 WI signal (P=0.438)and curve type (P=0.406)were no statistically difference.Conclusion The irregular mass type IDP and IDC have similar MRI findings,the edge of the lesion,the ADC value,the enhancement mode,and the peak time,slope and peak enhancement rate of the curve are important for the identification of the two diseases.
