Abstract
A method of evaluating changes in contrast of an image using a diagnostic imaging system is provided. The method provides acquiring raw image data of an organ or tissue, calculating a baseline of data based on the raw image data acquired before arrival of an agent, and determining changes in a signal intensity of the agent based on changes in the raw image data compared to the baseline. The agent may be an imaging agent, a contrast agent, a biomedical agent, a needle, a catheter, a biomedical device, and the like.
