Problems solved by technology

The disadvantage here is both the increased time requirement due to the separate examination and the associated discomfort for the patient, as well as the use of the time interval between the individual modalities.
Because MRI images and PET images are not taken simultaneously, conditions may be different and brain processes cannot be correlated simultaneously

Embodiment Construction

[0036] figure 1 A schematic diagram of the medical examination device 1 according to the invention is shown. The device comprises a combined magnetic resonance-PET system 2 , which includes a cartridge magnet 3 , as well as gradient coils and radio-frequency coils (not shown in detail here), for recording magnetic resonance image data. Inside the magnet 3 is arranged a PET detector 4 for recording PET image data. The magnet 3 and the PET detector 4 define a patient opening into which the patient can be driven on the patient table 5 in order to be able to carry out a brain function test.

[0037] Furthermore, the medical examination device 1 can also comprise other optional components, which can either be constructed in a combined MRI-PET system (with which simultaneous and concentric processing of MRI and PET image data can additionally be carried out). record), or can be provided as an external device. These optional components include: patient cooperation detection means ...

Abstract

A method for data recording and / or data analysis in the brain function test of a combined magnetic resonance-PET apparatus is disclosed, wherein the function image data are recorded through two modes according to at least two active states, the recording of the magnetic resonance image data and the PET image data is performed in the interior of the time window determined by the active states, then recording operation and / or the synchronization of image data are performed according to the exciting time sequence determining the active states.

Description

technical field [0001] The invention relates to a method for data recording and / or data analysis in brain function examinations with a combined MRI-PET (Positron Emission Tomography) apparatus, wherein at least two states of activity are followed by two modalities Record functional image data of the brain. Background technique [0002] In order to observe processes in the brain, it is known to perform examinations by means of functional magnetic resonance imaging and PET imaging. In such examinations, image data are usually recorded alternately from the normal state and during different forms of brain activity (ie, according to different activity states), and the results are compared. In this case, in particular diagnostic magnetic resonance imaging can be performed in addition to functional magnetic resonance imaging. The active centers can then be spatially assigned with the aid of these magnetic resonance recordings. If different states of activity are distinguished, f...
