The Lourdes Regional Cancer Center has a new tool in it's cancer fighting arsenal, Intensity Modulated
Radiation Therapy. IMRT is a type of three-dimensional radiation therapy that improves the targeting
of radiation therapy treatments, decreasing damage to normal tissues. This noninvasive procedure pinpoints
the delivery of radiation to the patient by using a computer system to change the intensity of radiation
beams, creating a clinically optimal treatment plan - one that maximizes the dose to the tumor while
sparing the surrounding tissues.
Intensity Modulated Radiation Therapy is the most technologically advanced treatment method available
in external beam radiation therapy. IMRT uses computer-generated images to match a radiation dose to
the size and shape of a patient's tumor. Rather than having a single large radiation beam pass through
the body, with IMRT, the radiation is effectively shaped in order to conform to the size and shape of
the tumor. With laser accuracy, these beams enter the body from many angles and target the cancer. This
results in a high dosage of radiation to the tumor and a lower dosage to the surrounding healthy tissues.
IMRT is performed on an outpatient basis. It is most beneficial for patients who need high-dose radiation
therapy in areas closely located to sensitive or essential organs, but all types of cancer can benefit
from IMRT.
