    摘要： A computerized method is disclosed for detecting a brain region with neurodegenerative change and also a brain region with vascular change in the brain of a patient and also an imaging arrangement suitable for this. In at least one embodiment, the method includes recording a first data record of the brain via positron emission tomography and a second data record of the brain via magnetic resonance imaging; reconstructing a PET image from the first data record and an MRI image from the second data record; identifying evidence for a brain region with vascular change in the MRI image; segmenting the MRI image into gray matter and white matter; identifying a brain region with neurodegenerative change in the PET image; and superposing the PET image and the segmented MRI image to determine whether the brain region with neurodegenerative change is present in gray matter or in white matter, the recording of the first data record and the second data record being carried out in quick succession without repositioning the patient or is even carried out simultaneously.

    摘要： A computer-implemented method is disclosed for determining and displaying an access corridor to a target area in the brain of a patient, as well as an imaging arrangement suited to this. In at least one embodiment, the method includes a) generating a first image of the brain via positron emission tomography, b) discriminating the target area relative to its surroundings via electronic image processing, c) generating a second image of the brain via magnetic resonance imaging while acquiring at least one anatomical structure, d) generating a third image of the brain via an imaging method displaying physiological processes for identifying at least one functional area of the brain that must not be injured in any circumstances, e) determining an access corridor to the target area while omitting the at least one functional area of the brain, and f) generating and displaying a fourth image of the brain in which the target area, the at least one functional area of the brain, the at least one anatomical structure and the access corridor are displayed, wherein steps a) to d) are carried out, one after another in quick succession, in a single frame of reference without repositioning the patient, or are even carried out simultaneously.

In order to allow improved relative positional determination of the epileptogenic focus with reference to the EEG electrodes, a positron emission tomography measurement using at least one radiation detector, and a magnetic resonance imaging measurement using at least one coil for generating a basic magnetic field, at least one gradient coil and a radio-frequency antenna device are undertaken in at least one embodiment. In addition, in at least one embodiment an electroencephalography measurement using a plurality of electrodes for acquiring spatial and temporal changes of the electrical activities of the brain and a computed tomography measurement using at least one x-ray source and at least one x-ray detector are carried out. By way of an evaluation apparatus in at least one embodiment, a spatial correlation between the computed tomography measurement and the magnetic resonance imaging measurement is undertaken, so as to result in registration between the electroencephalography measurement and the positron emission tomography measurement.
