Displacement patterns of stranded I-125 seeds after permanent brachytherapy of the prostate: Dosimetry in the operating room put into perspective.

CONCLUSIONS: There were substantial changes in dose distribution 1month after the procedure, mainly due to implant and prostate shrinkage and displacement of ventral seed strands in caudal direction. When performing dynamic dosimetry or dosimetry at the end of the procedure the effect of these phenomena has to be taken into account when using stranded seeds.
