Summary
Brief summary (as posted)
There are substantial uncertainties with contemporary seed placement techniques in prostate brachytherapy, particularly with the impact of seed movement after an implant due to edema and migration of seeds in the prostate and peri-prostatic tissues. This study will accrue 20 patients undergoing prostate brachytherapy implants and perform serial CT and MRI scans at specified intervals (pre-operatively, day 0, day 3, day 10 and day 28) to characterize these phenomena.
