    摘要: In a magnetic resonance method and apparatus to measure a sodium content in tissue in a first slice, a determination of a blood volume in blood vessels in the first slice is made, and an MR acquisition sequence to acquire MR data of a sodium-23 magnetization from the first slice is implemented. A signal proportion of the MR data that originates from the sodium-23 magnetization in blood vessels is calculated based on the determined blood volume in tissue. This signal proportion is subtracted from a total signal of the MR data to obtain a corrected signal that is proportional to the sodium content in tissue. The sodium content in tissue is calculated from the corrected signal.

The unit part of the PRT includes at least two gamma ray detector units with in each case an assigned electronics unit. The MRT includes a second evaluation unit, a gradient coil system and a high frequency antenna device formed as a stripline antenna device having at least two conductors. The high frequency antenna device is arranged nearer to the examination space than the gradient coil system with a high frequency shield between the gradient coil system and the high frequency antenna device. Each conductor of the stripline antenna device respectively includes a gamma ray detector unit with an assigned electronics unit. The conductors of the stripline antenna device are configured for the respective gamma ray detector units and their assigned electronics units as shielding covers that are caused by the high frequency antenna device and are opaque to high frequency radiation.

    摘要: A method for determining positron emission measurement information in the context of positron emission tomography is disclosed. The method includes using a marker substance to carry out a positron emission measurement, in a body area of a subject to be examined, to determine positron emission measurement information, and at the same time, generating images of the body area to be examined by way of a second medical method with a time resolution suitable for determining perfusion and/or diffusion information. The method further includes using the images from the second method to determine perfusion and/or diffusion information for at least a part of the measurement period, and evaluating the positron emission measurement information as a function of the perfusion and/or diffusion information.

    摘要: A method is disclosed for determining positron emission measurement information in the context of positron emission tomography. The method includes carrying out a positron emission measurement, in a body area of a subject to be examined, to record positron emission measurement information with point resolution and determining a time frame of the measurement by, at the same time, generating images of the body area to be examined with a relatively higher time resolution and with point-resolved image data, using a second imaging method. Further, a local shift of points of individual images of the second imaging method is determined, caused by movement processes of the subject to be examined, and as a function thereof, of the positron emission measurement information for at least a part of the measurement period and of the body area to be examined. Finally, the positron emission measurement information is adjusted as a function of the determined shift.
