brachytherapy

 [brak″e-ther´ah-pe]
internal radiation therapy using a radioactive source placed either within the body or a cavity, on the body surface, or a short distance from the surface.

brach·y·ther·a·py

(brak'ē-thār'ă-pē),
Radiotherapy in which the source of irradiation is placed close to the surface of the body or within a body cavity; for example, application of radium to the cervix.

brachytherapy

/brachy·ther·a·py/ (-ther´ah-pe) treatment with ionizing radiation whose source is applied to the surface of the body or within the body a short distance from the area being treated.

brachytherapy

(brăk′ē-thĕr′ə-pē)
n. pl. brachythera·pies
Radiotherapy in which the source of radiation is placed close to the surface of the body or within a body cavity.

brachytherapy

Etymology: Gk, brachys, short, therapeia, treatment
the placement of radioactive sources, such as seeds, needles, or catheters, in contact with or implanted into the tumor tissues to be treated for a specific period. Sources can be temporary or permanent. The rationale for this treatment is to provide a high absorbed dose of radiation in the tumor tissues and a very limited absorbed low dose in the surrounding normal tissues. Traditional brachytherapy implants deliver low doses of radiation; the newest variations deliver high doses. Compare teletherapy.
Radiation therapy in which radioactive materials­—iridium-192, radium-226, and other radioisotopes—sealed in needles, seeds, wires, or catheters are placed in direct contact with certain carcinomas to deliver locally intense ionising radiation—e.g., as needed in invasive carcinoma of the uterine cervix

brachytherapy

Implant radiation, internal radiation, intracavitary therapy, interstitial radiation therapy Radiation oncology RT in which radioactive materials–iridium-192, radium-226, and other radioisotopes, sealed in needles, seeds, wires, or catheters are placed in direct contact with certain carcinomas to deliver locally intense ionizing radiation–eg, as needed in invasive CA of the uterine cervix. See Intravascular brachytherapy.

brach·y·ther·a·py

(brak'ē-thār'ă-pē)
Radiotherapy in which the source of irradiation is placed close to the surface of the body or implanted in the tissues to be treated (e.g., application of radium to the cervix). Treatment targets specific tissues without harm to the surrounding normal tissue.

brachytherapy

A form of RADIOTHERAPY in which sealed sources of radioactive material are inserted for various periods into body cavities or directly into tumours, so as to lie as close as possible to the area to be radiated.

Brachytherapy

A type of radiation treatment for cancer in which the source of the radiation is applied directly to the surface of the body.

brachytherapy (braˈ·ki·theˑ·r·pē),

n ionizing radiation applied at a short distance from the body or directly to the surface.

brachytherapy

a form of radiotherapy in which the source of radiation is applied in or on the patient in one prolonged dose, using surface applicators, needles, seeds or suspensions for use in serous cavities.
