Gamma-ray irradiation concentrates in the target determined by a radiologist. The rays affect diseased cells and stop their growth. Gamma Knife is harmless for healthy cells and surrounding tissues.
What is the difference between Gamma Knife and other methods?
Incisions are not necessary for Gamma Knife session. There is no risk of bleeding, infections or damage to healthy tissues.
Full therapeutic effect is achieved after 1 procedure. When other types if radiosurgery (CyberKnife, Novalis linear accelerator) are applied, a patient receives 5-15 treatment cycles.
The accuracy of ray influence is up to 0.3 mm.
The treatment does not require hospitalization and rehabilitation period. A patient can return to usual lifestyle right after the irradiation.
Preparation for Gamma Knife procedure
A doctor detects tumor size and location using CT or MRI. In case of vascular brain malformations, specialists conduct angiography.
Before irradiation, a radiologist develops a treatment plan using MRI and angiography data. This plan is sent to Gamma Knife unit console.
The Gamma Knife radiosurgery cost is calculated after the complete diagnostics.
Gamma Knife procedure process
A patient is placed on the table. A doctor fixes the head in the special stereotactic frame. Soft sedatives are injected so a patient feels comfortable.
The apparatus directs the irradiation inside the tumor. It detects tumor size according to the treatment plan and coordinates frame.
The treatment takes from 10 minutes to several hours. The duration depends on the number of targets, their shape, and size. It also affects the Gamma Knife treatment cost.
During therapy, a doctor controls and communicates with a patient through video/audio monitoring.
After irradiation
When the procedure is over, a patient can return to usual lifestyle. The effect is not immediate, so a patient needs to undergo regular MRI. This way a doctor observes Gamma Knife therapy efficiency.
