image-guided surgery
Neurosurgical technique using real-time imaging and navigation systems to enhance surgical precision.
Full Definition
Image-guided surgery, also known as computer-assisted surgery or neuronavigation, is a neurosurgical technique that utilizes preoperative imaging data integrated with real-time intraoperative guidance systems to enhance surgical precision and safety. This technology allows surgeons to track instrument position relative to anatomical structures in real-time, facilitating accurate lesion localization, optimal surgical approaches, and preservation of critical structures. Image-guided surgery is particularly valuable for deep-seated lesions, small targets, and procedures requiring high precision such as stereotactic biopsies and functional neurosurgery.
Usage
Usage note: Often abbreviated as 'IGS' in surgical reports; specify navigation system used when relevant.
