An MRI-based dose-response analysis of urinary sphincter dose and urinary morbidity after brachytherapy for prostate cancer in a phase II prospective trial

Doses to the IUS and EUS on MRI/CT predicted worse urinary function, with greater bother, irritative symptoms, and urgency. Incorporating MRI-based dose-volume histogram analysis into the treatment planning process may reduce acute urinary morbidity after brachytherapy.
