Overview: What is IGRT?
Image-Guided Radiation Therapy (IGRT) is an advanced form of radiation treatment that uses imaging technology to guide and deliver precise radiation doses to a tumor. Unlike conventional radiation therapy, IGRT allows doctors to see the tumor in real-time before and during each treatment session, ensuring that radiation is accurately targeted while minimizing exposure to surrounding healthy tissues.
IGRT is especially beneficial for tumors that:
- Move during treatment (due to breathing or natural organ motion)
- Are located near critical organs
- Are difficult to detect without advanced imaging
By using daily imaging (X-rays, CT scans, or MRI) before delivering radiation, oncologists can adjust the patient’s position and beam angles, improving accuracy and treatment outcomes.
How IGRT Works
- Patient Positioning – The patient lies on the treatment table in a specific position using immobilization devices to ensure accuracy.
- Imaging Before Treatment – High-quality images are taken to verify tumor location and size.
- Comparison with Planning Images – Images are compared with the original treatment plan to check for any shifts in tumor position.
- Adjustments – If the tumor has shifted due to breathing, weight loss, or organ movement, adjustments are made before radiation is delivered.
- Radiation Delivery – High-energy beams are directed precisely at the tumor, sparing healthy tissues.
Conditions Treated with IGRT
IGRT can be used for various cancers, especially when high precision is required. Common applications include:
- Brain Tumors (including benign and malignant)
- Head and Neck Cancers
- Prostate Cancer
- Lung Cancer
- Pancreatic Cancer
- Liver Cancer
- Gynecological Cancers (Cervical, Endometrial)
- Spinal Tumors
Benefits of IGRT
- High Accuracy – Real-time imaging ensures radiation is targeted exactly to the tumor.
- Better Tumor Control – Higher doses can be delivered without increasing side effects.
- Reduced Damage to Healthy Tissues – Lowers risk of complications in nearby organs.
- Fewer Side Effects – Less damage to healthy cells results in quicker recovery.
- Adaptability – Treatment plans can be modified mid-course if tumor size or shape changes.

Possible Side Effects of IGRT
While IGRT reduces side effects compared to conventional radiation, some temporary effects may still occur:

- Mild skin irritation
- Temporary hair loss in treated area

- Difficulty swallowing (for head and neck cancers)
Most side effects are manageable and resolve after treatment completion.

Frequently Asked Questions
FAQs
- What is IGRT and how is it different from regular radiation therapy?
IGRT is an advanced radiation therapy that uses daily imaging (X-rays, CT, or MRI) before and during each treatment session. This ensures the radiation beams are precisely targeted at the tumor, unlike conventional radiation therapy that relies on fixed positioning without daily imaging. - Who is a good candidate for IGRT?
IGRT is ideal for patients with tumors located near vital organs, tumors that move due to breathing (like in the lungs), or cancers where high precision is essential, such as brain, prostate, and head and neck cancers. - How many sessions of IGRT will I need?
The number of sessions depends on the type and stage of cancer. Most patients require daily treatments (Monday–Friday) for 5–8 weeks. Your oncologist will create a personalized schedule. - Is IGRT painful?
No. IGRT is a painless, non-invasive procedure. You will only feel the treatment table and positioning devices. The imaging and radiation delivery cause no discomfort. - What types of cancers can be treated with IGRT?
IGRT can treat many types of cancers, including brain tumors, prostate cancer, lung cancer, head and neck cancers, liver cancer, pancreatic cancer, gynecological cancers, and spinal tumors. - How should I prepare for an IGRT session?
Your care team may advise you to maintain a specific bladder or bowel condition before treatment (especially for prostate or pelvic cancers). Comfortable clothing and avoiding heavy meals before sessions are usually recommended. - What is the cost of IGRT in India?
IGRT costs in India range between ₹2,40,000 and ₹4,80,000 ($3,000–$6,000) for a full course, making it more affordable compared to the US or UK, without compromising on quality. - Are there any side effects of IGRT?
IGRT reduces side effects compared to older radiation methods, but some temporary effects like fatigue, mild skin irritation, nausea, or swallowing difficulty (depending on the treatment site) may still occur. - How accurate is IGRT?
IGRT is one of the most accurate radiation methods available, often achieving sub-millimeter precision. This helps in protecting healthy tissues while delivering high doses to the tumor. - Can IGRT be combined with other treatments?
Yes. IGRT is often used alongside surgery, chemotherapy, targeted therapy, or immunotherapy as part of a comprehensive cancer treatment plan. - Is IGRT available in all hospitals in India?
No. IGRT requires specialized equipment and trained radiation oncologists, so it is mainly available in advanced cancer centers and tertiary care hospitals in major cities.
