Synopsis

Keywords: Breast, Data Analysis, Conventional DCE-MRI, ultrafast DCE-MRI, quantitative parameters, semiquantitative parametersThe conventional dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) technique has been shown to be very sensitive in detecting benign and malignant breast cancer lesions. However, it requires a relatively long acquisition time and hence a semiquantitative imaging technique. To reduce the acquisition time, ultrafast DCE-MRI techniques have been proposed for breast tumor imaging. Our study aims to investigate the feasibility of the ultrafast DCE-MRI technique in differentiating benign and malignant breast tumors. The results show that the semiquantitative and quantitative parameters obtained with ultrafast DCE-MRI are superior to those obtained with conventional DCE-MRI in differentiating benign and malignant breast tumors.
