Intraoperative magnetic resonance imaging in neurosurgery.
Intraoperatively magnetic resonance (MR)-guided neurosurgical operations have been done since 1996, mostly for brain tumors. Several different concepts for intraoperative MRI procedures using low-, middle-, and high-field MR scanners have been reported from pioneering neurosurgical centers. In this article, we present the different solutions used in these centers from a practical point of view....
متن کاملIntraoperative ultrasound-guidance in neurosurgery.
ince the first recorded use of the “ultrasonoscope” for localizing subcortical intracerebral neoplasms in postmorS tem specimens in 1950 (4), technological advances in ultrasound have seen a transformation from poor-quality, A-mode wave forms to superb-quality, real-time images in 2 (2D) and 3 (3D) dimensions. As a result, intraoperative ultrasonography (IOUS) has undergone remarkable developme...
متن کاملIntraoperative magnetic resonance imaging in pediatric neurosurgery: safety and utility.
OBJECTIVE The use of high-field intraoperative MRI has been largely studied for the treatment of intracranial tumors in adult patients. In this study, the authors investigated the safety, advantages, and limitations of high-field iMRI for cranial neurosurgical procedures in pediatric patients, with particular attention to craniopharyngiomas and gliomas. METHODS The authors performed 82 surgical...
متن کاملRetrospective study comparing model-based deformation correction to intraoperative magnetic resonance imaging for image-guided neurosurgery.
Brain shift during tumor resection compromises the spatial validity of registered preoperative imaging data that is critical to image-guided procedures. One current clinical solution to mitigate the effects is to reimage using intraoperative magnetic resonance (iMR) imaging. Although iMR has demonstrated benefits in accounting for preoperative-to-intraoperative tissue changes, its cost and encu...
