MRI artifact simulation for clinically relevant MRI sequences for guidance of prostate HDR brachytherapy.

This study demonstrated that the MRI artifact
 induced by an HDR source or a titanium needle could be simulated for the four investigated types of MRI sequences (spoiled gradient echo, spin echo, bSSFP and bSSFP-SPAIR), valuable for real-time object localization in clinical practice. This leads to more flexibility in the choice of MRI sequences for guidance of HDR brachytherapy, as they are suitable for both object localization and anatomy visualization.
