What Is IMRT?

Radiation therapy is a method of treating cancer with ionizing radiation. Refers to topical effects on the tumour. Radiation therapy is carried out on special equipment in the form of a medical linear accelerator, which supplies a directed stream of elementary particles to a predetermined area of ​ ​ exposure.

The specialist selects the required type of radiation taking into account the following parameters:

• Type of malignant neoplasm;
• The size of the tumour, its location in the body;
• How close the tumour is to healthy tissues that are sensitive to radiation;
• The general health of the body;
• Whether the patient has previously received treatment with other methods;
• Age and other factors.

A radiologist at Tel Aviv Medical Clinic is involved in the diagnosis and treatment of diseases with ionizing radiation. The specialist provides the patient with optimal care and develops an individual rehabilitation program after the procedure.

What Is IMRT?

Intensity-modulated radiation therapy (IMRT) is an advanced type of radiation therapy used to treat cancer and noncancerous tumours. The three-dimensional radiotherapy technique is used to treat patients with primary and secondary tumours of the central nervous system, allowing ionizing radiation to more accurately adapt to the tumour. At the same time, very accurate distribution of the dose of ionizing radiation around the target (tumour) of a complex form is created, its entire volume is outlined and shaded with a high dose of radiation. The use of IMRT allows maximizing the amount of radiation that can be obtained by healthy tissues located around the tumour with the ability to safely deliver higher doses of radiation to the tumour.

Side effect

As a result of radiation, healthy tissues can suffer and local reactions can occur. Such effects of irradiation are called local. These include dryness and peeling of the skin, increased fragility of the vessels at the irradiation site, small-hour haemorrhages, radiation burns of the skin up to the formation of ulcers.

Systemic consequences are due to the decay of the tumour after irradiation and the general intoxication of the body with decay products. In this case, weakness, fatigue, nausea and vomiting appear, hair often falls out, nails become brittle, blood indicators change, hematopoiesis is suppressed. All manifestations are temporary and pass as the body recovers.
