There are two types of brachytherapy – high dose-rate (HDR) and low dose-rate (LDR). LDR brachytherapy is the one most commonly used to treat prostate cancer. It may be referred to as 'seed implantation' or it may be called 'pinhole surgery'. In LDR brachytherapy, tiny radioactive particles the size of a grain of rice (Figure 1) are implante…
Webbavailable for prostate cancer, dependent on the radioactive source that is used. The first, low dose rate (LDR) brachytherapy, involves the insertion of radioactive seeds permanently into the prostate; the second, high dose rate (HDR) brachytherapy, involves the temporary insertion of a radioactive source into the prostate via implanted needles. WebbBrachytherapy planning, whether LDR or HDR, requires 3-dimensional (3-D) understanding of prostate size and shape, typically based on serial axial transrectal ultrasound images. Seed (or iridium source “dwell”) locations are designed to provide coverage of the prostate and 2 to 3 mm of extraprostatic tissue while partially sparing the urethra.
