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.
