In neurosurgery and ear, nose and throat surgery the application of computerised navigation systems for guiding operations has been expanding rapidly. However, suitable models to train surgeons in using navigation systems are not yet available. We have developed a technique using an industrial, rapid prototyping process from which accurate spatial models of the cranium, its contents and patholo...
The authors report on a patient harbouring an unruptured cortical arteriovenous malformation (AVM), who had presented with obstructive hydrocephalus due to compression of the cerebral aqueduct by a large venous varix. A ventriculoperitoneal (VP) shunt was inserted in emergency. Due to its large volume, the AVM was not referred for treatment and a follow-up policy was chosen. After the second VP...
Blood-Oxygenation-Level-Dependent functional Magnetic-Resonance-Imaging (BOLD fMRI) and Diffusion Tensor Imaging (DTI) are specialized MRI-techniques for imaging of eloquent cortices and neural tracts in gray and white matter, respectively. By processing of the BOLD fMRI images, it is possible to map eloquent cortices and visualize them as statistical parametric color coded maps to be overlain ...
