Active Contrast Encoding MRI (ACE-MRI) is a recently proposed method to conduct DCE-MRI experiment without the need to perform separate T1 and B1 measurement. The purpose of this study is to further investigate the feasibility of using the ACE-MRI method for evaluation of tumor treatment response in a mouse model of breast cancer. The results of the ACE-MRI method were compared with conventional DCE-MRI data analysis with separately measured T1 maps. Our preliminary results demonstrate that the ACE-MRI method can be used to evaluate tumor treatment response reliably.
