Comparison of intraoperative ultrasound with postimplant computed tomography-dosimetric values at Day 1 and Day 30 after prostate brachytherapy

Our results demonstrate that there are no significant differences between the D90 assessments obtained intraoperatively and at Day 30 postoperatively. Furthermore, there are no definite correlations between intra- and postimplantation dosimetric values. Other D90 values differed significantly between the intraoperative and postimplant dosimetry. This study suggests that dosimetry has negligible clinical utility for informing patients, at discharge, of whether or not their implants are adequate.
