Intensity Modulated Radiotherapy (IMRT)

What is Intensity Modulated Radiotherapy (IMRT)?

Intensity Modulated Radiotherapy (IMRT) is an advanced form of radiation therapy used to treat cancer with precision and safety. Unlike conventional radiotherapy, IMRT allows radiation beams to conform to the exact shape of the tumor, delivering higher doses to cancerous tissue while sparing surrounding healthy organs. This precision minimizes side effects and improves treatment outcomes.

How IMRT Works?

IMRT uses computer-controlled linear accelerators to deliver precise radiation doses. Sophisticated imaging techniques, including CT, MRI, or PET scans, map the tumor in three dimensions. The radiation intensity can be modulated within each beam, allowing the oncologist to target irregularly shaped tumors while protecting nearby critical structures such as the spinal cord, heart, or kidneys.

Advantages of IMRT

Precision Targeting: Delivers high-dose radiation directly to the tumor.
Reduced Side Effects: Protects healthy tissues surrounding the tumor.
Treatment for Complex Tumors: Effective for tumors located near sensitive organs.
Better Outcomes: Allows for higher doses to the tumor, improving the chance of local control.

Who Can Benefit from IMRT?

IMRT is commonly used to treat cancers including:

Head and neck cancers
Prostate cancer
Breast cancer
Brain tumors
Gastrointestinal cancers
Thoracic cancers

Treatment Process

Consultation: Your oncologist evaluates your condition and recommends IMRT if appropriate.
Planning: Advanced imaging is performed to map the tumor and surrounding tissues.
Simulation: A treatment plan is created using computer software to optimize dose distribution.
Delivery: Radiation is administered over multiple sessions, typically 5 days a week, tailored to your personalized plan.
Follow-up: Regular monitoring ensures the effectiveness of treatment and manages any side effects.

Frequently asked Questions

The department manages the full spectrum of gastrointestinal, hepatic, pancreatic and biliary conditions. This includes acid reflux disease, peptic ulcers, inflammatory bowel disease (Crohn’s disease and ulcerative colitis), irritable bowel syndrome, liver diseases, pancreatitis, gastrointestinal bleeding, gastrointestinal cancers and all conditions requiring diagnostic or therapeutic endoscopy.

Capsule endoscopy involves swallowing a small, vitamin sized capsule containing a tiny camera. As it passes through the digestive tract, it captures thousands of images of the small bowel, an area that is difficult to reach with conventional endoscopy. It is used to evaluate conditions such as obscure gastrointestinal bleeding, Crohn’s disease and small bowel tumours.

Most endoscopic procedures are performed under conscious sedation or short general anaesthesia, so patients typically experience minimal discomfort. The gastroenterology team at Mar Sleeva Medicity Palai ensures patient comfort and safety with ICU level monitoring during and after the procedure.
