We present an application of Pattern Recognition technique for analysis of DCE-MRI data from patients with prostate cancer and after prostatectomy. Our analysis indicates that we can detect the area of tumor burden in the prostate as well as abnormalities suggestive of residual/recurrent tumor in the prostate bed. The constructed 3D maps can be directly imported into DICOM-RT ready format to the RT planning system for targeting of the contrast enhancing areas specifically in order to improve tumor control and limit toxicity.
