1. A method for analyzing diagnostic image data, the method comprising:
obtaining a first diagnostic image of a vessel of interest in a patient's vasculature and a second diagnostic image of the vessel of interest in the patient's vasculature, wherein a first visual appearance of the vessel of interest in the first diagnostic image and a second visual appearance of the vessel of interest in the second diagnostic image are different from one another such that one or more vessel positions are represented differently in the first diagnostic image and the second diagnostic image,
defining at least one determination position for the vessel of interest in the first diagnostic image and at least one corresponding determination position for the vessel of interest in the second diagnostic image,
determining a first value for at least one functional parameter at the at least one determination position in the first diagnostic image and a second value for the at least one functional parameter at the at least one corresponding determination position in the second diagnostic image, and
determining a correlation between the first visual appearance of the vessel of interest and the different, second visual appearance of the vessel of interest based on comparing the first value of the at least one functional parameter at the at least one determination position and the second value of the at least one functional parameter at the at least one corresponding determination position, wherein the correlation is between the one or more vessel positions as represented in the first diagnostic image with the one or more vessel positions as represented in the second diagnostic image.
