Method for recording and evaluating PET data recorded at the same time as magnetic resonance data using a combined magnetic resonance/PET apparatus, and a combined magnetic resonance/PET apparatus

A method for recording and evaluating Positron Emission Tomography (PET) data recorded at the same time as magnetic resonance data using a combined magnetic resonance/PET apparatus, wherein in the context of a pulse sequence for recording the magnetic resonance data, a magnetic resonance recording device, including at least one gradient coil and at least one high-frequency coil, is activated, the method comprising:

• recording the PET data and assigning at least a first portion of the recorded PET data after the recording time point to at least two data groups assigned to an operating state of the magnetic resonance recording device;
• determining, for each of the at least two data groups, a measure of similarity of the PET data contained therein to at least one of the PET data and at least one further data group including a second portion of the PET data;
• and
• at least one of rejecting and further separately evaluating the PET data of each of the at least two data groups if the determined measure of similarity is below a threshold value.
