Method and system for monitoring effectiveness of a treatment regimen

A method and system for assessing the effectiveness of a treatment regimen. In a preferred embodiment, baseline magnetic resonance imaging signals of a diseased portion of a subject's anatomy are acquired and image slices associated with diseased tissue or a selected region of interest are identified. The identified image slices are then stored and used in acquiring subsequent magnetic resonance imaging signals. The baseline and subsequently acquired magnetic resonance imaging signals are then processed to determine changes in location, size or other factors that provide an indication of whether treatment is effective. In another aspect, baseline and subsequent magnetic resonance parameters are also acquired and compared as part of determining the effective of treatment.
