| 1. A method for determining positron emission measurement information in the context of positron emission tomography, comprising:
using a marker substance to carry out a positron emission measurement during a measurement time period, in a body area of
a subject to be examined, to determine positron emission measurement information;
scanning the body area to be examined during at least a part of the same measurement time period to obtain data sets with
a time resolution suitable for determining at least one of perfusion and diffusion information;
generating images based on the data sets obtained during the scanning using a second method;
using the generated images from the second method to determine the at least one of perfusion and diffusion information for
at least the part of the measurement time period; and
evaluating the positron emission measurement information as a function of the at least one of perfusion and diffusion information.
