Brachytherapy, or internal radiation therapy, is a treatment option where a protected radiation source is placed directly within or near the tumor site with a special needle. Brachytherapy is sometimes called internal radiation therapy.
High Dose Rate (Brachytherapy)
High-dose rate (HDR) brachytherapy involves placing a protected source of high-energy radiation directly within the tumor. These radioactive materials are placed over the surface of the tumor, within the tumor or within a body cavity surrounded by the tumor, to deliver a high dose of radiation in a short period of time.
Prostate Seed Implant (PSI)
Prostate Seed Implant is a treatment procedure that implants permanent radioactive sources for the treatment of prostate cancer. The PSI procedure is typically performed by a team of both radiation oncologists and urologists and is considered a low-dose rate brachytherapy procedure.
