Understanding Advanced Radiation Therapy Techniques: From IMRT to Stereotactic Radiosurgery

In the constantly changing field of cancer treatment, the difference between a great result and unnecessary side effects is often just a few millimetres. Precision is the foundation of today’s cancer treatment, and if you are among those who want to get treatment from the best in the world, consulting a Leading Radiation Expert in Yashoda Medicity means you will have access to the best medical technology.

Advanced radiation therapy has undergone the transition from a more general method to an exact weapon, thus doctors can kill cancer cells and at the same time, keep the healthy tissues outside the radiation field alive. Now, with the help of an experienced Radiation Oncologist in Delhi NCR, patients can face complex medical problems with less anxiety and thus have an overall immense improvement in the quality of their lives. 

The Evolution of Precision: Why Advanced Radiotherapy Matters

Earlier, conventional radiotherapy was hardly more than a floodlight blinding the tumour, but it also compromised the surrounding healthy anatomy. With the new techniques, it is more like a sniper’s rifle pointing directly at the target. As knowledge of tumour biology expands, a uniform, one-size-fits-all approach is out of fashion, and precision medicine becomes the norm. With IMRT and SBRT, there is a possibility of dose escalation to very high levels, which means the tumour will receive more radiation. 

However, the risk to organs at risk will not increase with these techniques. This transition is particularly important for tumours near delicate tissues, such as the brain, spine, or lungs.

What is Intensity-Modulated Radiation Therapy (IMRT)?

IMRT, by definition, is a high-accuracy radiotherapy that utilises computer-controlled linear accelerators to deliver very precise doses of radiation to a cancerous tumour or specific parts of the tumour.

The basic idea behind this is that the radiation beam is divided into thousands of very small “beamlets.”

• The strength of each beamlet can be adjusted, allowing the dose to be “moulded” and fitted very closely to the 3D shape of the tumour.
• Benefits: If a tumour has an odd shape or is closely wrapped around healthy organs, as in head-and-neck and prostate cancers, this can be a lifesaver.

IGRT: Enhancing Accuracy Through Real-Time Imaging

Image-guided radiation therapy (IGRT) is a technique that uses repeated imaging (CT, MRI, or PET) throughout the treatment.

The Problem: Tumours can move around between treatment sessions or even during a single session because of breathing or organ filling (for example, the bladder).

The Solution: IGRT enables the oncologist to pinpoint the tumour just before radiation is delivered, adjusting the patient’s position in real time so the beam hits the tumour accurately every time.

The Expertise Behind the Technology: Dr. Gagan Saini

Technology is only as effective as the hands that guide it. Dr. Gagan Saini, a postgraduate from AIIMS New Delhi and a Diplomate of the National Board, brings over 25 years of experience to the field. He is recognised as a top Radiation Oncologist in Delhi NCR and has the expertise to handle any case, thanks to his knowledge of modern care facilities. Some of the latest technologies he uses are:

• Intrafraction Motion Tracking and ExacTrac.
• Biology, Guided (BgRT) and MRI, Guided Radiotherapy (MRgRT).
• Highly targeted therapy, such as Total Skin Electron RT (TSET).

Dr. Saini is internationally acknowledged for his dedication to evidence-based treatment and his remarkable capability to merge the top technology with a warm, patient-centred approach.
