Intensity Modulated Radiation Therapy Care

Planning for IMRT is complex and generally takes 2-5 days. Planning may include:

• Physical exam
• Coming in one or more times for imaging tests to identify exactly where the radiation beams will be focused; imaging tests used may include:
  • X-ray-a test that uses radiation to take a picture of structures inside the body
  • CT scan -a type of x-ray that uses a computer to make pictures of structures inside the body
  • MRI scan -a test that uses magnetic waves to make pictures of structures inside the body
  • PET scan -a test that uses a special camera to view structures inside the body after a radioactive solution is injected into a vein
  • CT/PET scan-a simultaneous fusion of both studies that provides increased accuracy over either study alone
• Marking the locations on the skin where the radiation will be focused to guide the therapist
• Being fitted for a localization device (eg, mask, body frame), which can help target accuracy
• Using ultrasound or implanted markers to track the position of the tumor

Using the marks made on your skin as a guide, the radiation therapist will position you on the treatment table. Films or ultrasound may be used to check the accuracy of the treatment setup. Then the therapist leaves the room to control the movements of the radiation machine. The treatment delivers radiation in a three-dimensional manner. This will help to conform as closely as possible to the shape of the tumor. The healthy tissue receives smaller doses of radiation than the tumor.

You will be asked to remain still during the radiation treatment. You may breathe normally. In general, you will not feel or sense anything during treatment. However, the machine can be stopped if you feel sick or uncomfortable. The therapists will be monitoring you on a TV camera. You will be able to communicate to them should you need to.

You will be able to leave and resume your normal daily activities. Receiving IMRT does not make you radioactive, and you do not need to avoid being around other people because of the treatment.

Each session will take 15-30 minutes. Patients are typically scheduled for IMRT five days per week for 4-8 weeks.

Holding one position may become a little uncomfortable, but it is not painful.

During treatment, your doctor will want to see you at least once a week. You may have blood tests or other studies performed.

After your treatment is completed, you will come in for regular visits to monitor for side effects and healing and check for signs of recurrent disease. You may require further testing, medicine, or rehabilitative treatment. Be sure to follow your doctor's instructions .
