High-Dose Rate Radiation Therapy

High-dose rate implants are used for prostate and many other types of cancer.

A small radioactive source at the end of a wire can be inserted into various applicators or catheters.

In order to treat prostate cancer, a Urologist and Radiation Oncologist use ultrasound to help place about a dozen catheters into the prostate gland. A CT scan is given to develop a specific computer plan that varies the length of time the radioactive source is in each catheter.

The patient is given two separate treatments, and frequently it requires an overnight stay in the hospital.
