HDR BrachytherapyWhat is High Dose Rate Brachytherapy (HDR)?High dose rate brachytherapy is a form of internal radiation where high doses of radiation are delivered quickly during an outpatient procedure. In HDR, catheters are placed in or adjacent to the cancer tissue after which a computer driven apparatus, called a remote afterloading device, pushes the radiation source through the catheters to the tumor site. The source remains in place for a predetermined amount of time. When the desired dose has been achieved, the remote afterloading device withdraws the radioactive source.

How do I prepare for HDR Brachytherapy?The exact preparation for the treatment may depend on the site receiving the radiation. The physician and other members of the treatment team will provide each patient with specific instructions prior to treatment.

Some HDR brachytherapy treatments are delivered only once, whereas other treatments may require the patient to come in once or twice a day for a period of one or more weeks.
