Patent ID: 8208987

Claim:
A method for quantifying uptake of at least one radiotracer in a body region of a patient of interest to a positron emission tomography measurement, the method comprising: quantifying the uptake of the at least one radiotracer in the body region of the patient of interest to the positron emission tomography measurement by taking into account at least one permeability information item relating to permeability of at least one blood vessel of the patient determined within the scope of a dynamic contrast-enhanced magnetic resonance imaging measurement, and by taking into account differing permeability of an used contrast agent for magnetic resonance imaging and at least one of the permeability of the at least one radiotracer and relaxivity of the contrast agent, wherein the quantifying occurs based on data relating to the transfer of the at least one radiotracer from the at least one blood vessel of the patient into tissue surrounding the body region.
