University of Pittsburgh Medical Center's center for image-guided neurosurgery completed its 16,000th gamma knife treatment.
Three things to know:
1. The gamma knife treats patients with benign or malignant tumors, vascular malformations, pain and other functional brain conditions.
2. The treatment is non-invasive, bloodless and computer-driven. It uses stereotactic radiosurgery to target specific areas and leave the surrounding tissue intact.
3. UPMC features six gamma knifes and acts as a training center for the device.
