Objective: Tractography based on diffusion weighted (DW)-images has been progressed in order to optimize reconstruction results. However, in studies on tractography based on diffusion tensor imaging (DTI), parameters of DW-imaging schemes differ regarding for example gradient directions, b-value or [for full text, please go to the a.m. URL], 65.

Objective: As maximization of extent of resection with minimized postoperative deficits, especially in case of primary brain tumors, is correlated with improved outcome, precise and reliable information about location and spatial extent of white matter tracts is indispensable. In this way, Diffusion[for full text, please go to the a.m. URL], 65. Jahrestagung der Deutschen Gesellschaft für Neurochirurgie (DGNC)

Objective: Diffusion Tensor Imaging (DTI) and fiber tractography became popular and widespreadly used methods to visualize major white matter tracts in the human brain in-vivo. In case of glioma surgery, precise and reliable information about spatial localization and course of fiber bundles is essential[for full text, please go to the a.m. URL], 64.

Objective: Diffusion tensor imaging (DTI) based fiber tractography has proven its impact in neurosurgical practice with low postoperative morbidity. However, there is a major drawback for the spatial locations of crossing-, kissing-, or fanning fibers and in the vicinity of tumor or edema. The diffusion[for full text, please go to the a.m. URL], 63.

Objective: Ventricular catheterization with external ventricular drainage (EVD) is a commonly used neurosurgical procedure for treatment of acute cerebrospinal fluid circulation disturbances. The most frequent reasons for EVD application are intracranial or subarachnoidal hemorrhages, pre-surgical treatment[for full text, please go to the a.m. URL], 63.

Objective: In pediatrics, ultrasound allows for sufficient visualization of intracerebral hemorrhage (ICH). Due to the cranium, in adulthood ultrasound images contain multiple artefacts so that the diagnosis of ICH is hindered. This is based on scattering and attentuation of the ultrasound.

Objective: Intraoperative imaging and multimodal navigation improved glioma surgery in the last decades. Functional data, integrated in the neuronavigation procedure, has contributed to safe tumor resection for lesions located near eloquent brain structures.

Objective: Microsurgical resection of pineal region lesions remains a challenging topic because of deeply located veins and eloquent mesencephalic structures. The purpose of this study was to analyze this specific approach for the microsurgical resection of pineal region lesions in our consecutively[for full text, please go to the a.m. URL], 61.
