In this work, the decrease of the apparent diffusion coefficient (ADC) in cancerous prostate tissue compared to healthy prostate tissue is investigated using the Intravoxel Incoherent Motion (IVIM) Theory. Moreover , the extracted parameters and the calculated parameter maps are analyzed with regard to the differentiation between cancerous and healthy tissue. Therefore, diffusion weighted images of the prostate of 9 patients with prostate carcinoma were acquired and evaluated, yielding a significant decrease of the ADC and the perfusion fraction in cancerous tissue compared to healthy tissue. The results suggest that the decrease of the ADC primarily comes from perfusion effects.
