Advanced imaging technique now developed to enable Neurosurgeons
with intra-operative MRI to aid in the removal of complex and hard-to-access
brain tumors during surgery. This new technique relies on a powerful computer
system, which assists the surgeon in precisely localizing a lesion, in
planning each step of the procedure on the computer screen, and in
calculating the ideal access to the tumour before the operation.
This is particularly useful in reaching a tumour located deep
inside the brain, areas traditionally considered to be difficult to reach.
During the procedure, the computer tracks instrument movement with an
extremely high precision, providing the surgeon with total control inside the
brain at all times using "real-time" imaging. The surgeon can also
check if the tumor has been removed as planned. This improves the outlook for
the patient.
At Our world class hospitals in India we have also begun to use
functional image-guidance for patients undergoing stereotactic radiosurgery.
The surgeons are highly qualified for stereotactic
radiosurgery at the Indian
hospitals and give their best for the satisfaction of the patients.
Stereotactic radiosurgery is a highly precise form of radiation therapy used
primarily to treat tumors and other abnormalities of the brain.
There have been considerable differences in cost between the countries like USA, UK, Canada & South Africa
as compared to India when it comes to medical treatment. Gamma knife
radiosurgery involves four phases: placement of the head frame, imaging of
tumor location, computerized dose planning, and radiation delivery. You can
also estimate the cost of some common treatments, which are based on average
treatment cost of various hospitals & clinics. Patient can evaluate the
kind of savings they can do by taking decision of traveling for their
treatments like stereotactic radiosurgery at Indian hospitals
Stereotactic
radiosurgery is a non-surgical procedure that uses highly focused x-rays to
treat certain types of tumors, inoperable lesions and as a post-operative
treatment to eliminate any leftover tumor tissue or to obliterate abnormal
blood vessels in congenital arteriovernous malformations. The treatment
involves the delivery of a single high-dose—or sometimes smaller, multiple
doses—of radiation beams that converge on the specific area of the brain
where the tumor or other abnormality resides.
Using a helmet-like device that
keeps the head completely still and three-dimensional computer-aided planning
software, stereotactic radiosurgery minimizes the amount of radiation to
healthy brain tissue. It is an important alternative to invasive surgery,
especially for tumors and blood vessel abnormalities located deep within or
close to vital areas of the brain.
Radiosurgery is used to
treat many types of brain tumors, both benign or malignant and primary or
metastatic. Additionally, radiosurgery is used to treat arteriovenous
malformations (AVMs), a tangle of expanded blood vessels that disrupts normal
blood flow in the brain and is the leading cause of stroke in young people.
Although stereotactic radiosurgery is often completed in a one-day session,
physicians sometimes recommend a fractionated treatment, in which treatments
are given over a period of days or weeks. This is referred to as stereotactic
radiotherapy. It works in the same way as other forms of radiation treatment.
It does not actually remove the tumor; rather, it distorts the DNA of tumor
cells. As a result, these cells lose their ability to reproduce.
Following
the treatment, benign tumors usually shrink over a period of 18 months to two
years. Malignant and metastatic tumors may shrink more rapidly, even within a
couple of months. When treated with radiosurgery, arteriovenous malformations
(AVMs) begin to thicken and close off.
