Abstract:
1. A method for determining an arterial input function from a magnetic resonance image dataset, the method comprising: providing a user interface configured to display at least one magnetic resonance image from the magnetic resonance image dataset and a plurality of time-course graphs simultaneously, the plurality of time-course graphs associated with a selected region of the at least one magnetic resonance image and each time-course graph having associated time-course data; automatically annotating, using a processor, at least one displayed time-course graph with at least one element that highlights one or more portions of the at least one displayed time-course graph indicating fitness of the time-course data associated with the at least one time-course graph for use in deriving an arterial input function, wherein the at least one element is a shaded area of the at least one displayed time-course graph that indicates the fitness of the time-course data; receiving a selection of a time-course graph from the plurality of time-course graphs; and deriving an arterial input function from the time-course data associated with the selected time-course graph.
