Frameless Stereotactic Radiosurgery for Brain & Spine Tumors

A Bloodless, Non-invasive, Outpatient Treatment for Brain and Spine Tumors

What is Stereotatic Radiosurgery?

 

Stereotatic Radiosurgery (SRS) is a highly targeted and focused radiation treatment which delivers extremely high doses of radiation directly to the target to destroy it.

 

The term stereotactic is a term used in Neurosurgery to refer to the ability to accurately identify a point in 3-dimensional space. Radiosurgery uses technology used in neurosurgery to destroy the tumour. For more technical details, please see here.

Understanding the difference between Surgery and Radiosurgery

Surgery involves physically cutting through tissue and bone to reach the tumor so as to remove it from the body.

Radiosurgery does not involve any cutting at all. The name was given because after destroying the tumor with high doses of focused radiation, the body automatically removes the dead cells, and the cure rate is as if surgery was done

- before SRS

Complete response 3 months after SRS

Spine Metastasis

Spine Metastasis strangulating the spinal cord and compressing the surrounding thecal sac. 

6 months after SRS, tumor has shrunk and the the spinal cord is no longer compressed. Patient no longer has pain and weakness

It is completely painless, bloodless and is done as an outpatient procedure.

Patient does not need to undergo open surgery and does not suffer from operation risks
