Accuracy and outcomes of diffusion tensor imaging tractography in resection for vestibular schwannoma for facial nerve preservation
2021, Journal of the Neurological SciencesCitation Excerpt :Preoperative surgical planning with proper imaging of the tumor adjacent to the FN may contribute to better patient outcomes [18,39]. In the past, imaging modalities were limited in their ability to accurately image the displaced FN [19,40,41]. This is due to the tumor mass effect that splays the FN and the lack of cerebrospinal fluid between the two structures [42].
Imaging and Epilepsy: The Key to Surgical Success
2015, Image-Guided NeurosurgeryApplication of magnetic resonance tractography in the perioperative planning of patients with eloquent region intra-axial brain lesions
2011, Journal of Clinical NeuroscienceCitation Excerpt :Hence, their resection requires a detailed understanding of their functional and anatomical relationships to formulate a surgical plan. Diagnostic modalities currently used to define eloquent regions – standard MRI scans, positron emission tomography, magnetoencephalography and functional MRI scans – demarcate important functional areas of the cerebral cortex but do not delineate the subcortical white matter.1,2 Parallel axon bundles with structured myelin lamination permit preferential diffusion of water molecules along the direction of the fiber tracts.
Functional Magnetic Resonance Imaging
2010, Seminars in RoentgenologyCitation Excerpt :By using optimized and standardized protocols, fMRI examinations can be integrated into routine MRI imaging. There is an established role of fMRI in preoperative mapping of eloquent brain cortex adjacent to potentially resectable pathologies, such as tumors or epileptogenic foci.14-18 The goal of oncological surgical treatment is the complete removal of the abnormality, while minimizing the risk of inducing permanent neurological deficits.
