Sequential evaluation of prostate edema after permanent seed prostate brachytherapy using CT-MRI fusion

Conclusion: Despite the extreme range of postimplant edema, the effect on dosimetry was less than expected. Dose coverage of the prostate was good for all patients during Days 1-30. Our data indicate that postimplant dosimetry on the day of implant is sufficient for patients with good dose coverage (Day 1 V100 >93%).
