neuronavigation
Computer-assisted surgical guidance system using preoperative imaging to provide real-time spatial orientation during brain surgery.
Full Definition
A sophisticated image-guided surgery system that utilizes preoperative MRI or CT scans to create a three-dimensional map of the patient's brain, allowing surgeons to navigate with millimeter precision during procedures. The system tracks the position of surgical instruments in real-time relative to the patient's anatomy, displayed on computer monitors in the operating room. Neuronavigation has revolutionized neurosurgery by improving the accuracy of tumor localization, reducing the size of craniotomies, minimizing damage to normal brain tissue, and enhancing the safety of procedures in eloquent brain areas. The technology is particularly valuable for accessing deep-seated lesions and planning optimal surgical approaches.
