What is IMRT used to treat?
IMRT is used at MSK most often to treat prostate cancer, head and neck cancers, lung cancer, brain cancer, gastrointestinal cancers, and breast cancer, in part because these tumors tend to be located close to critical organs and tissues in the body.
Does IMRT hurt?
IMRT doesn’t hurt. You shouldn’t feel anything during treatment. But the machine will be noisy.
What type of radiation is used in IMRT?
A medical linear accelerator (LINAC) generates the photons, or x-rays, used in IMRT. The machine is the size of a small car—approximately 10 feet high and 15 feet long. During the treatment, the patient must lie still. The intensity of each beam’s radiation dose is dynamically varied according to treatment plan.
How is IMRT administered?
IMRT typically is administered five days a week for five to eight weeks. For each session, the patient is in the treatment room for 15 to 30 minutes. Small amounts of radiation given on a daily basis, rather than a few large doses, help to reduce damage to body tissues surrounding the tumor.
How much does IMRT radiation cost?
Results. Mean utilities for patients receiving CRT were 0.802 (standard deviation 0.221) while the mean utilities for patients receiving IMRT were 0.901 (standard deviation 0.112). The expected mean cost of patients undergoing IMRT was $52,170 with a survival of 7.62 quality-adjusted life years (QALY).
How long does IMRT last?
How Long Does IMRT Treatment Last? IMRT is usually given to you five days a week for four to eight weeks. The total dose of radiation and the number of treatments you need will depend on the size of your prostate cancer, your general health, and other medical treatments you may need.
What are the two types of radiation therapy?
There are two main types of radiation therapy, external beam and internal.
What kind of radiation therapy does IMRT use?
Intensity-modulated radiation therapy (IMRT) is an advanced mode of high-precision radiotherapy that uses computer-controlled linear accelerators to deliver precise radiation doses to a malignant tumor or specific areas within the tumor.
How does image guided radiation therapy ( IGRT ) work?
Image-guided radiation therapy (IGRT) Print. Image-guided radiation therapy (IGRT) is a method of radiation therapy that incorporates imaging techniques during each treatment session. Radiation therapy uses high-energy beams of radiation to control cancer and noncancerous tumors.
How is intensity modulated radiation therapy used to treat cancer?
Intensity-modulated radiotherapy (IMRT) uses linear accelerators to safely deliver precise radiation to a tumor while minimizing the dose to surrounding normal tissue. Your radiation oncologist will speak with you to determine whether IMRT is the most appropriate treatment for you. What is Intensity-Modulated Radiation Therapy and how is it used?
How is radiation therapy used to treat cancer?
Radiation therapy, including IMRT, damages the DNA and stops cancer cells from dividing and growing, thus slowing or stopping tumor growth. In many cases, radiation therapy is capable of killing all of the cancer cells, thus shrinking or eliminating tumors. Radiation therapy may be used in conjunction with surgery (adjuvant radiation).
