Neurotraumatology: ultrasonic evaluation of the central nervous system

In this study we describe the technique of intraoperative ultrasound imaging of brain and spinal cord in trauma patients. The images are shown and their interpretation is discussed. This intraoperative imaging allows for localization of hematomas, bone fragments and indriven foreign bodies (i.e., pieces of plastic, glass, metal, etc.). Disc material and bone fragments deep to the spinal cord can be localized with this technique. Real-time ultrasound can be used to guide instruments within the brain and, thereby, provide dynamic guidance for removal of bone fragments and foreign bodies dynamically. In summary, intraoperative real-time ultrasonic imaging is of use to the neurosurgeon in the treatment of the neurotrauma patient.
