Correlation Between Pre- and Postimplant Dosimetry for Iodine-125 Seed Implants for Localized Prostate Cancer

In this study, we showed that there is a strong correlation between transrectal ultrasound-based preimplant and CT-based postimplant dosimetry. The excellent correlation between prostate D90 and V100 values demonstrates they are both equally valid quality indices. Vi parameters are an additional measure that can be used to assess the quality of the implant.
