Gamma Knife Radiosurgery: No Incision, No Hospital Stay
Mischer Neuroscience Institute acquired the region's first Leksell Gamma Knife® in 1993.
The Memorial Hermann Mischer Neuroscience Institute at the Texas Medical Center acquired the region’s first Leksell Gamma Knife® in 1993, and is now using the more advanced Leksell Gamma Knife® Perfexion™. Neurosurgeons affiliated with the Institute have performed more than 3,500 Gamma Knife procedures.
The Gamma Knife’s fine-beam technology is specifically designed to treat delicate brain tissue. Extra margin or additional volume surrounding the tumor is rarely needed, which spares healthy brain tissue. With the Gamma Knife there are no moving parts during the delivery of radiation, which means that the source of radiation and the target are always in a fixed relationship during treatment, ensuring the highest degree of accuracy. Treatment is typically delivered in a few hours on a single day.
Patients who benefit from the Perfexion’s sophisticated software with dose-to-target conformation include those with meningiomas and vestibular schwannomas; astrocytomas; arteriovenous malformations; medically refractory trigeminal neuralgia; glioblastoma multiforme; and tumors that have metastasized from other areas of the body to the brain.
At the Mischer Neuroscience Institute’s Brain Metastases Clinic, a multidisciplinary team of affiliated neuro-oncologists, neuroradiologists, neuropathologists and neurosurgeons works closely together to provide patients with personalized, evidence-based care. This approach is designed for patient convenience and also allows for quicker and better clinical decision-making by several specialists, who are faculty and researchers at McGovern Medical School at UTHealth.
Patients can expect personalized service from a team that will be with them throughout their treatment. The Institute’s Imaging Review Board, which includes an affiliated radiation oncologist, radiologist and neurosurgeon, meets to review results each time a patient has a new MRI. They also assist patients in arranging any other treatments they may need, including surgery, radiation therapy and chemotherapy.
The Institute’s treatment team closely tracks each patient’s progress and outcomes and tailors treatments accordingly. They also offer those who are eligible the opportunity to participate in new clinical trials as they are available.
