Breast neoplasms are the most common cancer among women. Whether received adjuvant chemotherapy or not, lots of them presented cognitive impairment which decreased their quality of life. Therefore, we attempted to use generalized q-sampling imaging (GQI) to detect the white matter alteration between groups that may due to post-traumatic stress disorder (PTSD), post-traumatic growth (PTG) and chemotherapy.
