It is important to improve ghost correction in breast DWI using SE-EPI because residual ghosts bias ADC measurements, which reflect malignancy. The standard ghost correction method using a 3-line navigator frequently fails in breast DWI. In this work we implemented several alternative ghost correction strategies. The two best methods outperformed the standard 3-line navigator correction. These techniques applied 1D, linear corrections based on 1) phase maps from separate reference scans and 2) entropy minimization.
