Measuring Sparse Temporal-Variation for Accurate Registration of Dynamic Contrast-Enhanced Breast MR Images

Image registration is a vital process in the dynamic contrast-enhanced (DCE) magnetic resonance (MR) imaging based breast tumor diagnosis. DCE-MR imaging based examinations generally involves multi-times of imaging on the breast volume before and after the administration of a contrast agent, yielding the pre-contrast image and a series of post-contrast images. In DCE-MR images, tumor region can have various contrast enhancement patterns due to the agent, leading to significant temporal intensity changes.
