Claim 0:
1. A method for processing magnetic resonant imaging (MRI) data via a memory and a controller, the memory storing instructions that, when executed by the controller, performs a set of operations comprising:
receiving, at a MM workstation, respective electronic MRI data of an imaged tissue volume acquired by different MRI scanners over respective periods of time after a respective contrast agent is introduced into a patient while at least a portion of the patient is positioned within respective different MM scanners;
converting, by a control processor, a plurality of signal enhancement ratio curves associated with the respective electronic MRI data from the different MRI scanners into an absorption rate curve, the absorption rate curve describing absorption rates of the respective contrast agent in the imaged tissue volume and compensating for a non-linear relationship between an MRI signal generated by an MRI scanner during imaging of the imaged tissue volume and a concentration of the respective contrast agent over time;
wherein the absorption rate curve is determined by deriving a signal intensity ratio for the imaged tissue volume based on an actual absorption rate of the respective contrast agent in the imaged tissue volume for all of the different MM scanners;
normalizing the derived signal intensity ratio for the imaged tissue volume so that a signal enhancement ratio is independent of the MRI scanners used to generate the electronic MRI data; and
displaying, at a display of the MRI workstation, the absorption rate curve of the respective contrast agent in the imaged tissue volume.
