Brachytherapy

Low Dose Rate (LDR) Brachytherapy

Low Dose Rate (LDR) Brachytherapy involves implanting or the insertion of a radioactive source or sources in or around the tumor site. The implant may be temporary or permanently inserted depending on the malignacy. At Houston Methodist Hospital we utilize LDR Brachytherapy for treatment of prostate, gynecological, eye and various other tumors. LDR Brachytherapy can also be used in conjunction with external beam therapy.

High Dose Rate 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 which changes the position of the source 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.
