The purpose of our study is to determine the correlation between the parameters obtained from ultrafast dynamic contrast-enhanced (ultrafast DCE) MRI and prognostic factors of breast cancer.
Fifty five breast cancers were included in this study. Ultrafast DCE sequence was performed using higher than usual parallel imaging factor and obtained with 8.3 second temporal resolution. Kinetic parameters obtained from ultrafast DCE were compared with prognostic factors.
Mean maximum slope of invasive cancer (10.2) was significantly higher than that of DCIS (8.2).
Ultrafast DCE MRI is useful for differentiating DCIS and invasive breast cancer.
