Case series analysis of post-brachytherapy prostate edema and its relevance to post-implant dosimetry. Post-implant prostate edema and dosimetry.

Purpose: We evaluated the post-operative pattern of prostate volume (PV) changes following prostate brachytherapy (PB) and analyzed variables which affect swelling.

Material And Methods: Twenty-nine patients treated with brachytherapy (14) or combined brachytherapy and external beam radiotherapy modality (15) underwent pre- and post-implant computed tomography (CT). Prostate volume measurements were done on post-operative days 1, 9, 30, and 60.

Real-time intraoperative computed tomography assessment of quality of permanent interstitial seed implantation for prostate cancer.

Objectives: To evaluate the use of real-time kilovoltage cone-beam computed tomography (CBCT) during prostate brachytherapy for intraoperative dosimetric assessment and correcting deficient dose regions.

Methods: A total of 20 patients were evaluated intraoperatively with a mobile CBCT unit immediately after implantation while still anesthetized. The source detector system was enclosed in a circular CT-like geometry with a bore that accommodates patients in the lithotomy position.
