Intensity-Modulated Radiation Therapy (IMRT)
IMRT, or intensity-modulated radiation therapy, is an advanced form of radiation treatment for cancer. It uses carefully customised beams of radiation that match the shape of the cancer. These beams can move around and adjust their intensity during treatment. The aim is to precisely target the cancer while minimising damage to surrounding healthy tissue. IMRT can be used to treat both cancerous tumours and non-cancerous ones throughout the body.
At Apollo Cancer Centre, Hyderabad, intensity-modulated radiation therapy offers patients a wider range of treatment choices and greatly improved results. Our dedicated doctors are focused on providing personalised medical care, using advanced technology to speed up recovery and support overall health.
Why Choose Intensity-Modulated Radiation Therapy (IMRT)?
- Utilising advanced technology, intensity-modulated radiation therapy (IMRT) targets cancer cells with remarkable precision, minimising harm to nearby healthy tissue.
- By precisely sculpting radiation beams, IMRT shields vital organs from unnecessary exposure, reducing the likelihood of adverse side effects. This precision is especially crucial when treating tumours adjacent to critical structures such as the brain or spinal cord.
- Sparing healthy tissue from radiation damage, IMRT not only enhances treatment effectiveness but also improves patient safety and quality of life.
Consequently, IMRT is often considered a preferable option for patients requiring treatment near essential organs.
Pre-Operative Care For Intensity-Modulated Radiation Therapy (IMRT)
- Before starting treatment, the doctor will examine the patient and check their medical history. A session is held to simulate the treatment plan, often using a CT scan. A small mark or tattoo might be placed on the skin to guide the equipment during treatment. The radiation doctor uses the scan to create a personalised plan. Sometimes, a mask or device is made to keep the patient still during treatment.
- The patient might need to follow special instructions, like fasting or preparing their bowels and bladder before the simulation and treatment. Sometimes, a dye is injected during the CT scan to help see the tumour better.
- Occasionally, more scans like PET or MRI might be needed to plan the treatment accurately. These images are combined with the CT scan to pinpoint the tumour’s location.
- In some cases, markers are inserted into the target area for better positioning. Usually, IMRT treatment starts about a week or two after the simulation.
What Happens In Intensity-Modulated Radiation Therapy (IMRT)?
- IMRT treatment is usually not completed in just one session. It is a process that involves multiple treatment sessions spread out over several days. The radiation oncologist determines the number of sessions based on various factors, including the type and location of the tumour, the required radiation doses, and the overall health condition of the patient. Typically, patients undergo IMRT sessions five days a week for a duration of five to eight weeks.
- Before each treatment session, the patient is carefully positioned on the treatment table. This positioning is guided by marks on their skin or any devices that were created earlier to assist in maintaining the correct position. Throughout the procedure, adjustments may be made to ensure precise targeting of the tumour area. Imaging systems, such as X-rays or CT scans, may also be used to verify the patient’s position and the location of any markers.
- IMRT sessions can vary in duration, typically lasting between 15 to 60 minutes. During this time, the patient remains on the treatment table while the radiation therapy is administered. The process is carefully monitored to ensure accuracy and effectiveness in targeting the cancerous cells while minimising damage to surrounding healthy tissue.
Post-Operative Care For Intensity-Modulated Radiation Therapy (IMRT)
- The outpatient nature of IMRT offers several benefits to patients. Being able to go home after treatment allows individuals to resume their normal daily activities and routines, contributing to their overall comfort and well-being. It also reduces the inconvenience and disruption that may be associated with prolonged hospital stays.
- Before leaving the medical facility, patients may receive instructions or guidance from their healthcare team regarding any potential side effects or precautions to take following treatment. This ensures that patients are well-informed and prepared for their recovery process at home.
