General Advantages
Gamma Knife Offers Greater Precision, Less Risk
Compared with other approaches, the Gamma Knife® offers greater precision, lower risk and more comfort and convenience.
More Precise
- Submillimeter accuracy (+/- 0.3mm)
- Treats irregularly shaped tumors well
- Cobalt radiation from 201 individual beams, not wide arcs
- Patient's head is held in a secure, fixed position throughout treatment
- Machinery has no moving parts during treatment that could introduce variability
Lower Risk
- Noninvasive procedure virtually eliminates risk of hemorrhage or infection
- Radiation treats targeted area with little effect on surrounding tissue as little as 1mm away
- No need for general anesthesia
- Few complications
- Allows treatment of patients otherwise considered to be at high risk for surgery
- Allows treatment of otherwise inoperable tumors
Greater Comfort
- Generally a single treatment
- Patients experience little discomfort - and no hair loss or surgical scar
- Short hospitalization time (typically patients leave same or next day)
- Patients can resume normal activities in 24-48 hours
Lower Costs
- Overall costs typically lower than for traditional neurosurgery, which requires intensive care, extended hospital stay and rehabilitation
- Covered by most insurance plans
