Abstract
Interactive, image‐guided, stereotactic neurosurgery systems and advanced computer programs enable neurosurgery teams to use magnetic resonance imaging (MRI) and computed tomography (CT) scans to perform less‐invasive intracranial tumor excisions. This new methodology, also known as frameless stereotactic neurosurgery, provides accurate, precise preoperative and intraoperative patient information to neurosurgeons. Neurosurgeons use a pointing device to communicate surgical locations quickly to a computer system. The computer then provides immediate, three‐dimensional displays of pertinent MRI and CT scan information on the monitor. These intracranial images serve as navigational guides to neurosurgeons before and during surgical intervention. Interactive, image‐guided, stereotactic neurosurgery systems, however, are only surgical tools, not substitutes for health care providers' knowledge or expertise. Neurosurgeons must balance their medical judgment with interpretations of computer‐generated information throughout the surgical procedures. Interactive, image‐guided systems should not interfere with patient care priorities but rather should be worked into the intraoperative nursing routine. AORN J 61 (Feb 1995) 360–370.
