Advanced magnetic resonance imaging (MRI) techniques, such as magnetic resonance spectroscopy, diffusion MRI, and perfusion MRI, allow for a diverse range of multidimensional information regarding brain tumor physiology to be…
Functional magnetic resonance (fMR) imaging and diffusion MR tractography have emerged as valuable tools in the evaluation of verbal language in brain tumor patients, and have changed the way neurosurgeons…
This article describes the rationale, indications, and modality for intraoperative brain mapping for safe and effective surgical removal of tumors located within functional brain areas. Intraoperative mapping refers to a…
Treatment of high-grade primary brain tumors is based on experience from multicenter trials. However, the prognosis has changed little in 3 decades. This suggests that there is a fundamental oversight…
Recent evidence suggests that vascular permeability and the presence of vascular endothelial growth factor/vascular permeability factor (VEGF/VPF) are important mediators of brain tumor growth in addition to angiogenesis. Perfusion and…
Transcranial B-mode sonography (TCS) may provide supplementary information to other neuroimaging methods, adding valuable information to the diagnosis and differential diagnosis of movement disorders. The value of TCS in the…
The role for neuroimaging in the management of patients with tremor is gradually increasing, particularly with respect to stereotactic neurosurgery and deep brain stimulation where less than 2-mm tolerance is…
The main role of computed axial tomography in the field of movement disorders was to exclude uncommon but potentially reversible structural abnormalities including tumors, chronic subdural hematoma, and communicating hydrocephalus…
The substantia nigra and subthalamic nucleus are two key structures in the midbrain that are very important in movement disorders, particularly those associated with parkinsonism. Using conventional magnetic resonance (MR)…
Functional neurosurgery involves precise surgical targeting of anatomic structures to modulate neurologic function. From its conception, advances in the surgical treatment of movement disorders have been intertwined with developments in…
