Low Dose Rate (LDR) Brachytherapy
Low Dose Rate (LDR) Brachytherapy involves the implant or the insertion of a radioactive source(s) in or around the tumor site. The implant may be temporarily or permanently inserted depending on the type of cancer. At Houston Methodist Hospital we utilize LDR Brachytherapy for treatment of prostate cancer, gynecological cancers, eye and various other tumors. LDR Brachytherapy can also be used in conjunction with external beam therapy.
High Dose Rate (HDR) Remote After-Loader Brachytherapy
HDR procedures involve the placement of a radioactive source in or near the area to be treated. HDR brachytherapy delivers a large dose of radiation in a short period of time, so treatment delivery takes only a few minutes. The radiation dose is shaped by a computer that changes the position of the radiation source, which is housed in catheters or specialized devices. The advantage of using HDR is that the radiation is highly localized, sparing normal tissue from the effects of radiation. Most HDR procedures at Houston Methodist Hospital are performed on an outpatient basis. Some of the HDR services that we provide include breast, gynecological and pulmonary irradiation. See Partial Breast Irradiation for more.
