IGRT Radiation Therapy: An Overview and Standard of Care

Image-Guided Radiation Therapy (IGRT) is an advanced form of therapy that incorporates imaging technology during radiation treatment. Imaging encompasses various methods for capturing pictures of the inside of the body.

IGRT enables the delivery of precise radiation doses to a malignant tumor or specific areas within the tumor with high accuracy. This precision is crucial for sparing surrounding healthy tissue from high radiation exposure, thereby reducing side effects.

Several types of IGRT technologies and techniques are currently in use:

  • Cone Beam CT: Provides a 3D image set.
  • MVCT: Stands for megavoltage computed tomography.
  • Ultrasound: Utilizes high-frequency sound waves to create images.
  • Implanted Fiducial Markers: Tiny metallic objects placed inside or near tumors to aid in precise targeting.

In the realm of cancer treatments, IGRT is recognized for its targeted approach and effectiveness in managing complex cancers while minimizing damage to healthy tissues.

All treatment options present a balance of benefits and risks.

Choosing and Expecting from IGRT Treatment

Image-Guided Radiation Therapy (IGRT) is a type of radiation therapy for cancer that leverages advanced imaging technology to enhance the precision in targeting tumors.

The consideration of IGRT involves evaluating its potential benefits and risks, along with alternative treatments such as surgery or chemotherapy.

The objective of IGRT is to accurately target cancer cells while minimizing damage to healthy tissue. Treatment sessions typically range from 15-30 minutes and may extend over several weeks.

Side effects are possible with IGRT, although they often diminish after the completion of treatment. Understanding these aspects is crucial for evaluating this treatment option.

Advantages and Techniques of IGRT

Image-Guided Radiation Therapy (IGRT) utilizes imaging technology during radiation therapy to deliver precise radiation doses to malignant tumors.

Advantages of IGRT

  • Precision: IGRT enables the visualization of the tumor at each treatment session, enhancing the accuracy of the therapy.
  • Safety: This technique allows for the delivery of higher doses of radiation to tumors while minimizing exposure to healthy tissues.
  • Adaptive treatment: Treatment plans can be adjusted based on changes in the size or location of the tumor.

Techniques of IGRT

There are several techniques for performing IGRT:

  • CT scan-based: CT scans are taken just before or during radiotherapy sessions to guide treatment.
  • X-ray-based: Two X-ray images from different angles are used to accurately position the patient for treatment.
  • Ultrasound-Based: Ultrasonic images are utilized to guide the delivery of radiotherapy.

In conclusion, IGRT represents a method for treating malignant cells with a focus on minimizing damage to surrounding healthy tissues.
