A low dose rate prostatic brachytherapy implant involves the insertion of radioactive pellets (seeds) directly into the prostate via a transperineal approach (the needles are inserted through the muscle between the scrotum and rectum).  These radioactive seeds slowly emit their radiation over a long period of time with a half life of approximately two month.  In other words the total radiation dose is usually delivered over a 10 month period (5 half lives). It is possible that the constant delivery of low dose radiation over this period of time may improve outcome, as the constant radiation dose does not allow … Continue reading Lose Dose Rate Prostatic Brachytherapy Implant
