Navigated Brain Stimulation (NBS) is used to precisely map the areas controlling muscle movements/activity in the brain. NBS provides advanced patient care while avoiding invasive testing in an operating room. Historically, the only way to duplicate these detailed maps was through a craniotomy. Today, these detailed mappings can be done with Nexstim’s NBS System 5 is a comfortable setting for the patient, prior to surgery.
An NBS session creates an accurate map of the critical functions of the cortex using a standard MRI brain scan. This is done by using navigated transcranial magnetic stimulation (nTMS), similar to mapping the globe with a GPS. The NBS System 5 provides information that allows the physician to determine which areas of the brain are “good”, and accurately determine functional tissue. The data created through a mapping session, helps to plan and visualize surgical strategies and give additional information to help patient and physician discuss treatment options and outcomes.
In a recent study of 250 consecutive patients, presurgical mapping with NBS enabled a more aggressive surgical strategy in more the 75% of the cases. The same study showed the use of NBS data expanded surgical indication by 14.8%. The paper concluded that the integration of NBS into the surgical workflow crucially improves pre-operative planning, patient counseling, and surgical procedures. Leading to longer progression-free survival rates and better neurological outcomes by expanding the indications and extent of resection. 1
