摘要： A method for determining a change over time in a biomarker in a region to be examined of a patient is provided. The change is determined from magnetic resonance data using a magnetic resonance measuring system with sequences and protocols for measuring the biomarkers by functional resting state connectivity by rsfMRI, perfusion values, magnetic resonance spectra of voxels, or morphometry of organs. A control unit has programs which evaluates the biomarker and a data memory which stores the results of the evaluation and additional data. During a first examination, a quantity result of the biomarkers is determined and stored in the data memory. During a follow-up examination, at least one previous item of the result and additional data from the first examination stored in the data memory are used for determining a quantitative change in the biomarker.

摘要： A method and a device for imaging a volume section by way of PET data are described. With the proposed solution the PET data of the volume section are acquired by way of a positron emission detector, and the MR data of the volume section are acquired by way of a magnetic resonance system. In at least one embodiment, with the aid of the MR data, PET voxels within the volume section are determined from which radiation occurring due to an annihilation is emitted. The image data are reconstructed from the PET data in that it is taken into account that the PET data are generated only by radiation from the PET voxels.

摘要： In a method to measure characteristic structure sizes of the human brain, which structure sizes can be used as biomarkers for a diagnosis of Alzheimer's, using a magnetic resonance device, manual and/or automatic localization of the hippocampus takes place in a preliminary magnetic resonance acquisition, followed by selection of at least one measurement axis that proceeds through the hippocampus. For each selected measurement axis, magnetic resonance data are acquired for a longitudinal, in particular rod-shaped, acquisition region proceeding along the measurement axis. Determination of the spatially resolved structure sizes is implemented from the magnetic resonance data.
