The Importance of Functional Mri (fmri) in the Neurosurgical Strategy in Brain Tumors
نویسنده
چکیده
Functional MRI (fMRI) is an indirect depiction of the functionality of brain neurons using local changes of circulation. The continuous evolution of MRI led to pulse sequences which could display the circulation of the brain at rest, with or without exogenous contrast agents. fMRI seems capable of determining the dominant hemisphere and the language centers. This is important for the pre-operational evaluation of patients with lesions in the frontal or temporal lobes (tumors or epilepsy resistive to medication), which might have extended centers in these lobes.

Background and Aim: The methods for detecting brain activation with fMRI, MRI provides a way to measure the anatomical connections which enable lightning-fast communication among neurons that specialize in different kinds of brain functions. Diffusion tensor imaging is able to measure the direction of bundles of the axonal fibers which are all aligned. Besides mapping white matter fiber tracts,...

The Intraoperative MRI is of great importance in the surgical removal of gliomas or cranial base tumors. However, the sole use of a intraoperative MRI is problematic, so that a dual system has been developed to optimize the utilization of the equipment, which can be used both for neurosurgical patients and for outpatient or stationary Patients. Within the framework of the new head Center at the...

Objective(s): Systemic lupus erythematosus (SLE) is an autoimmune disease with a wide range of clinical manifestations. Cognitive dysfunction is one of the manifestations that could present prior to the emergence of any other neuropsychiatric involvements in SLE. Cognitive dysfunction is a subtle condition occurring with ahigh frequency. However, there is no data on the correlation of cognitive...
متن کاملUsing functional magnetic resonance imaging (fMRI) to explore brain function: cortical representations of language critical areas
Pre-operative determination of the dominant hemisphere for speech and speech associated sensory and motor regions has been of great interest for the neurological surgeons. This dilemma has been of at most importance, but difficult to achieve, requiring either invasive (Wada test) or non-invasive methods (Brain Mapping). In the present study we have employed functional Magnetic Resonance Imaging...
