What is Tandem brachytherapy?
Brachytherapy for gynecological cancers can be done using a “tandem and ovoid” (T&O) applicator or a “tandem and ring” (T&R) applicator. The tandem is a long, thin metal tube that is passed through the cervix, into the uterus. The ovoids are circular hollow capsules, and the ring is a hollow ring.
What are the three types of brachytherapy?
Sure, there are 3 types of brachytherapy: low-dose rate implants, high-dose rate implants, and permanent implants. Low-dose rate implants, often called LDR for short, are implants that stay in for 7 days or less before they are taken out.
What are the two types of brachytherapy?
There are two main forms of brachytherapy – intracavitary treatment and interstitial treatment. With intracavitary treatment, the radioactive sources are put into a space near where the tumor is located, such as the cervix, the vagina or the windpipe.
What is the difference between interstitial and intracavitary brachytherapy?
There are different types of brachytherapy. Intracavity brachytherapy involves placing the radioactive seeds inside a natural body cavity, such as the windpipe, vagina, or rectum. Interstitial brachytherapy involves surgically implanting the radioactive seeds into or near a cancer tumor, such as in the prostate.
What isotope is used in brachytherapy?
Currently, the isotope most commonly used for temporary brachytherapy is iridium (Ir)-192, which provides a higher dose of radiation than the iodine (I)-125 and palladium (Pd)-103 permanent implants.
How is cobalt 60 used in radiation treatment?
Co-60 is used medically for radiation therapy as implants and as an external source of radiation exposure. It is used industrially in leveling gauges and to x-ray welding seams and other structural elements to detect flaws. Co-60 also is used for food irradiation, a sterilization process.
