1. A computer-based method for generating a parametric response map comprising: a) obtaining a first set of parametric measurement data for a tissue region with an imaging device, the first set of parametric measurement data comprising a plurality of voxels; b) administering a treatment to the tissue region;c) obtaining one or more subsequent sets of parametric measurement data, each subsequent set of parametric measurement data comprising a plurality of voxels, and the subsequent sets of parametric measurement data being obtained with the imaging device or another imaging device;d) registering the one or more subsequent sets of parametric response data with the first set of parametric response data; ande) identifying, on a voxel-by-voxel basis, whether the voxels within the tissue region have increased, decreased, or unaltered parametric measurement properties, using a defined threshold, wherein each of the changes is determined by comparing voxels of the one or more subsequent sets of parametric measurement data to the voxels of one or more subsequent sets of parametric measurement data obtained previously or to the voxels of the first set of parametric measurement data. 2. The method of claim 1, wherein said treatment comprises a treatment selected from the group consisting of chemotherapy, radiation therapy, targeted therapy, cryotherapy, hyperthermia, proton beam therapy, ablation therapy, coagulation therapy, ultrasound therapy, antivascular therapy, and antiangiogenic therapy. 3. The method of claim 1, wherein said parametric measurement data comprise measures of vascular permeability data selected from the group consisting of K Trans, AUC, and leakage space. 4. The method of claim 1, wherein said parametric measurement data is selected from the group consisting of extravascular leakage space data, vascular permeability data, blood flow data, absolute blood volume data, relative blood volume data, mean transit time data, time to peak data, density data, composition data, diffusion data, and diffusion anisotropy data. 5. The method of claim 1, wherein said tissue region is selected from the group consisting of a malignant tumor, a benign tumor, an abnormal growth, an inflamed region, a cancerous region, an infected region, a diseased region, an organ rejection, and one or more organs selected from the group consisting of lung, prostate, breast, colon, rectum, bladder, ovaries, skin, liver, spine, bone, pancreas, cervix, lymph, thyroid, adrenal gland, salivary gland, sebaceous gland, testis, thymus gland, penis, uterus, trachea, heart, and spleen. 6. The method of claim 1, wherein at least one parametric response map is generated based on the processing that shows which voxels in the tissue region have increased, decreased, or unaltered parametric measurement properties. 7. The method of claim 6, wherein the parametric response map shows changes in parametric data as color changes. 8. The method of claim 1, wherein said tissue region is within a living human being. 9. The method of claim 1, wherein said processing with said registering occurs automatically after said obtaining of subsequent sets of parametric measurement data. 10. A device comprising a processor configured to process the sets of parametric measurement data with said method of claim 1 to generate the parametric response map. 11. The device of claim 10, comprising software that comprises said method to generate said parametric response map. 12. A system comprising the device of claim 10. 13. The system of claim 12, further comprising said imaging device. 14. The method of claim 1, wherein said identifying occurs automatically after said registering the one or more subsequent sets of parametric measurement data with the first set of parametric response data. 15. The method of claim 1, wherein a technique for the registration is selected from a group consisting of rigid body, affine (linear) and warping (non-linear) algorithms. 16. A computer-based method for generating a parametric response map that is used to optimize a therapeutic intervention, comprising: a) selecting a treatment designed to target a tissue region within an individual;b) obtaining a first set of parametric measurement data for said tissue region with an imaging device, the first set of parametric measurement data comprising a plurality of voxels;c) administering said treatment to said individual;d) obtaining one or more subsequent sets of parametric measurement data for said tissue region with said imaging device, each subsequent set of parametric measurement data comprising a plurality of voxels; ande) processing by means of a computer said sets of parametric measurement data with a parametric response algorithm such that the parametric response algorithm registers the one or more subsequent sets of parametric response data with the first set of parametric response data, and using a defined threshold, characterizes on a voxel-by-voxel basis said tissue region as having altered or unaltered parametric measurement properties, wherein each of the changes is determined by comparing voxels of the one or more subsequent sets of parametric measurement data to the voxels of one or more subsequent sets of parametric measurement data obtained previously or to the voxels of the first set of parametric measurement data. 17. The method of claim 16, wherein said parametric measurement data is selected from the group consisting of extravascular leakage space data, vascular permeability data, blood flow data, absolute blood volume data, relative blood volume data, mean transit time data, time to peak data, density data, composition data, diffusion data, and diffusion anisotropy data. 18. The method of claim 16, wherein said parametric measurement data comprise vascular permeability data. 19. The method of claim 16, wherein said parametric measurement data comprise extravascular leakage space data.
