Neuronavigation, also known as computer-assisted brain surgery or image-guided surgery, is a technique that uses advanced imaging technology to help neurosurgeons plan and perform precise and minimally invasive brain surgeries. By using preoperative imaging scans such as MRI or CT, neuronavigation systems create a detailed, three-dimensional map of the patient's brain. This map is then used during surgery to guide the surgeon's instruments in real-time, providing a high level of accuracy and safety.

Neuronavigation allows neurosurgeons to navigate through the brain with greater precision, avoiding critical structures and minimizing damage to healthy tissue. It is particularly useful for complex surgeries such as tumor resection, epilepsy surgery, and deep brain stimulation. This technology also helps surgeons plan the best surgical approach, make smaller incisions, and complete surgeries more efficiently.

By increasing the accuracy of brain surgeries and improving patient outcomes, neuronavigation has become a valuable tool in modern neurosurgery. However, it requires skilled operators and is often used in conjunction with other advanced technologies such as intraoperative imaging to ensure the best possible surgical results.
