Pr�operative Bildgebung

Abstract

With the progressive development of soft- and hardware, the acceptance of image-guided neurosurgery has increased dramatically. Additional image data are required to analyze the nature and the dimensions of pathological processes and the surrounding tissue. In this context, fMRI, SPECT, PET, as well as special modalities of CT and MR imaging, are routinely used. Secondary post-processing options are used to detect intracerebral lesions as well as adjacent functional eloquent regions in the parenchymatous organ pre- and intraoperatively. The integration of different image information guarantees the precise planning and realization of surgical maneuvers. The segmentation of interesting structures and risk structures, as well as their implementation in the neuronavigation systems, help to avoid additional intraoperative traumatization and offer a higher level of safety and precision. In this article the value and limitations of presurgical imaging will be discussed.

Intracranial abscesses: Retrospective analysis of 32 patients and review of literature

“…[2,8] With progress in the development of neuronavigational systems, the acceptance of image-guided neurosurgery has increased dramatically refining surgical access, improving accuracy, and reducing the morbidity. [3,[43][44][45][46] Image-guided (CT or MRI) frameless stereotactic aspiration techniques have become valid alternatives to traditional methods, namely, conservative medical treatment, craniotomy, and open surgical excision, especially for small and deep (<2 cm) abscesses. [3,[43][44][45][46] However, craniotomy excision or marsupialization is still performed for as much as 72% of the intracranial abscesses in many centers.…”

[2,3,13,29] To avoid recurrence, attention should be given to the predisposing condition, and as many as 40% may require sinus surgery, stressing multispecialty approach to complete treatment.…”
