Semi-automatic ROI registration and texture feature extraction for pre- and post- neoadjuvant chemotherapy contrast-enhanced MR in predicting response of mass-like breast cancers

In mass-like breast cancers, semi-automatic ROI registration from pre- to post-treatment MR images, and combined with usage of texture feature extraction for automatically segmentation of enhanced areas, the ability for predicting residual tumors after neoadjuvant chemotherapy can be improved significantly and cost lesser time in imaging reading.
