IGRT

What is IGRT?

IGRT radiation therapy combines real-time imaging with radiation delivery. This means doctors can see the exact location of the tumour each day, making adjustments when needed for safety and effectiveness.

In simple terms, IGRT ensures radiation reaches exactly where it is meant to go, improving accuracy and protecting healthy tissues.

Why is the IGRT Procedure Needed?

Tumours can shift slightly from day to day due to breathing, digestion, or body movement. IGRT helps correct for these changes so radiation remains accurate. This reduces the risk of side effects and improves treatment results.

Common Reasons and Key Conditions Treated

• We treat cancers that are located close to vital organs or sensitive tissues.
• Cancers in the head and neck necessitate precise targeting.
• Prostate cancers are affected by natural internal movement.
• Lung or abdominal tumours influenced by breathing motion.
• Repeated radiation treatments require enhanced accuracy.

Types of IGRT / Procedure Variations

IGRT uses several imaging approaches to support accuracy. These variations ensure that each radiation session aligns exactly with the treatment plan.

• CT-guided IGRT: Uses specialised CT scans to confirm tumour position.
• Cone-beam CT IGRT: Provides 3D images for detailed alignment.
• X-ray/fluoroscopic IGRT: Helps track tumours that move during breathing.
• Ultrasound-guided IGRT: Often used for prostate positioning.
• Marker-based IGRT technique: Uses implanted markers to guide radiation precisely.

Indications for IGRT

IGRT may be recommended when:

• The tumour moves or changes position day to day.
• A high-dose radiation plan needs maximum accuracy.
• The tumour lies close to nerves, organs, or sensitive tissues.
• Repeated radiation is required for a previously treated area.
• Patients require a treatment approach with strong safety and precision benefits.

Who Should Avoid or Delay IGRT?

Some situations may require alternative treatment planning.

• Uncontrolled medical conditions needing stabilisation first.
• Patients unable to lie still during imaging or treatment.
• Very young children needing sedation without available support services.
• Cases where imaging cannot be performed safely due to medical limitations.

Preparing for IGRT

• Initial imaging, such as MRI or CT scans for detailed mapping.
• Creation of custom masks or moulds to ensure stillness and comfort.
• Discussion about session duration, expected sensations, and schedule.
• Review of medications and general health.
• Planning support for travel and accommodation for international patients.

What Happens During the IGRT Procedure?

An IGRT treatment session usually takes place in a radiation therapy suite. Patients lie comfortably on a treatment table while imaging tools capture the tumour’s position. If any shift is detected, the system adjusts the plan before radiation is delivered.

Step-by-Step Breakdown

• Arrival and positioning on the treatment table.
• Imaging using CT, cone-beam CT, X-ray, or ultrasound.
• Comparison of tumour position with the original plan.
• Automatic or manual adjustment for accuracy.
• The system ensures the precise delivery of radiation beams.
• Completion of treatment, with no downtime needed afterwards.

Recovery After IGRT

Most patients continue their normal routine throughout IGRT. Some may feel mild fatigue, skin sensitivity, or temporary discomfort depending on the treatment area. These effects are usually manageable and improve as treatment progresses.

Regular follow-up helps monitor tumour response and address any long-term changes early.

Risks & Complications

IGRT is designed to minimise risks by improving accuracy. Temporary side effects may include skin redness, fatigue, swallowing discomfort, or digestive changes, depending on the treatment site. Serious complications are uncommon with proper planning.

Benefits of IGRT

• Improved accuracy with daily imaging checks.
• Reduced dose to healthy tissues and organs.
• Better outcomes for tumours that move naturally.
• Supports higher radiation doses when needed.
• Helps protect vital functions while treating cancer effectively.
