Which technique is used in Neuronavigation?
This procedure is called image fusion. It can be performed by a neurosurgeon manually by superposing the correspondent images in both sets of images (for example, PET and MRI/CT).
How does Neuronavigation work?
Neuronavigation provides a precise surgical guidance by referencing this coordinate system of the brain with a parallel coordinate system of the three-dimensional image data of the patient that is displayed on the console of the computer-workstation so that the medical images become point-to-point maps of the …
What is stereotactic Neuronavigation?
Stereotactic neuronavigation is an image-guided system that gives the veterinary surgeon real-time intraoperative guidance during operations. Using stereotactic neuronavigation results in more flexibility and control, which are both essential for complicated spinal and brain surgeries.
What are the main surgical management for brain tumor?
Craniotomy. The most common type of surgery to remove a brain tumor is a craniotomy. This procedure involves making an incision in the scalp and removing a piece of bone from the skull to give the neurosurgeon access to the tumor.
Why is Neuronavigation important?
Neuronavigation utilizes preoperative MRI and/or CT to guide the surgery in a 3D anatomical orientation. This is extremely helpful in patients with incomplete or lacking pneumatization of the sphenoid sinus and during reoperations. The recognition of the midline is crucial in transsphenoidal surgery.
How is Tractography done?
In neuroscience, tractography is a 3D modeling technique used to visually represent nerve tracts using data collected by diffusion MRI. It uses special techniques of magnetic resonance imaging (MRI) and computer-based diffusion MRI. The results are presented in two- and three-dimensional images called tractograms.
What is frameless Neuronavigation?
Neuro-Navigation, also termed frameless stereotactic surgery, is the ability to perform real-time intra-operative guidance during brain and/or spinal surgery. This ability increases the accuracy and safety in neurosurgery. Indeed such technology is becoming a standard in neurosurgery.
What is the recovery time after spinal tumor removal?
Typically, patients remain in the hospital for 5 to 10 days after surgery to remove a spinal tumor. Physical rehabilitation is always part of the recovery process. The length of recovery time varies widely, ranging from 3 months to a year.
What is an O arm in surgery?
The O-armTM system is an intraoperative 2D/3D imaging system that is designed to meet the workflow demands of the surgical environment. It can be used in variety of procedures including spine, cranial, and orthopedics.
What is the purpose of tractography?
What is white matter tractography?
WHITE MATTER TRACTOGRAPHY (WMT) White Matter Tractography techniques estimate the connectivity patterns between different brain regions from the continuity in the local estimates of fiber direction at each voxel. To date, a large number of WMT algorithms have been proposed.
