Purpose:
It is generally recognized that the optimum time to obtain a post-implant CT scan of an I-125 prostate implant is 30-50 days post-implant when the edema nearly resolved. However, logistical considerations often necessitate basing the post-implant dosimetry on a CT scan obtained on the day of the implant (day 0). The objective of this investigation is to determine the impact of the timing of the post-implant CT scan on the assessment of dose coverage and to define equivalent standards for implant quality on day 0 and day 30.
