Image Guided Brachytherapy (IGBT)
Brachytherapy is a mode of cancer treatment that involves the insertion of radioactive implants directly into the tumor, thereby allowing the delivery of higher doses of radiation to tumors while sparing toxicity to surrounding normal tissues. It is commonly used as an effective treatment for cervical, head and neck, endometrial, vaginal, breast, esophageal, skin, and sarcomas.
Historically, 2-dimensional brachytherapy utilized X-ray based treatment planning. With the evolution of Image Guided Brachytherapy (IGBT) and the utilization of CT/MRI/PET CT for target delineation and planning, there was better local control and a reduction in side effects.
